"The difference between SSDs and HDDs is that HDDs store data on spinning CDs inside the drive"
-- a 3rd year CS student

Spinning CDs?? CDs?!?!?

Call comes down from the CEO and through his "Yes Man" that some investors are coming by to visit and he want to show off the data center and test servers. There are four full racks of storage servers filled with HDDs and each server has 4 to 16 HDDs a piece.
I got told to "make all of the lights blink", which can be epic seeing it in action but my test cycles rarely aligned that way.

All morning I was striping RAID arrays and building short mixed I/O tests to maximize "LED blinking" for the boss's henchman.

Investors apparently live/die by blinking light progress and it was all on me to get everything working.

My friend has a problem. Please donate hdds.

I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.

So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.

It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.

Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).

Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!

The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.

Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.

So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.

There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D

TL;DR: disaster averted!

Story time!

About a year ago, the company I work for merged with another that offered complementary services. As is always the case, both companies had different ways of doing things, and that was true for the keeping of the financial records and history.

As the other company had a much larger financial database, after the merger we moved all the data of both companies on their software.

The said software is closed source, and was deployed on premises on a small server.

Even tho it has a lot of restrictions and missing features, it gets the job done and was stable enough for years.

But here comes the fun part: last week there was a power outage. We had no failsafe, no UPS, no recent backups and of course both the OS and the working database from the server broke.

Everyone was in panic mode, as our whole company needs the software for day to day activity!

Now, don't ask me how, but today we managed to recover all the data, got a new server with 2 RAID HDDs for the working copy of the DB, another pair for backups, and another machine with another dual HDD setup for secondary backups!

We still need a new UPS and another off site backup storage, but for now...disaster averted!

Time for a beer! Or 20...

That is all :)

"Why does the search take so long?" maybe because it searches through2 dbs with 20 tables with 5.000.000 objects on an 6 year old server with hdds and apparently there is no budget for a new server, but there is money for an 40.000€ art piece.

This happend to me around 2 weeks ago. For some reason, I decied to post this now.

I won the lottery, yey! I mean, bot really, but I am <19yo student, "less than junior dev" in my office, but sonce I am the only one who is capable of working with hardware, I was working month back as a sysadmin for a few days. Our last sysadmin was really good working but really, really toxic guy, so he got fired on a spot after argument with some manager or whatever, no big deal, we could have another guy hired in a week. But, our backup server literally was on fire, all data probably dead because bad capacitor or whatever. This was our only backup of everything at the time. Everyone in full fucking panic mode, we had literally no other working HW we could use for backup, but then comes me, intern employed on his first dev job for 3 months. That day I bought some HW for my own personal server at home (Intel NUC with some Celeron, 4GB DDR4 RAM and two 240GB SSDs for RAID 1. My manager asked everyone in the office for sollution how to survive next 4 days before new server arrives. People there had no idea what tk do and no knowedgle about HW, I just came from a break and offered my components for a week, since there was noone else who can work with HW, servers and stuff like this, manager offered me $500+HW cost if I, random intern, can make it work. I installed Debian on that little PC, created RAID1 from both SSDs, installed MySQL server and mirrored GIT server from our last standing server (we had two before one of them went lit 🔥), made simple Python script to copy all data on that RAID, with some help of our database guy copied whole DB from production to this little computer and edited some PHP so every SQL request made on our server will run on that NUC too. Everything after ±2 hours worked perfectly. Untill a fucking PSU burned in our server and took RAID controller with him in sillicon heaven next night, so we could not access any data unltill we got a new one. Thanks to every god out there, I was able to create software RAID from survived HDDs on our production server and copy all data from that NUC on the servers software RAID and make it working at 3 AM in the night before an exam 😂. Without this, we would be next ±40 hours without aerver running and we might loose soke of our data and customers. So my little skill with Linux, Python, MySQL and most importantly my NUC hardware I got that day running as a backup server saved maybe whole company 😂.
Btw, guess who is now employee of the year with $2500 bonus? 😀
Sorry for bragging and log post, but I was so lucky an so happy when everything worked out, good luck to all sysadmins out there! 👍

TL:DR: Random intern saved company and made some money 😂

My former teammates used to store multiple local copies on their computers, as a form of version control, and pass bits of code on USBs to share their work.

I gave them a fair warning about the importance of working with git, and then one night, I just stole all of their HDDs, leaving them codeless.

I was here, before it was wk119...

This is my desk. There are many like it, but this is mine.

The setup is a little dated, but I love it, and when remote working, I've to use the company laptop anyway.

Specs:
Intel Xeon 4x3.3GHz
16gb DDR3
geforce gtx 680
SAMSUNG evo SSD+some HDDs
3 dell ips displays with display port
And my beloved g15 & g700

Soo I am the only tech-guy in my family and it's a bit like:

Other: You do program?
Me: yes?
Other: pls repair my printer!

And you guys know how awful that is, aren't you? But in my family it gets tougher...

Today my older sister asked me how to save data from a broken HDD. I said I know a guy who's doing forensic on HDDs and he could make that.

She's like: "but a friend of mine said it could be done easier with software"

And yes, it is! But not that successful...

Now's the point she killed me instantly!
She said: "he opened the HDD and said the disks look fine they could be easily added to a new HDD"....

WHAT THE ACUTAL FUCK I SAID NOW YOUR DRIVE IS BROKEN FOREVER! AND THEN SHE INSULTED ME AND BLOCKED ME ON FUCKING WHATSAPP! SHE IS LEARNING WEBDESIGN WHY THE FUCK DON'T TEACH HER THE BASICS OF FUCKING COMPUTERS! Oh for fuck sakes....

Desks seem to be a thing, currently. This is my desk. There are many like it, but this is mine.

dad: yeah sure , that's why no laptop is working well in this house

all three laptops are older than 4 years and use 5400 rpm hdds and also are full of my parent's stuff.

hey ranteros! i like to dream and i know many of us dream of a nice machine to do anything on it, if you want to post the specs of your ideal build(s) (even a laptop, pre-built pc, space gray macbook pro... doesn't matter). and your current one.

here's mine:

ideal: {
type: desktop-pc,
cpu: intel i7-8700K (coffee lake),
gpu: nvidia geforce gtx 1080ti,
ram: 32gb ddr4,
storage: {
ssd: samsung 960 evo 500gb,
hdd: 2tb wd black
},
motherboard: any good motherboard that supports coffee lake and has a good selection of i/o,
psu: anything juicy enough, silver rated,
cooling: i don't care about liquid cooling that much, or maybe i'm just afraid of it,
case: i accept any form factor, as long as it's not too oBNoxi0Us,
peripherals: {
monitor: 1080p, maybe 1440p, i can't 4k because of the media i consume (i have tons of shit i watch in 720p) + other reasons,
keyboardmousecombo: i like logitech stuff, nothing fancy, their non mechanical keyboards are nice, for mice the mx master 2 is nice i think, i also don't care about rgb because i think it's too distracting and i'm always in darkness so some white backlight is great
},
os: windows 10, tails (i have some questions about tails i'll be asking in a different post,
}

i think this is enough for ideal, now reality:

current: {
type: laptop,
brand: acer (aspire 7736z),
cpu: pentium dual-core 2.10ghz,
gpu: geforce g210m 2gb (with cuda™!),
ram: 4gb ddr3,
storage: hdd 500gb wd blue 5400rpm (this motherfucker stood the test of time because it's still working since i bought this thing (the laptop as it is) used in late 2009 although it's full of bad sectors and might anytime, don't worry i have everything backed up, i have a total of 5 hdds varying from 320gb to 1tb with different stuff on them),
screen: 17 inch hd-ready!!! (i think it's a tn panel), i've never done a test on color accuracy, but to my eyes it's bright, colorful, and has some dust particles between the lcd and backlight hah,
other cool things: dvd player/burner, full-sized keyboard with numeric keypad, vga, hdmi, 4 usb ports, ethernet, wi-fi haha, and it's hot, i mean so hot, hotter than elsa jean and piper perri combined,
os: windows 10, tails
}

if you read this whole thing i love you, and if you have some time to spare on a sunday you can share your dream rig and the sometimes cruel current one if you dare. you don't have to share them both. i know many will go b.o.b and say "what you're hoping to accomplish, i already did bitch.", that's cool as well, brag about your cool rig!

TL;DR - (almost) childhood trauma due to Wesrern Digital crap products lead to lot of data loss and a plege to not trust or purchase their products for the rest of my life.

....

So, I got my first ever Wester Digital 2TB Mybook, back when 2TB was a really big thing. While in the midst of moving (not copying) a LOT of data to it, the damn disk just.. died. There was no fall, no power outage, no damage, it just stopped working. I was out of words and out of options. Tried yanking out the disk and connecting it directly to a system, but no luck because it looks like it's the HDD mobo that died.

Also stupid young me did not realise back then that, even if a "moved" the data, the original data is still most likely in their original location, and so, never bothered a recovery.

Lots of good stuff lost that day.

And as with a lot of you, my disaster recovery system kicked up 10 fold. Now I got redundant local and cloud backup copies of all critical and otherwise unattainable data.

As you may have guessed, I never bought another Wester Digital product ever again. My internal HDDs are Segate, and external is a suprisingly long lived Toshiba Canvio.

It's 2022 and Firefox still doesn't allow deactivating video caching to disk.

When playing videos from some sites like the Internet Archive, it writes several hundreds of megabytes to the disk, which causes wear on flash storage in the long term. This is the same reason cited for the use of jsonlz4 instead of plain JSON. The caching of videos to disk even happens when deactivating the normal browsing cache (about:config property "browser.cache.disk.enable").

I get the benefit of media caching, but I'd prefer Firefox not to write gigabytes to my SSD each time I watch a somewhat long video. There is actually the about:config property "browser.privatebrowsing.forceMediaMemoryCache", but as the name implies, it is only for private browsing. The RAM is much more suitable for this purpose, and modern computers have, unlike computers from a decade ago, RAM in abundance, which is intended precisely for such a purpose.

The caching of video (and audio) to disk is completely unnecessary as of 2022. It was useful over a decade ago, back when an average computer had 4 GB of RAM and a spinning hard disk (HDD). Now, computers commonly have 16 GB RAM and a solid-state drive (SSD), which makes media caching on disk obsolete, and even detrimental due to weardown. HDDs do not wear down much from writing, since it just alters magnetic fields. HDDs just wear down from the spinning and random access, whereas SSDs do wear down from writing. Since media caching mostly invovles sequential access, HDDs don't mind being used for that. But it is detrimental to the life span of flash memory, and especially hurts live USB drives (USB drives with an operating system) due to their smaller size.

If I watch a one-hour HD video, I do not wish 5 GB to be written to my SSD for nothing. The nonstandard LZ4 format "mozLZ4" for storing sessions was also introduced with the argument of reducing disk writes to flash memory, but video caching causes multiple times as much writing as that.

The property "media.cache_size" in about:config does not help much. Setting it to zero or a low value causes stuttering playback. Setting it to any higher value does not reduce writes to disk, since it apparently just rotates caching within that space, and a lower value means that it just rotates writing more often in a smaller space. Setting a lower value should not cause more wear due to wear levelling, but also does not reduce wear compared to a higher value, since still roughly the same amount of data is written to disk.

Media caching also applies to audio, but that is far less in size than video. Still, deactivating it without having to use private browsing should not be denied to the user.

The fact that this can not be deactivated is a shame for Firefox.

Rant on me myself.

After being a professional coder (ie having a bachelor degree) for 11 years now, I finally have a decent and reasonable backup.

I use borg to backup to my raid 1, which is local, in my corridor near the ceiling. I use a Intel NUC with two external USB3 HDDs attatched. As I already had data on them, I went for a btrfs raid 1.

The second level of my backup solution is my brother. It's 50km to his flat. He's got a banana pi with my third HDD attached. I connect to his pi via VPN. The VPN is done via an AVM Fritz! Box. No ads, I just like those boxes (modem and router).
The backup is encrypted, of course.

Now, after ten years, I finally got a decent backup solution. Wow. This feels great! 😎

Hey guys.
This was my project for today.
Power supply, 5v USB 25A x2; 12V 10A x2; extra power standard cables to power HDDs and such.
Plus a sand paper whatever it's called :p

Ps: Need to know how to power it without the standart power supply, with cables direct to the brush motor pins. Anyone knows? Have arduinos, l293, easy shields, uln2003a... Would one of this work?

Hope you guys like my 🤪 ideas

What do you consider the best method for long-term cold data storage? And why?

I was looking at some magnetic tapes, but the degradation of magnetic charge is worrying me. Lose a single bit and you're fucked.

Dvds - not sure, some of my old ones are no longer readable. Not sure why tho, they had been enclosed in a dark, room-temp place all the time

hdds -- still magnetic.

Ssds? Idk

...?

recently i prided myself in my high ability to google stuff but i just blank at this problem:

i have 4 HDDs with my photos on it. They are more or less backups of each other, but not quite. The folder structure is convoluted and i am dreading this task since years. I now want to move to a better backup culture and save the data i really care about.

Problem: i may or may not inserted new photos in some versions of the hdds and not in others. So they are like [Photo1], [Photo2], [Photo3] and [Photo4] but [Photo1] contains a,b and d content, [Photo2] contains a and b but not d, [Photo3] contains c.

Now i would like a program that just takes hashes of all files present and compares them and finds differences among those 4 folders so i can combine them in each other. Additional problem points for a being in a different subfolder on [Photo1] as in [Photo2]

Its probably some backup software that can that, but i dont know which one.

Whelp?

unpopular opinion: maybe updates would take under <super long time that's overblown> if you did it more often. Also defrag your standard HDDs like every month (weekly if you really want the performance boost)

So I ordered an SSD. It's 1TB for some programs I want to startup faster. I have 3*1TB HDDs to store some movies, series and personal stuff (you know what I am talking about) and a 128 M.2 SSD for Windows. After connecting the new SATA SSD it wouldn't show up. After half an hour searching for a problem related to the wiring, UEFI configuration and other mythical problems coming to my mind I took the instructions of my motherboard. This was the moment I found out that those fuck faces implemented the biological feature of turning one thing off when using another.

Pro tip: Never test old HDDs with one of those Samsung USB3 to SATA adapters. Always use a test bench with real connectors. It might save you a few believed to be dead HDDs.

A few weeks ago I ordered 2 8TB HDDs so they can run in RAID 1 on my server. Then I discovered that one of them isn't working.
So I sent it back to seagate and got a new fresh one today. I thought I would install it in my server and everything will be fine ...
First thing was to backup all files on the already working HDD and delete the volume, but windows already put a pagefile on it so I needed to deactivate it.
Restarted and notice that windows wasn't doing anything so I deactivated it again and now the wonderful text "Getting Windows ready screen" appeared and after minutes of starring at a non moving image I force-restarted the server and eventually I could delete the volume.
I activated mirroring and thought "I'm ready to go". After 15 Minutes of waiting, the text changed from "Formatting" to "Formatting (1%)". The only thing I wanted to do was yelling ... Thanks Windows .... thanks

Tl;dr Why would someone preconfigure a hardware raid on a server AND NOT TELL ME?

Recently we got a refurbished server that has some nice specs and works quite well. It had six 2.5 bays and came with two 248gb HDDs. But it only included 2 rails, so we needed more, and we got more.

I installed windows on it (yes, some of the software we use is windows only), and for some odd reason the forth HDD (this was the second one that was pre shipped) wouldn't show up in the disk management, which was odd especially considering the fact that the SAS did detect it, and would get pissed at me if I took it out. I was in a rush so I left it alone for then.

I had needed to setup a raid for these, and while I was trying to figure out what was wrong, I noticed that windows can do a software raid so I set it up on the third HDD (which is the first pre included HDD). I haven't actually used it yet.

At some point I stated to mess with the HDD that wasn't showing up (switching them around, etc.), when I noticed that windows saw the raid was setup on both of the HDDs, which made me wonder what was going on.

So I decided to check the SAS to see if there was something wrong there, as it was booting, bios let me know that there was a raid that was in the process of rebuilding, so then I thought "oh cool, windows actually does a hardware raid!" Well actually it doesn't, as I was looking I saw that this raid was only setup on the two HDDs that were acting funny, and therefore it was only coming up as one device in windows. I wasted an hour trying to find that!

I hate having a project to go on with but not being able to :(

For example: I have a project that I want to work on, but I'm currently fixing HDDs and I can't use my computer (which is a backup, therefore quite slow). And I can't stop the HDD recovery process unless I want to start again later.

PS: Am I the only one who deletes his most recent rant when he thinks he has something better to say, and the cooldown is still not over?

I hate the elasticsearch backup api.

From beginning to end it's an painful experience.

I try to explain it, but I don't think I will be able to cover it all.

The core concept is:
- repository (storage for snapshots)
- snapshots (actual backup)

The first design flaw is that every backup in an repository is incremental. ES creates an incremental filesystem tree.

Some reasons why this is a bad idea:
- deletion of (older) backups is slow, as newer backups need to be checked for integrity
- you simply have to trust ES that it does the right thing (given the bugs it has... It seems like a very bad idea TM)
- you have no possibility of verification of snapshots

Workaround... Create many repositories as each new repository forces an full backup.........

The second thing: ES scales. Many nodes / es instances form a cluster.

Usually backup APIs incorporate these in their design. ES does not.

If an index spans 12 nodes and u use an network storage, yes: a maximum of 12 nodes will open an eg NFS connection and start backuping.

It might sound not so bad with 12 nodes and one index...

But it get's pretty bad with 100s of indexes and several dozen nodes...

And there is no real limiting in ES. You can plug a few holes, but all in all, when you don't plan carefully your backups, you'll get a pretty f*cked up network congestion.

So traffic shaping must be manually added. Yay...

The last thing is the API itself.

It's a... very fragile thing.

Especially in older ES releases, the documentation is like handing you a flex instead of toilet paper for a wipe.

Documentation != API != Reality.

Especially the fault handling left me more than once speechless...

Eg:
/_snapshot/storage/backup
gives you a state PARTIAL
/_snapshot/storage/backup/_status
gives you a state SUCCESS

Why? The first one is blocking and refers to the backup status itself. The second one shouldn't be blocking and refers to the backup operation.

And yes. The backup operation state is SUCCESS, while the backup state might be PARTIAL (hence no full backup was made, there were errors).

So we have now an additional API that we query that then wraps the API of elasticsearch. With all these shiny scary workarounds like polling, since some APIs are blocking which might lead to a gateway timeout...

Gateway timeout? Yes. Since some operations can run a LONG (multiple hours) time and you don't want to have a ton of open connections hogging resources... You let the loadbalancer kill it. Most operations simply run in ES in the background, while the connection was killed.

So much joy and fun, isn't it?

Now add the latest SMR scandal and a few faulty (as in SMR instead of CMD) hdds in a hundred terabyte ZFS pool and you'll get my frustration level.

PS: The cluster has several dozen terabyte and a lot od nodes. If you have good advice, you're welcome - but please think carefully about this fact.

I might have accidentially vaporized people sending me links with solutions that don't work on large scale TM.

Had a dream about computers on earth mostly stopping working for no apparent reason, yes, again. But this time, they still work on Mars, so we go there, at least some of us. UAC-esque, Doom 3-ish aesthetics, but in a good way, no death and no darkness. No hell plot though, we’re all fine. Both earth and mars are equally semi-livable, but in different ways. For some reason, we can’t ship new CPUs to mars, and 775 pentium considered a good CPU. We use SQL and HDDs. Elon is also there, but he’s nothing, a peasant compared to other scientists and engineers who are a part of the exodus. I had some problems with food and shelter initially, but @netikras helped me

Not really a dev rant, more of a "home tech support" kind of rant but I guess a lot of devs will relate...

So I was looking at building myself a little storage server, mostly for backups and stuff. This led to the fail of this rant: I thought it would be a good idea to convince my father to switch from using a ton of USB HDDs to get himself a NAS.

This is where I didn't think things through...

The only place he was able to set up the NAS is in the living room. Now I have to use my noise cancelling headphones all day just to not have to hear those HDDs rumbling around in there🤦

(also, I specifically got some super quiet fans for my gaming PC in the living room, but now I realize I could have saved some money and gotten some louder ones, since that NAS is so much louder...)

!rant/story:

Aaayoo issya boi the OG rapper straight outta Compton, wassup?!

Nah, for real, though.: How are y'all doing? It has been a long time. I hope y'all are having a great time (can sense some peoples' incoming negative comments due to corona).

I built my completely new first gaming rig like a few weeks ago after my school laptop stopped showing any signals.

The specifications are the following.:
- Mobo: MSI B450 TOMAHAWK MAX
- CPU: AMD Ryzen 5 3600 (no iGPU)
- dGPU: KFA2 RTX 2070 SUPER OC
- 2nd dGPU: GTX 550 TI (this one gets a new rant/post)
- RAM: 2x G.SKILL Ripjaws V 8 GB 3600 MHz
- PSU: Be quiet 650 W (It was the platinum edition afaik. I originally bought the 600 Watt Gold edition, but somehow they sent me the 650 Watt for no additional charge... which is great for me haha)
- HDD: 2x 4TB NAS HDD in RAID1 configuration (to load all of my games around 2 TB right now. Got the two HDDs for 110 Euro including the SATA Data cables)
- SSD: One Intenso 240 GB SSD and a reused Samsung 256 GB SSD from my old broken Lenovo laptop
- Case: Be quiet Pure Base 500 black with a glass panel on the side

While building my first PC, it was one hell of a challenge. I knew how it all was working in theory, but to put it all together, practically, was a bit of a challenge, but it was a nice challenge. I learned a lot and have a performance gain I could only ever dream of.

I used to play my games first on a Toshiba satellite l750d laptop (around 40 fps in cs:go with the lowest gfx settings) and then on a Lenovo e51-80 laptop (around 30 fps max minecraft with no shaders and texture packs).

Now I play cs:go on Kubuntu with 400 fps at peak with ultra high graphics. It is unbelievable.

I couldn't trust the system when I turned on the fps display the first time I saw it.

Got some 40Gig HDDs at home... the one marked crashes Windows Explorer and short after that the whole System if you plug it into a running Windows

Current dream PC:
Dual EPYC at 128 core/256 thread or higher
1TB of RAM or more
Dual AMD GPUs
Massive RAID 10 array of 7200RPM HDDs, something like 24TB or better
A few standalone SSDs, to taste (at least one of a sizeable capacity, like 1TB?)
Total cost, like $30k or so?

How can you recover data from a ticking harddisk (fell on ground and head is broke)?
I've contacted some persons in market but they are doing it for the price of 3 new HDDs.
Is there any chance to DIY ? Share your theories and experiences.

Please help me before I get mad,
First day with Linux Mint.
Objective: Make a 3Tb Hdd Read and Write, Right now I can use it only to Read.
Finally Installed Linux after some bumps (bad ISO).
I have 2 HDDs, the SSD with Linux and a 3Tb HDD
Right now the 3T has 4 partitions, one for windows, 3 for personal use with lots of personal stuff I can't lose.
I've been looking for videos, tutorials and the maximum I got was to had one partition mounted as a folder

# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda1 during installation

What am I missing?
PS.: Next: Make fingerprint work in Linux

Today I came to work and all our main systems where offline (Gitlab, Artifactory, Time tracking, ...). Found out that one of the HDDs of our server (external hosted) died. I started copying some stuff from the second Raid hdd (just in case and because our backup is of course not complete [#notmyfault]) while their datacenter had a power outage.... I'm now waiting for our server to come back to get our systems running again

I thought BFQ (Kernel 4.12) should be faster on good old hdds. In fact, it is. I'm amazed. Well done. Unfortunately my machine freezes randomly every few hours. 🤔

I have the creeping feeling that my laptop is going to kick the bucket (in some way or another) soon. I've had two laptops die on me, both times it was something breaking inside the HDDs and I ended up loosing almost all of my data in both cases.

This time I want to be prepared. How do you guys back up your stuff? Is there a way to take a complete image of all my files? (for windows) or should I manually sift through my files and save them in an organized manner on an external disk?

Is it just me or is it annoyingly finnicky to get an android device connected to Linux? I want to transfer files but its not getting mounted (unlike all my other devices like USB sticks/HDDs). And yes mtp is turned on on my device. How do you guys do that? Any convenient way? In this case I would actually appreciate a non CLI method
