Long rant ahead.. 5k characters pretty much completely used. So feel free to have another cup of coffee and have a seat 🙂

So.. a while back this flash drive was stolen from me, right. Well it turns out that other than me, the other guy in that incident also got to the police 😃

Now, let me explain the smiley face. At the time of the incident I was completely at fault. I had no real reason to throw a punch at this guy and my only "excuse" would be that I was drunk as fuck - I've never drank so much as I did that day. Needless to say, not a very good excuse and I don't treat it as such.

But that guy and whoever else it was that he was with, that was the guy (or at least part of the group that did) that stole that flash drive from me.

So that's great! I thought that I'd lost this flash drive and most importantly the data on it forever. But just this Friday evening as I was meeting with my friend to buy some illicit electronics (high voltage, low frequency arc generators if you catch my drift), a policeman came along and told me about that other guy filing a report as well, with apparently much of the blame now lying on his side due to him having punched me right into the hospital.

So I told the cop, well most of the blame is on me really, I shouldn't have started that fight to begin with, and for that matter not have drunk that much, yada yada yada.. anyway he walked away (good grief, as I was having that friend on visit to purchase those electronics at that exact time!) and he said that this case could just be classified then. Maybe just come along next week to the police office to file a proper explanation but maybe even that won't be needed.

So yeah, great. But for me there's more in it of course - that other guy knows more about that flash drive and the data on it that I care about. So I figured, let's go to the police office and arrange an appointment with this guy. And I got thinking about the technicalities for if I see that drive back and want to recover its data.

So I've got 2 phones, 1 rooted but reliant on the other one that's unrooted for a data connection to my home (because Android Q, and no bootable TWRP available for it yet). And theoretically a laptop that I can put Arch on it no problem but its display backlight is cooked. So if I want to bring that one I'd have to rely on a display from them. Good luck getting that done. No option. And then there's a flash drive that I can bake up with a portable Arch install that I can sideload from one of their machines but on that.. even more so - good luck getting that done. So my phones are my only option.

Just to be clear, the technical challenge is to read that flash drive and get as much data off of it as possible. The drive is 32GB large and has about 16GB used. So I'll need at least that much on whatever I decide to store a copy on, assuming unchanged contents (unlikely). My Nexus 6P with a VPN profile to connect to my home network has 32GB of storage. So theoretically I could use dd and pipe it to gzip to compress the zeroes. That'd give me a resulting file that's close to the actual usage on the flash drive in size. But just in case.. my OnePlus 6T has 256GB of storage but it's got no root access.. so I don't have block access to an attached flash drive from it. Worst case I'd have to open a WiFi hotspot to it and get an sshd going for the Nexus to connect to.

And there we have it! A large storage device, no root access, that nonetheless can make use of something else that doesn't have the storage but satisfies the other requirements.

And then we have things like parted to read out the partition table (and if unchanged, cryptsetup to read out LUKS). Now, I don't know if Termux has these and frankly I don't care. What I need for that is a chroot. But I can't just install Arch x86_64 on a flash drive and plug it into my phone. Linux Deploy to the rescue! 😁
It can make chrooted installations of common distributions on arm64, and it comes extremely close to actual Linux. With some Linux magic I could make that able to read the block device from Android and do all the required sorcery with it. Just a USB-C to 3x USB-A hub required (which I have), with the target flash drive and one to store my chroot on, connected to my Nexus. And fixed!

Let's see if I can get that flash drive back!

P.S.: if you're into electronics and worried about getting stuff like this stolen, customize it. I happen to know one particular property of that flash drive that I can use for verification, although it wasn't explicitly customized. But for instance in that flash drive there was a decorative LED. Those are current limited by a resistor. Factory default can be say 200 ohm - replace it with one with a higher value. That way you can without any doubt verify it to be yours. Along with other extra security additions, this is one of the things I'll be adding to my "keychain v2".

Last rant was about games and graphics cards (admittedly not received too well), time for a rant about game development houses.. especially you EA.

So yesterday a friend of mine showed me in one of our Telegram chats that he'd modified some cheats in an old FPS game by editing these scripts (not Lua for some reason) that the game used as a.. configuration language I guess? He called the result a tank cemetery 🙃

Honestly the game looked a lot like Medal of Honor to stoned me at the time, so I figured, well why not fire up that old nx7010 I had laying around for so long, get a new Debian installation on that and rip the Medal of Honor: Allied Assault war chest that I still had, and play it on one of my more modern laptops? Those CD's are now very old anyway, maybe time to archive those before they rot away.

So I installed Debian on it again, looked up how to rip CD's from the command line, and it seemed that dd could do it - just give /dev/cdrom as the input file, and wherever you want to store your copy as the output file. Brilliant! Except.. uh, yeah. It wasn't that easy. So after checking the CD and finding that it was still pristine, and seeing another CD in that war chest fail just the same, I tried burning and then ripping a copy of Debian onto another CD.. checksummed them and yes, it ripped just fine, bit for bit equal. So what the fuck EA, why is your game such a special snowflake that it's apparently too difficult to even spin up the drive to be copied?

So I looked around on plebbit and found this: https://reddit.com/r/DataHoarder/... - the top comment of that post shattered all my hopes for this disc to be possible to rip. Turns out that DRM schemes intentionally screw up the protocols that make up a functioning disc, and detecting those fuck-ups is part of the actual DRM.

"I also remember some forms of DRM will even include disc mastering errors/physical corruption on the actual disc and use those as a sort of fingerprint for the DRM. The copied ISO has to include them at the exact same place in the ISO as on the IRL disc and the ISO emulator has to emulate the disc drive read errors they cause."

So yeah. Never mind that I already own this goddamn game, and that it's allowed by law to make one copy for personal use, AND that intentionally breaking something is very shady indeed.. apparently I don't really own this game after all. So I went onto the almighty search engines, and instantly found a copy of this game for download. You know EA.. I wanted to play nice. You didn't let me. Still wondering why people do piracy now? Might take your top suits that suggested these fucked up DRM schemes another decade to figure out maybe.. even given the obvious now.

But hey I wouldn't even care that much if the medium these games are stored on wouldn't be so volatile (remember these discs are now close to 20 years old, and data rot sets in after 30 years or so). You company decided to publish these on CD. We've had cartridges in many forms before, those are pretty much indestructible and inherently near impossible to duplicate. And why would you want to? But CD is what you chose because you company were too cheap to go to China, get someone to make some plastic molds and put your board and a memory chip in that. Oh and don't even get me started on the working conditions for game devs.. EA and co, aren't you ashamed of yourselves? No wonder that people hate game development houses so much.

Yay, almost finished downloading that copy of Medal of Honor! Whatever you say EA.. I've done everything I could to do it legally. You are the ones who fucked it up.

The ridiculous and shameful story of how simply "installing Windows" saved my hard drive from the garbage.
(Also update on https://devrant.com/rants/3105365/)

It started with my root partition turning read-only all of a sudden. Some quick search suggested that I should check the sanity of my hard drive, by running a SMART test, which failed of course. I backed up my data using ddrescue and ran a badblocks over the whole thing, which found around 800 unreadable blocks in a row. I was ready to bid farewell to my drive, but as a last resort, instead of the trash, I brought it to this place where they claimed they can repair the damaged hard drives by "surgery".

To my surprise, they returned my drive the next week, saying it is all well now, and charged me 1/8 the price of a new drive, with a refund guarantee if there was a problem in two days. There was a problem right there: I ran another SMART test which failed again, and also the faulty blocks were still unreadable! So I stormed the place and called for my refund, showing the failed SMART report. The only answer I would get from the staff was "Have you tried installing Windows?".

I usually try to be patient in such situations; I really don't like to declare publicly that "not everyone uses that stinky piece of rotten software you call an OS", but their suggestion seemed totally irrelevant! I got all types of IO errors all over the damn thing and they told me to install Windows. Why? Because this was the only test they would rely on. At last I managed to meet the "technician" there and showed him the IO errors: tried to read the bad sectors with dd and failed. He first mumbled somethings like "Have you checked the connector?" or "Are these the same blocks?", but after he ran out of bullshit, he said "Why don't you just install Windows first and see if that helps?" and I was ready to explode in his face!

"You test drives by installing Windows, just because it will make a nasty NTFS partition and probably does an fsck? If you shut your mouth for a sec and open your eyes you'll see this is a shit load of IO errors we got here: You can't install Windows, you can't even make an NTFS here, because it will try to zero-the-fuck-out the damn partition and it will face the same fucking IO error that I'm showing you right now in almost one single fucking system call!"

"I don't know this kind of test you are using. We have our own tests and they've passed successfully. So all I can do is to give you a Windows CD if you want."

"I don't need a Windows CD. I will just try to make an NTFS partition on the error spot and I will fail."

"Ok. Then call me when your done."

I was angry, not only because I felt they're just trying to avoid a refund, but also because I knew I've lost my drive. But just with hope that I could get my money back, I made a small partition over the error spot and ran `mkfs.ntfs` on it. I was ready to show the failure to the guy, but I looked more precisely and saw that "the filesystem was created successfully!" I was sure something is nor write. I then successfully mounted the new partition, write over it and read it again. I even dd'ed the blocks again, and this time there was no IO error. All of a sudden everything was fine.

I didn't know what happened. Maybe it just needed a write, while I'd just tried to read from those blocks. But anyway, I didn't called the technician guy again. I just thanked one of the staff there and said that my problem was solved. I then ran a successful SMART test and then restored my backup. Ridiculous like that.

I'm still not sure if my drive will continue to live with no more problems. I also have no explanation for what happened. (I appreciate any help on this https://superuser.com/questions/...) But I really like to see the look on the poor guy's face when he finds out that trying to install Windows just saved my ass!
