my 4TB Seagate HDD is failing in a very strange way:

I noticed an issue where my PC would just outright hang for a minute or two occasionally when swapping to the 4TB HDD. When I look at logs, when it hangs, the 4TB HDD times out but then on a retry IMMEDIATELY reads whatever sector just fine. In fact, it reads fine constantly for a few days until the same sector has an issue. So, the timeout is a remap, then? No, as the spare sector and bad sector counts in the SMART info don't change. It doesn't even change how many read errors or anything it's had. Strange, but let's test it with Seatools to be sure.

Tests go as follows:

- Short: pass
- Short: pass
- Long: seatools immediately crashes. Reopening seatools, it pulled a serial of all zeroes... okay....?
- Long: seatools immediately crashes. Seatools gets the right serial on reopen.
- Long: pass
- Long: fail
- Long: pass
- Long: seatools immediately crashes. All zero serial again.

i have no idea what's happening

    Neither do I. But I don't have a clue about how drives work anyways, soo *shrug*

    Replace it. If you have one bad sector, you'll soon have others.

    Seagate nicht (sie geht nicht - it doesn't work). ^^

    @Fast-Nop Geh schlafen, du bringst schon dad jokes.

    @Ranchonyx I'm old enough to be your dad, so I'm entitled to these jokes. Oh, and get off my lawn, young boy! ;-)

    @Ranchonyx If you're in your early 20s, that would work out as far as age is concerned.

    @Fast-Nop okay, I take it back.

    Could be a controller failure. Controllers do have rom, don't they? Could it be the rom's flash storage that's failing?

    Not sure if consumer-grade hdds have a cache. If it were an enterprise setup, I'd also suspect the cache - explains it all

    @netikras consumer-grade HDDs have had some cache for a while, like 32MB or so is the recent "higher-end" amount, but yeah. I mean, could be, but it times out on the bus like entirely for like a minute before jumping back to life, but during the drop it's still spinning and such, so it's not power, and the cables and such were ruled out by using many cables, controller by using several machines, etc.

    @Parzi "controller by using several machines" - huh? Have you been moving the plates/controllers around? Between different hdds?

    Is your PC near a window ?

    Does it happen only when the street lights are on ?

    Set of traffic lights near by ?

    Near to a place that does welding ?

    Tried a shorter SATA cable ?

    Tried re-routing existing SATA cable ?

    Tried the test under a different OS ?

    Using Windows 10 ?

    Are you wearing an underwire bra ?

    No, seriously. :-)

    Or a person near the computer is ?

    Google is no use trying to pull up a reference to this decades long story of how one affected a computer !

    @netikras "ruled out the controller by using several machines" yes
  • 1
    @Nanos yes, none nearby, no, no, yes, yes, yes, no, no.

    it's been in many places in the house and like 300 miles away too and it's still occasionally just disappearing off the bus for no reason

    Sunspot activity. :-)

    Maybe stick it in a bag with lots of Boron soap. :-)

    Elevation ?

    Interestingly this reminds me of a bit of a problem I'm having lately, they might be connected.

    Every now and then in W10, my disk usage runs to 100% for no apparent reason..

    Does yours display the same symptoms when its playing up ?

    Mine started a few windows updates away..

    I wonder if its related to that Meltdown/Spectre security fix ?

    Didn't that also include CPU code fixes too ?

    How about a storage disk firmware bug, using latest firmware ?

    Of course, it might be the latest firmware that has the bug. :-)

    I'm reminded my motherboard, even though its rated to use SATA disks on all of its ports, actually has firmware issues with some of them, and this restricts me to using only certain ones for certain speed / size disks to avoid weird issues.

    I'm also reminded of a NAS system I have that only likes one specific model of 4Tb HD..

    My best guess at the moment is to try a different OS with the same hardware and see if the issue arises.

    One reason I always like to have at least a dual boot system, to help narrow down if its a software issue, or a hardware issue.

    Also, recently, I had to update a BIOS to solve some weird problems.
