    Angry HDD--Few bad sectors, passed, ridiculous Reallocated Sector Count... Fix?

    I've looked on other threads already, but none of them really gave a proper answer as to how to deal with it. Or nothing worked for me. RMA takes too long--and I don't even know if I still have warranty. I also can't afford taking it in since I'm asq poor.

    (I talk a lot, so I bolded the important stuff in the case you just want to skim.) Also, I'm a programming and ubuntu noob. Like, I'm not even in the area of relevance, really.)

    The hard drive still functions alright--it's just that some folders take forever to load, and files have corrupted. Thus the Reallocated Sector Count being some crazy number--18678160 sectors. Apparently SMART has this glitch where it gives too many false positives but I doubt finding out the real number would help much. The Current Pending Sector count is at 195 in value. It has passed the self-assessment and labelled itself as having "a few bad sectors".

    Results of a failed attempt at ntfsfix:
    Code:
    root@ubuntu:/home/ubuntu# ntfsfix /dev/sda
    Mounting volume... Failed to startup volume: Invalid argument.
    FAILED
    Attempting to correct errors... FAILED
    Failed to startup volume: Invalid argument.
    Volume is corrupt. You should run chkdsk.
    Results of a failed zero-ing:
    Code:
    root@ubuntu:/home/ubuntu# dd if=/dev/zero of=/dev/sda
    dd: writing to `/dev/sda': Input/output error
    2350073+0 records in
    2350072+0 records out
    1203236864 bytes (1.2 GB) copied, 81.3818 s, 14.8 MB/s

    What happened is that the partitions on the disk became all screwy after an interrupted defrag.
    Windows 7 wouldn't boot properly after that, and chkdsk and system restore didn't work (just stayed on those screens endlessly without progressing). (Maybe it no longer knew how to access the files?)

    And what I want to do is clean the drive/fix it completely, then re-install Windows 7. If possible. When I tried to install it before I did all this--I was kind of clueless since it asked me which partition I wanted to install it on, and I'm like, "partitions? Do not want--". And then so I tried formatting and deleting the partitions, but it was all "lololol, i dun no wut2 do so wait a sec" and proceeds to make me wait /forever/. Like an incompetent substitute teacher with no idea what it's doing. Or the result of sexual confusion due to a really hot buff chick. ANYWAY.

    DEAR LORDS OF UBUNTU, please (with an organic cherry on top and a mutilated maraschino) provide me with assistance and answers to my query. ; v;)/

    You're probably out of luck. What SMART reports on is the state of the disk at the hardware level. There's no much you can do about that by messing around with the filesystems and partitions on that.

    You Reallocated Sector Count is nonsense, which should ring alarm bells. It looks like either the firmware on the drive or the disk control hardware are on their last legs. Either way, your Pending Sector Count (if it's accurate) would be cause for concern on its own.

    Looks like you disk is kaput. Back up your important data pronto, and get yourself a new disk.

    ...Teaaaars, man. Tears. ; v;

    /Laughs hysterically. I've always had bad luck, though, ne?

    I find it strange though, that other people with the same ridiculous sector counts get warnings and have their disks not pass self-assessment. Mine does, and only says it's a "few". (I'm currently running sudo badblocks -sv /dev/sda >> badblocks.report). Am I fooling myself with false hope? . _.

    Is there any way I can figure out if the issue is in the hardware or because of that defrag interuption?

    I'll head to the store tomorrow and see what they can do and if I still have my warranty. The problem is that I don't think they'll provide me with a new one since it got screwed up from a defrag error.

    Anyone know a good place online to get 500GB hard drives?

    Don't mention the defrag thing, because it's probably not relevant anyway. All defragging does is shift data around on the filesystem, it can't kill disk sectors any more than normal everyday read and write operations. Interrupting it might risk corrupting some data, but it's not going to kill the hardware.

    Just say that the SMART data shows horrendous numbers of bad sectors. If the drive is still under warranty then the manufacturer has to take it back, no questions asked. I'd go straight to the manufacturer of the drive myself, it'd be quicker.

    Anyway--I'm not going anywhere today, so I'd like to at least try to see what I can do at all.

    So... chkdsk. Can anyone help me figure out how to run that on my hard drive? Even though I'm on ubuntu... (I'm on a live USB.)

    first thing I would do is ddrescue (sudo apt-get install gddrescue) the entire disk onto another bigger drive, and then try to recover the files.

    The drive is toast; you need to replace it. If it isn't still under warranty ( and it should be ), then you'll need to buy a new one. newegg.com is a good place to do so.

    Thanks for running fdisk -lu, I wanted to see how it reported on a drive that is apparently failing badly.
    It shows a:

    • 500GB drive sda
    • 4GB drive sdb
    • 2gb drive sdc

    are you running on a couple of USB sticks?
    I guess the 500GB drive is the one that SMART reports all the errors on?

    tigerdirect has low prices. Shipping time and money can be a problem if you need it fast, they are located in South Florida and ship from there.

    I've had two brand new 250GB drives recently that started reported bad sectors right away, I watch (check) new drives frequently now, if the bad sector count increases/changes, quickly (a week), they tend to continue downhill. they were all replaced without resistance at no cost, so that part is good.

    Thanks, and good luck
