• USB hard disk read errors

    Yesterday my USB hard disk formatted as NTFS started giving errors. It is mainly read by jukebox applications like Amarok, Clementine or as now, gmusicbrowser.

    Gparted tested it as ok.

    The error is:
    <timestamp> blk_update_request: critical medium error, dev sdc, sector <long number>
    <timestamp> Buffer I/O error on dev sdc2, logical block <long number>, async page read

    Has gnome-disk-utility installed ???

    Can that package serve you to test disk performance

  • Looks to me hard drive just barely trying to survive. I suggest you backup your data asap.

    You can install gsmartcontrol and type smartctl -a /dev/sdc to check the status.

  • Thanks for all the answers! I am already in celebration mode. I will try to get back to this tomorrow.

    I just say that I need to use that disk also in Windows.

  • Hi, I cannot get gsmartcontrol to work with this hard disk.
    Now that I’m at work, I remember seeing these errors also in Windows: Clementine stops playing, and shows it is buffering, all other programs seem also stalled at the same time. I think this began early last week at work.
    I suppose this hard disk is breaking down, there are errors all around the disk. I guess I need to copy the readable stuff out of it ASAP… or are there better options?

    Maybe I can work with:

    $ yaourt -Ss smartmontools
    extra/smartmontools 6.5-1 Control and monitor S.M.A.R.T. enabled ATA and SCSI Hard Drives
  • Thanks @judd! I will try that…

  • How to repair NTFS under Linux:
    Use ntfsfix (from ntfs-3g)

    $ sudo umount /dev/sdXn
    $ sudo ntfsfix /dev/sdXn

    Take in account that ntfsfix can only repair some errors. If it fails, chkdsk (from windows) will probably succeed.

  • Hi,
    gsmartcontrol says it cannot enable smart on this USB hard disk.

    This is the device information:

  • @joekamprad ntfsfix checked the disk successfully, but found nothing wrong.

    For me it seems the disk may be ok, but for some reason it has been corrupted. There are files, which cannot be read. Clementine and gmusicbrowser both get stuck reading the disk. When I check the console, it reports read errors here and there.

  • I’ll try the activation in BIOS…

  • @vpp21 as you are banned Windows, you have no optional Windows machine to do chkdsk?

    ha ha ha: 🆓 Capacity: 1 B [1 B, 1 bytes] <— seems a little odd

  • I suppose one letter was printed in white!? :)

    I have once used chkdsk on this disk and it passed without any notes about

    I didn’t find any smart switch in BIOS…?

  • I think I cannot format it fully, because it contains sw to make the hard disk visible in WLAN. It can be used as a film repository for the TV.

    But in order to format the other partition, I need to copy all readable files away to a safe place.

    Testing has stayed in this phase for 35 minutes now. I guess chkdsk has bumped into a byte that cannot be read.

  • Now chkdsk command has been running for 3 hours and 20 minutes with no change in the log and I believe it will stay that way until the end of the working day.
    I really think the disk has worn out. I don’t remember any warranty to appeal to. I will continue copying data out of it in the evening.
