    Default Ide hd problem

    Hello,

    I have two partitions on a Ide drive that won't mount anymore after a
    reboot. They were mounted. Two other partitions on the same drive that
    were not mounted, still mounting correctly.

    The root partition is on a scsi drive.

    fsck.ext2 says :

    /sbin/e2fsck: Attempt to read block from filesystem resulted in short
    read while trying to open /dev/hda4
    Could this be a zero-length partition?

    and syslog says

    Jul 1 23:30:17 Nicolas kernel: hda: read_intr: status=0x59 { DriveReady
    SeekComplete DataRequest Error }
    Jul 1 23:30:17 Nicolas kernel: hda: read_intr: error=0x40 {
    UncorrectableError }, LBAsect=24000482, sector=2
    Jul 1 23:30:17 Nicolas kernel: end_request: I/O error, dev 03:04 (hda),
    sector 2
    Jul 1 23:30:22 Nicolas kernel: hda: read_intr: status=0x59 { DriveReady
    SeekComplete DataRequest Error }
    Jul 1 23:30:22 Nicolas kernel: hda: read_intr: error=0x40 {
    UncorrectableError }, LBAsect=24000484, sector=4
    Jul 1 23:30:22 Nicolas kernel: end_request: I/O error, dev 03:04 (hda),
    sector 4
    Jul 1 23:30:27 Nicolas kernel: hda: read_intr: status=0x59 { DriveReady
    SeekComplete DataRequest Error }
    Jul 1 23:30:27 Nicolas kernel: hda: read_intr: error=0x40 {
    UncorrectableError }, LBAsect=24000486, sector=6
    Jul 1 23:30:27 Nicolas kernel: end_request: I/O error, dev 03:04 (hda),
    sector 6

    What does that mean, and how can I repair this partitions ?

    Thanks.

    Nicolas.

    I can answer only from an ATA perspective. The disk Status register
    contents are given and of note are the UNC bit and ERR bit are set. This
    means you have hit a hard read error on the LBA's with
    UNC(UncorrectableError) bit set and the others just have some sort of
    error. The Error register is not given which is a shame.

    Anyhow, the UNC means your drive is failing or the drive lost power in the
    middle of writing a sector to the media. In the latter case, re-writing
    those sectors will recover them, what you would write to them is the big
    question.

    And how write something on that partition ?
    2 of the 4 partition work perfectly.
    On the less important of the 2 failled partition, I tried a mkfs.ext2
    and it works fine, but the data are lost. I had to recover the data on
    the forth.
    Help is requested ;-))

    I don't know anything about how do this with an OS. I just write low-level
    IDE drivers for embedded systems. You'd need some sort of disk tool that
    could write to the faild LBA's (logical block addresses, the ones that
    Linux reported having trouble with). Doesn't Linux have some repair
    utility? Can't fsck help you fix the partition?

    I tried every option I know but the partition is inaccessible !!
