    sda woes, not found in /dev fstab or mtab

    I was running Windows XP on my PC, and for some reason it crashes (not a rare occurrence, haha). After finding no other alternative, I turn off the PC using the power button on the front of the case. I reboot, and it greets me with the phrase:

    "Error could not load operating system"

    D:

    I then load up Crunchbang Linux 8.10, an ubuntu derivative and attempt to assess the problem. Here is the reading from dmesg dev | grep sda :

    I tried lsscsi, here's the output for that:
    Code:
    [0:0:0:0]    cd/dvd  _NEC     DVD_RW ND-3540A  1.01  -       
    [2:0:0:0]    disk    ATA      MAXTOR STM316081 3.AA  -
    I know that my HDD is a Maxtor, so this at least shows that Linux can 'see' the HDD. There's no entry for it in fstab or mtab, and no "sda" in /dev . I hoped to use Ubuntu to wipe the disk and/or fsck it, but mounting it seems to be the main trouble here. Any ideas?

    Re: sda woes, not found in /dev fstab or mtab

    It sounds like you have a hard drive that is going bad. I would suggest going to Maxtors web site and downloading the diagnostic tools and run them on your hard drive. I stopped using Maxtor drives several years ago, but there was a utility to re-certify the drive that saved my butt several times.
