    I can't turn it on in bios... There is no such option! It's a laptop -
    hp pavilion zv5260.

    I found a menu HDD SELF-test with 2 options, I tried them both.
    1) Execute SHORT test. Estimated test time: 2 minutes.
            Test status: PASSED.
    2) Execute LONG test. Estimated test time: 75 minutes.
            Test status: PASSED.

    Both tests were successful and didn't result in any errors.

    My filesystem is ext3 (journalling).
    /dev/hda1 - 2Gb - swap
    /dev/hda2 - 7Gb - /
    /dev/hda3 - 70Gb - /home

    I decided to reinstall debian, installing ext3, because I thought may be
    the file system was corrupted. But I didn't touch /dev/hda3, because I
    had some files there that I didn't have time to backup. So I installed
    debian from netinst cd image, formatting /dev/hda1 and /dev/hda2 again.
    It installed without problems. Then I created a folder on /dev/hda2 and
    copied my files from /dev/hda3 to this folder. Then I ran:

    # umount /dev/hda3

    # mke2fs -c -j -v /dev/hda3

    It started creating the ext3 filesystem checking also for bad sectors
    (-c switch) there and it proceeded up to around 10%. After that it
    started giving the same opcode errors (uncorrectable) on each
    consecutive sector. After 40 minutes of these errors I turned it off.
    After I rebooted I tried:

    # mke2fs -j -v /dev/hda3

    without checking for bad sectors and it succeeded creating a filesystem.
    But I don't think I should use it, though.

    So what should I do now? And what do these errors mean? Are these errors
    from the bad sectors? Then why mke2fs wasn't marking them ? Should I run
    mke2fs with -c check and leave for night to finish checking for bad
    sectors ? Or should I check it with another program 'badsectors'? I will
    leave one of them working for night, so that they will have time to
    finish and report the results in the morning...

    /dev/hda2 - root filesystem works fine. From 7Gb I used already 6.5Gb
    and I got no single error. The errors are only from /dev/hda3.

    Is this hard drive dying? Or the problem can be solved? Should I start
    browsing the internet for a new hard drive already?
