    My flatmate dropped his laptop, while it was running. It appears to freeze occasionally, so I did an error scan with HD Tune pro and it has found about 200 damaged blocks, all near the same place. Is it possible to either fix the blocks or tell the computer to avoid those blocks, without formatting the drive? we have only just installed windows 7.

    The drive also fails a Drive Self Test, and makes a louder than normal clicking noise when accessing the damaged blocks. It does pass a SMART test however. Is the drive physically damaged or will a low level format solve the problem?

    Cheers,

    Enter the commend line. Start > run > command.
    Type: chkdsk /f
    Failing that, type: chkdsk /r
    Tell us how it goes.

    chkdsk /f went through with no errors. chkdsk /r rebooted, and its taking a very long time, but it is picking up bad clusters and and replacing them, so I think we are in the clear. I will do the HD tune test afterwards to be sure.

    Cheers!

    Probably the read/write hradt making contact to the tinist of moments, and damaging the platters... Bad times.

    Chkdsk will take what feels like an eternity. I usually just set it and forget it. Chkdsk /r rebooted because it needs to lock the disk, but it's nothing to be worried about.

    Yeah the chkdsk took a long time, and replaced a few clusters. The HD tune pro test still shows the errors, but I dont know if system will still attempt to use the bad sectors?

    As far as I know, it shouldn't. Windows actually keeps a list of bad clusters, presumably so that the OS won't write to them.

    i'd be tempted to clone the hd and replace it with a new one.

    when you damage the disk, you will likely damage the heads as well, making it less reliable.
