    This is for dbdb,

    Hi, you seem to be knowledgeable about chkdsk, so here is my question. I believe I have some bad physical blocks on my drive, the symptoms being the laptop will sometimes almost grind to a halt but the disc activity lamp is burning constantly. Running chkdsk with the appropriate switches identifies and corrects the bad blocks and afterwards all is well, but only for a few days. My understanding is that when chkdsk finds a bad block or sector it should write the address in a 'spareing' table which should prevent the block ever being accessed again, but this does not seem to be the case because I have seen the same address reported on more than one occasion. I am running Win7/64 ntfs using the delivered version of chkdsk. Any thoughts?

    Hello sle3pingz,

    Yes, chkdsk /f will still detect and fix (mark) bad sectors. :)

    It's no problem at all mate. We are here to help with just such questions. More details at the link below, but here are the basics. :)

    Disk Check

    The /R switch alone only attempts to recover any data that was in the bad sector. It will not attempt to fix or mark the bad sector to no longer be used unless you also include the /F switch below..

    The /F switch alone will attempt to fix any errors on the disk. If it can't fix an error (ex: bad sector), then it will mark it so that the bad sector will no longer be used.

    If you use both the /R and /F switch (ex: "chkdsk C: /F /R"), then it will do both of the above.

    You can run chkdsk C: /F /R to do both at the same time. Just substitute C for the drive letter you want to run it on.

    Nope, I would recommend to run the command below exactly as is.

    F = fix only
    R = recover data only

    chkdsk C: /F /R

    what do you mean by nope Brink?
    chkdsk /f can't detect bad sector?
    then only chkdsk /r can detect bad sector?
