    I have a bunch of bad sectors on a Western Digital 640gb hard drive. Seems like most of the bad sectors are in one place. Odd thing is, the system boots up OK and is still mostly usable. Antivirus and Carbonite hang when they hit the bad sectors, but the system is OK.

    I'm using the UBCD4Win , the ultimate boot cd for windows, to try and copy the old disk contents to the new disk that WD sent out to me. I really don't have time to rebuild the OS since i'm right in the middle of the semester.

    The problem is, on the C: drive where all the good stuff is, the program, Easeus , can't copy around the bad sectors and gets stuck. Do you guys know a program that will skip the bad sectors and just go go go for whatever it can get off the disk?

    Last night I left easeus for 8 hours, and this morning it had 329 read errors, and had been hanging at the same place ("Copied 3.26 GB") for most of the 8 hours.

    Are there better utils on the disk? The WD Disk checker says "Too many errors. Please RMA this disk" Its actually pretty funny I will post the picture later.

    Thanks in Advance.Rajat

      Hi rqbanerjee

      Xcopy and xxcopy have options to ignore read errors

      so can copy most files off bad disk onto good disk

      someone more experienced can give you better advice

        Unstoppable copier can also do it but chances are you will likely still need to reinstall Windows and your programs...
        Plan A is always more effective when the device you are working on understands that Plan B involves either a large hammer or screwdriver....

          How about HDAT to repair the bad sectors so the cloning can commence?

            You can boot from a Live Linux Distro like PartedMagic or Knoppix and either run dd:
            dd if=/dev/old_disk of=/dev/new_disk conv=noerror,sync

            or ddrescue (if you have a lot of bad sectors):
            ddrescue -n /dev/old_disk /dev/new_disk rescued.log
            ddrescue -r 1 /dev/old_disk /dev/new_disk rescued.log

            You can read about it from the author of TestDisk here: http://www.cgsecurit...maged_Hard_Disk

              dd.exe is already included in UBCD4Win.
              dd if=\\.\PhysicalDrive0 of=R:\Backup.img

              If you're afraid of taking any chances then the chances are great that you will never learn anything
