How to fix crc error in a portable hard disk?

My 1TB Toshiba 2.5" external hard drive has become inaccessible. I can't even access it to run check disk. I was originally just getting crc errors for my torrent files, but now I can't do anything. I am trying to resolve the issue using "Tune Up Utilities 2011", but the drive is still inaccessible. What must I do?....please help!!!

    At the very least the file system has become corrupt, so you should format it. If the problems persist then the drive is failing and should be replaced.
  2. I have formatted the disk with the help of "Paragon Disk Manager' and then recovered the lost data with the help of "icare data recovery".
    But still, I am facing problem in copying files, the system gets hanged and some error is displayed. Now I have asked the vendor to replace the disk.

  4. Hi, there!
    I've had the same problem for the past few days. I tried all tips given on the issue, but in vain. But in the end I came up with my own solution.
    I borrowed my friend's laptop and used it to format my own HDD, which is by the way Toshiba. I logged it and erased all partitions. Since crc issues lurk at the very begging parts of the hard drive, I discarded 10Go from my hard drive to prevent any dysfunction and hidden that 10Go from appearing. Then, I partitioned the rest to C: and D:. I granted primary partition to both C: and D:. And that did the trick.
    Once, I ran a chdsk using Hp start up utility, it did'nt catch hold of that 10Go in question. I proceeded to the installation of the OS. Up the now, everything seem ok.

    By the way, I used to hear some kcrrrr sound when I used to copy something what ever drive is, now I don't here that sound anymore.
    Hope it'll work for you the same way
