  1. I have a WD 456 GB hard disk, which I have been using since Feb'10. But now when I connect it to my USB port (Laptop Dell D630) , the "My Comp" hangs and I have to remove the disk. i have tried to change the wire of the HD but no effect.

    The hard disk gets ON and the LED on the hard disk blinks like normal.

    Please do suggest any possible solutions ..

    And also suggest some data recovery software that works good.

    Does the disk have an external power source, or is it just powered through USB?

    Also, have you tried turning the laptop off, connecting the drive, and then turning the laptop on?

    If the above does not work, test it on another computer, both with plugging it in while the computer is on, and if that does not work, plugging it in while off and turning it on.

    rchopra, this is a possible sign of a failing external drive.

    Run hard drive diagnostics on drive.

    In addition to above possibilities, some additional tips/tricks to check/try

    > Most important: Have you tried using the drive on a different computer???
    > Also remove the battery AND unplug laptop from AC socket and leave laptop overnight like that. Then try again in the morning
    > Also, does USB drive have its own AC power? Power it off. Plug in USB in first. Then turn drive back on

    Also see if this might help [post=875300]How to Cleanup and Remove old USB Storage Drivers[/post]. Before talking data recovery, you should see if drive works on any other computer.
