Windows 7 not detecting my hard drive

my 80GB WD Passport is not being detected by my laptop when plugged in (by USB). A LED at the side of the external hard drive indicates that it is being powered on even though the computer shows no sign of detection (no sound indication; nothing showing up in My Computer). May someone please assist me in solving this problem? Thanks a bunch.

(guys, formatting the WD Passport is not an option as the drive contains important files.)

try using on XP or Vista

I tried on Windows XP, and it doesn’t work there too.

Another thing I’ve noticed is that the WD Passport would make a repeated clicking noise. Just saying if that is any help.

Nevertheless, thanks for replying.

Is there no one else willing to help? Please, there are irriplacable files in that external hard drive. Thanks again.

Try This


  1. Explorer - right click on Computer - Manage

  2. Disk Management in left window

  3. In lower portion of middle window find your external drive (maybe Disk 1). Try disconnecting and reconnecting USB cable to identify if having difficulties

  4. Right click inside a white rectangular block - Change Drive Letter

  5. Assign a different letter (ex: P) Should be visible in the Explorer as new letter drive.

Good luck.

When I went to Disk Management I couldn’t find my WD Passport in the lower portion. All shown was Disk 0 and CD-ROM 0. I tried reconnecting it, but unfortuanately there was no response. Thanks again for replying though…
