Windows 7: External hard drive shows up in devices but not in my computer

hi computerfriends,

I got a problem, my external hard drive (westen digital 1.0TB) isn't popping up my computer. I can see it in devices (USB to ATA/ATAPI bridge) but i can't acces it. What i've done already:

• Computer Management-> Disk Management. Than ive to initialize the disk, i can choose between MBR and GPT. In both cases i got the error: Data error (cyclic redundancy check). I can't chance any letter
• Downloaded different programs but non of them worked

I've to get my files, it's important. I hope some of you know now the sollution.

Hello indoow and welcome to Seven Forums. Couple of things to try:

1. Try using a different USB port.

2. Try changing the drive letter.

Drive Letter - Add, Change, or Remove in Windows 7

3. If you have access to a live Linux CD like Ubuntu you may find that Ubuntu will recognize the external hard drive in Computer.

4. The hard drive may be going bad. You could go to the manufacturer's web site and look for diagnostic tools to check the drive. Or you could use SeaTools for Windows from Seagate (works on non-Seagate drives as well.)

I would run a chkdsk /r in elevated Command Prompt. That will repair any defunct sectors and save the data of those sectors - if possible.
