External HDD I/O device error
I have an external Western Digital 3.5" HDD (HDD+Enclosure). It ran fine for a few month untill I started getting this error recently when I try to move some specific file out of it:
Quote:
Cannot copy <filename>: The request could not be performed because of an I/O device error
(where <filename> is the file name i'm trying to copy)

I tried defragmenting the HDD, re-fromatting it and chkdsk, yet I still get this error.

What could be wrong?

Howdy,

Try this: Device Manager

To get to Device Manager click Start>>Run type devmgmt.msc click OK

Click the plus (+) sign next to Disk Drives.

Double-click the drive you having problem with.

Click the Policies button and then click Optimize for performance.

It's NTFS, and the drive isn't SATA by the way.

I've used Western Digital's diagnostic tool, then the result showed "too many bad sectors". I'm not that good in hardware, can this be fixed through software?

I have the same problem, however my question is that if I would to format my external harddrive will I lose everything because I do have a lot of information on my WD 500gb external hard drive and I don't want to loose all of my saved data!
