Can't Copy Files To HDD

Hey guys, I own a WD Passport (320GB). I’m having problems in copying files from my PC to the HDD. It was working fine a few days ago but I can’t seem to copy any file though I can easily read the files stored at a very high speed. But the problem is probably with my computer since I can copy files from my laptop without an itch. So guys could suggest what’s going on? How to fix it?

P.S. I use Windows 7 32-bit on both PC and laptop.

Hi there, how do you try to copy the files and from where on your computers?

If you can still read from the drive then take the data out and format it, that’s what I would do…
