I have two identical hdd and one seems to be roughly 32 times slower than the other drive. Both hard drives are WD2500s. I am not exaggerating. Anyway I've had the fast one for a few months and the slow one I purchased just recently. I posted some other issues I had with the drive here but never got an answer. I'm about to give up on this drive and unfortunately theres no possibility of returning it. Please help me if you can think of. If you need any more info ask.
