Thx for ur replies. and to answer ur questions ponch here is some info: - yeah it has been working good for like 3 weeks now! before that sometimes it asked me 2 format it just out of te blue. i didnt do it, just restarted my pc a few times and then it worked again!! - no its not partitioned - i got xp home edition with service pack 2 - well have music on it which in my books is really important and some pics - no i havent formated it! A few hours after i posted the question it worked again..... but i think in a few days it will give the same s*** again! Just wondering if its maybe my fault or if that hard drive has problems with more people then just me! :? thx for replies!
