I recently started to have issues with my laptop being very slow. I ran a hard drive benchmarking tool (by ATTO) that showed that the write speed was very very slow on my boot drive. I ran the same benchmark on my usb drive and it was 650 times faster than my boot drive when it came to writing. Reading is very fast/normal on both.

I swapped out an identical drive and ran the same benchmark. This time the drive showed proper write speed. Thinking that I had a hard drive going bad I cloned the old one onto the new one.

I managed to clone the problem too. Anyone have any ideas on what in WinXP SP3 might be causing the write issues? I am on a corporate network and we have commercial anti-virus software installed. (AVG I think) I regularly run defraggler and have about 40 gig free on a 100 gig drive. The machine has 4 gigs of memory.

Any ideas?

TIA J
