Avg. queue length off the charts

Hi, everyone
When i was throwing a demo zip file (300mb) the hard disk
went berserk (in performance monitor the Avg. queue
length and Pages per second went of the charts), thing is
I have two hard disks 10gb and 120gb on seperate cables
and each with að 768-1000mb swap files and I thought that
made better I/O,also i have a 2.66mhz P4 and 512mb
memory. This is not the first time this happens. Anybody
have an idea what the Bottleneck is.

Regards
Keiser
