The boot-up sequence for my work PC (running XP 32) takes nearly a half hour to complete. It's an older machine and the HD is encrypted so I understand why it is slow. What I don't understand is what happens in the last 10 minutes when my HD light is on (and I can hear it spinning and the PC is very unresponsive) but no activity shows up in the Process Explorer I/O Bytes section. I'd expect to see some activity there.
Is there another way to determine what process is utilizing my HD?
