Thanks for the tips, but I think I just "heard" my problem. Torrenting, reading forums, and I hear CLICK, as if my hard drive just spun down. Well, upon reboot, it didn't spin back up, so it must have shut off and turned back on very quickly.

This is a known issue in my setup. Maybe my power supply is too weak to drive three IDE hard drives. Trick is, this hasn't happened in the 3 months since I've installed XP with three HDDs.

Is BT, on any client, causing so much disk activity that it requires more extra power than I can provide?

I should just take that third drive out, after moving the rats nest of data off of it.....
