There might be another thing going on here. The (e)IDE bus doesn't
behave well when
multiple devices are doing I/O. That's one of the big advantages of
SCSI.
If I'm using iTunes to import a CD (Tchaikovsky) it takes 11 bounces of
the Dock to
load MS-Word. If I do it without iTunes it takes 4. Launching F1
Championship demo
from a FireWire drive during an iTunes import only takes 4 bounces.
So, if you move some of that I/O activity off the internal eIDE then
you shouldn't see
that beachball so much.
