Had similar issues with some machines at work--namely, ultra-portable
laptops with slow hard drives. When Windows was resumed from standby, the
hard drives were taking a while to spin back up--and Windows was trying to
access them before they were ready and timing out. After a set number of
errors, Windows will set the drives to PIO mode, and no other change I tried
could re-enable DMA. I finally found this article that showed me where the
in the registry to reset the maximum allowable mode and how to modify the
system such that the error counter is reset to 0 after a success. Before,
the counter was never decremented or reset...it was always growing.

Note that you must be running SP2 for the reset-on-success modification to
function. I didn't use the VBScript referenced, I manually set the registry
values and rebooted the machine.

Hey,
A while back someone gave me an older PC that I set up for my youngest
daughter. It is a PIII 700Mhz machine running XP Pro and 512MB RAM.
The system started running slowly. I tracked it down to a very high
interrupt processing time (30-90% viewed via process explorer). The
drive
is stuck in one of the PIO modes. I ran the registry mods that I think
I
got from here a long time ago and it did not fix it. I tried various
things
that I found out via Google, but still nothing. I even replaced it
with
another drive thinking that it might be a drive issue. But it is the
same
old thing.
Anyone know what else I might try? Do you think it might be the EIDE
controller on the MB? I could put a Promise EIDE controller in there,
but
most likely I'd have to format and start over.
Thanks,
Bobby
