Stuck on PIO only

[Lucius Snow]

Hello all,

I've got a problem with a Western Digital 60 GB ATA100 drive which runs in
PIO only. So the speed goes around 2 MB/s only. The BIOS recognizes it well
as UDMA5 but Windows XP (+SP2) see it as PIO only althought "DMA if
possible" is selected in the IDE controller. The motherboard is an Asus P4PE
and the chipset an Intel i845. So i've tried again after installing the
chipset utlity but no change.

Another hard drive, the same model, had the exact same symptom on my machine
with another hardware configuration (chipset Intel i875). Of course i
already tried different cables at 80 pins. My last attempt was to uninstall
the Primary IDE channel in the device controller and reboot. I already did
it in the past. However, this time, i got a blue screen 7B when restarting
Windows. I've never been able to fix that error except by doing a repair
installation of Windows.

Any suggestion appreciated.
Thank you very much.

I had this problem on my last computer, (secondary channel) I found that if
I uninstalled the hardware then reinstalled it (takes one minute) it would
revert back to DMA for a short time.The article above explains why and their
is also
a link to contact M/S for a fix.

I have seen this many times. Click Start-Run-Type Devmgmt.msc and click
OK. Expand right click and uninstall all of your IDE Controllers as
well as your hard drive. Now install these chipset drivers:

fixed the problem

Whoop, just thought about this right after I sent my last post. Try
Intel Application Accelerator from here if none of my previous
suggestions worked:
