slow SATA on P4C800-E Deluxe

Hello,

I have an Asus P4C800-E Deluxe motherboard. It was configured with an a 10k
Fujitsu 36gig SCSI drive (running off a Tekram 390U3D card) as the
boot/system drive and a RAID0 setup of two Seagate 120gig SATA drives
connected to the Southbridge SATA connectors as data drives.

This setup worked fine for months, however, recnetly one of the two drives
in the RAID0 crashed. I pulled it out and, after reformatting, left the
remaining drive to run by itself. My problem is that the remaining Seagate
is running terribly slow. I have re-installed WinXP and have checked the
connections of the cabling etc and all appears ok. What could the problem
be?

Thanks Shane

I don't know if this is applicable to a degraded RAID, but
for ordinary IDE drives, Microsoft causes the data transfer
rate to "downshift" whenever excessive errors are detected.
An IDE drive can drop all the way to PIO (polled transfer
mode), if the error conditions are persistent. There is a
procedure around somewhere for resetting it to full transfer
rate.

See "workarounds" here, for example. I think this applies to
IDE and maybe this will suggest a solution to you.
