Hi,

What is the make (OEM) & model # of the mobo or of the branded (Dell,
Compaq, etc) OEM computer you're installing the HDD's in...?

What are the model #'s for the two Seagate's, and their capacities..?

Have you tried the master & slave configuration with the same result..?
Cheers

I built the computer myself, so I suppose, I'm the OEM.
It's a Gigabyte GA-6VTXE mobo, and the two Seagate drives are 80GB
master and 120GB slave. They are both 7200rpm drives. I don't have the
machine here with me, so I don't know the actual model numbers.
I haven't tried master/slave strappings, because an 80 wire IDE cable
uses the plug position on the cable to determine master/slave.
The puzzle is that BIOS says UDMA5 is available, but WinXP downgrades
it to UDMA4, and I'd like to know why.

The drives themselves may need to be set for UDMA5 in order for Windows to see it. I have Western
Digital drives and they have a utilitiy to change the UDMA settings on the drive, you may want to
look at Seagates site to see if they have something similar.

I didnt't find anything at Seagate.com to "enable UDMA 5" the BIOS
actually reports UDMA 5 as being available. I did download SeaTools
and tested the drives with that. They both test OK.
I tried strapping the disks for master/slave operation, and it made no
difference.
I tried removing the slave from the bus, and it made no difference.
I uninstalled the IDE Bus master device in DM, and let Windows re-
detect/install it, and it made no difference.
I substituted the Microsoft Generic IDE Bus Master driver for the VIA
one, and it made no difference.
What I'd really like to know is WHY does WinXP downgrade the speed?
Does it log any testing or errors on the IDE bus anywhere?
