Hard drive udma problem.

[CocaCola5]

Can't force udma mode on my Western Digital ata100 40G drive, keeps running in pio mode. My motherboard is the MSI Pro2a with ata100 support, running w2k pro.

Win2k doesn't support ata100 indirectly. I have the same problem, and unless you install the Via 4in1 drivers or the Soltek drivers, you'll be stuck in PIO mode. If you do install the Via or Soltek drivers, your drives will be labeled as scsi in the system, which could lead to problems with burners and dvd players. I'm choosing to wait for SP2...

Btw, make sure that you read this thread before you shutdown your computer.

Basically, once you activate ATA100,Relates to the 2mb write cache on the disk being unable to write its contents to the disk before ACPI pulls the power on the hardware, causing corruption to windows registry data. I have to reinstall my W2K again.

Good call Tompit, forgot to mention that... I had that problem. But it might be too late for someone who has installed it already.

Make sure your stuff is backed up before you shut down. So if it fails to bootup, you won't have as much of a headache when formatting...

I had the same problem with my IBM drives. Using the ata switch utility and bumping them to down to ata 4 got them out of the pio and have them running in UDMA at ata66 speeds acording to the HDtach scores.

You also may want to check WDs website. They have "utilities" you can download to enable or disable 100.
