Western Digital 160 Gig HD Won't Enable DMA 100

[Larry R Harrison Jr]

I have a Western Digital 160 gigabyte, 8 megabyte buffer--hooked to an Abit
KD7 motherboard. In the BIOS, I see NOTHING that specifies whether Ultra DMA
is enabled.

In Windows under Device Manager and IDE Channels, there IS NOT an "advanced
settings" for this either. Note: there was earlier, but a utility included
with my motherboard for handling Ultra DMA runs in the system tray and is
installed. This explain this.

Anyway, when I run this utility it shows the Western Digital as being set to
DMA 66 (mode 4) and that DMA 100 is available. I set that mode and "commit
to change." It reboots. When I go in there, it has gone RIGHT BACK to DMA
66.

Tips?

WD Diagnostics has an app that sets the DMA mode on the HDD.
