I misread your statement above as referring to bypassing the disk cache rather than the os cache - but from what you said later you may in fact have meant the former anyway.

Actually, I know how to get Windows to not cache, but I don't know how to tell the disk not to do that. If there is a feature, I will have to find a way to do it through the os.

Without rebooting into Win2K, my recollection is that you get to the feature through the device property *** for the particular disk. Should you be running Linux, I think it's controlled by their disk utility whose name escapes me at the moment (<something>parm?).

....

What might be better (for me) is if I could tell
the disk to never cache writes through some manufacturer's disk utility.

The only thing you'd have to worry about then would be whether the OS would decide it knew better and turn it on again. Going through the OS mechanism (so that it *knew* what you wanted) might be safer.
