Simon,
I believe the 3ware controller effectively hides the IDE nature of the drives
from the OS/bios and I doubt if the drive vendor's tools are smart enough to
work in a 3ware environment.
Are you suggesting that in a 3ware environment, one should move the IDE drives
to a computer with standard IDE controllers; turn off the write cache, then
move them back behind the 3ware controller?
I can see that working if the drives store that piece of their config in
Non-volatile RAM, but I don't have that level of knowledge.
If that is what needs to be done, I can certainly do it, but it does seem to be
a pain.
