I was referring specifically to the HighPoint 'RAID' cards referenced
in the thread.
I totally agree with you as regards what a _SANE_ card should do - my
question was whether or not these cards are in fact of the NOT SANE (in
insane) variety.

| Most sane cards store information on the disks, just as Linux does. Some
