also, I also think Tony has some sort of hardware issue other than the 
SCSI controller, as he said it froze, etc. I know that the drives he has 
are definitely questionable and if memory serves, the mobo in that 
particular box he is using to try this stuff on is pretty bad as well.
Tony, if you want to play with that stuff again, give me a call, I've 
been swamped lately but I'll make some time for that, I wanna play with 
the RAID stuff too.
