Jim, it's correct that ASP shows the card as SCSI. All PCI ATA cards do
this. The card is somehow emulated as SCSI to work so that's OK.
You did break the 137GB barrier indeed, and yes the theoratical transfer
rate is 133MB/s since Maxtor HDs are ATA133. In real life the rate is of
course a bit slower.
Didn't you have to format the drives, because usually they don't show up at
ones after disconnecting from the mobo and connecting to the PCI ATA card.
I myself bought a Sonnet PCI ATA133 RAID card with two Maxtor 80GBs for my
B&W G3. I had to format them both to show up. They're now running in RAID0
and my G3 acts as a server for my home network :-)

HTH,
