Hi Peter, Thanks for the post.
I was thinking more of drives connected to 3rd party controller cards
(like my Siig ATA-133 card) i.e. a drive not connected to the host
busses found on the motherboard. The DA in question currently has
three drives in it (master-slave on the main bus, master-single on bus
0 of the "SCSI" bus = the Siig card). The main reason I asked was that
I tried two casual boots off the Leopard Installer-DVD, with both
failing to complete boot-up (can't get past the initial silver screen
with the rolling "gear") - my suspicion is this 3rd drive, as I can
hear it click/spin down just prior to the "gear" freezing.
BUT, your point is taken; if you and other veteran installers have
found it a good thing to have only one drive running and mounted for a
Leopard install, well, I can do that!
Thanks again,
Dana
