I'm going to ask the obvious question: After adding the second drive,
and noticing the change, did you try swapping the ports the drives were
plugged into? (To make your first drive back into being /dev/sda
I saw UUID later in the thread, and that'll help you with Linux, but not
GRUB. You'll have to deal with getting the right drive, separately, to
begin booting a system.
Yes, I did. I tried all 7 Sata ports and they all behaved the same
way. This blew me away. Perhaps Sata ports have no unique
position identifier, such as "I am Sata port #1", ... ?
I do not know the hardware/software internals as to how Sata
ports are scanned and in which order if there is an order at all.
I don't know how the BIOS scans ports either but I would bet
that if I had a PATA (IDE) drive, it would come first off as
/dev/sda (or is it /dev/hda?) long before SATA gets scanned,
but don't hold me to this assumption!
As for UUID. I found thast tune2fs -u random <device> was
the way to place UUID on a partition. I haven't tried it yet but
will do so as soon as the VERY slow dd clone completes a
750GB transfer at 3.0 MB/sec rate - it's gonna be a long
