|I believe the SATA connectors are numbered in order beginning|
with SATA 1, SATA 2, and so forth. However, a boot menu and
the BIOS will probably present you with something like Drive 0
and Drive 1 as the available drives if two drives are plugged in.
Drive 0 would be the same as SATA 1.
By default, the boot drive is whatever is plugged into SATA 1.
So you either need to make sure you plug the new drive into a
connector other than SATA 1, or tell the BIOS to boot from a
drive other than Drive 0.
If anyone understands this better than I do, please correct me!
