Stumbled onto this link today - a DIY "hard disk selector" - mod a 'Y'

cable to selectively power one of two hard-drives.

[I like his idea of switching the power from drive to drive, BUT he
doesn't offer a warning to do it only with the system powered off. The
transients or sparking might be dangerous for the drives or the power

Does anyone on the list have a solution they'd like to share?
Anyone know of commercial ATA or SATA 'selector switches'.

The oldest solution I know is 'disk carriers' or removable trays - which
can be problematic (limited contact life).

With external SATA, the problem eases - it is supposed to be 'hot
swapable', but I've never played with SATA.
Anyone know about m'boards settings for booting off SATA - especially
external SATA?

[I'm guessing that e-SATA only comes as a PCI card.  Anyone know of SATA
to e-SATA adaptors?]
