Big Y for shutdown drive, prior to that though, unmount all
partitions on drive, tell drive to spindown, pull data lead,
pull power lead. Nothing will fry, no oops 'cos filesystem not
mounted. If you talking RAID1, I have no idea.

Another drive on same ribbon might get confused --> dataloss.

Sort of reverse order going other way, power on, data connect,
not something I would expect to work, need BIOS support, AFAIK
linux still needs reboot to re-read drive geometry, unsure.

I'd also suggest USB enclosure, safer, saner, and cheap

--Grant.
