Well yes. Sort of. Not a 'physical switch' like a wall switch, but
'physical' enough to control hd's remotely.
If you want to control AC, like for a remote hd box plugged into the wall,
you could use triacs or diacs. The infamous "Clapper" is just a triac
triggered by an scr triggered by a microphone feeding an A/D converter
(very simplistically). If you just want to control the DC lines to
internal hds, you could just use SCRs. And these types of switching gadgets
can be made as exotic as you wish.
Once the hds have these solid state switch solutions in place, whatever the
psu does matters not much. once the drive is power disconnected behind its'
'switch' spikes/sags/whatever is stopped/
absorbed by the 'switch'. This is very old tech from the 60's and 70's. Of
course, if it is computer related, YMMV. Nothing is truly 100% :)
Best,

Well if the PS spiked, then anything connected to it (on or off) could
easily be affected. You'd need a physical switch, not just an electronic
switch, to protect the drive.

What would be really nice is to have a drive that can be turned on my

Why don't have have this already?

I'm glad it works for you.
I see a point of weakness with this method. Both drives are hot all the
time. A errant power supply (power spike/lightening/fire
sprinklers/spilled cup-o-joe/...) could take out both drives.
I used to do something similar with Partition Magic, and a second drive
with it's own power switch. Turn on the second drive power switch, boot
from a floppy with PM and copy the drive. May still be vulnerable to
lightening. But the backup drive isn't hot all the time. Then I
discovered and used removable drive racks; which allowed moving
the backup to a safe location.
Always liked the full working copy instead of a restore routine.
Not to suggest it would work for T, as he was look'n for scheduled backups.
