"Yes you can, I did, but be aware that the 3B1 power supply can't really

"I blew a 3B1 power supply after trying to do just that (it worked for

it depends on just what drives you have in mind...

the computer shopper had a big feature on hard drives a few months ago.
one of the columns in their *very*complete* table of models was power
rating; it showed miniscribe 67Mb drives at 29w, ex-cdc wren-II hh 40Mb
(my present drive) at 18w, and ex-cdc swift (3.5") 88Mb at 9w.  i plan
to install two of these in my 7300, just as soon as i can get up the
money...

i have no quarrel with mark's *real* argument, that you must observe
the power supply's rating, which is 12v@5a for the 3b1 (anyone know
what else draws 12v?).  just be aware that drive power consumption
varies *widely*!
