i assume you mean power supply, the real drain is at spin up and the
amount of amps needed varies with the size and type of HD, my 5 1/2"
drive uses a 5V/3A and a 12V/30A power supply, but a 3 1/4" drive i
borrowed need much less, better to go for overkill than too little

considering the sucess of the ADAM and the fact that they are
surplus.... i dunno, but im sure you'll blow your HD if you try
using the power supply for that
