I have a client with an seagate external hard drive. she does not have the power cable. I have a cable with the correct volts but the amps are different. the drive uses 1.5 and my tranformer has 2.0 amps. From what I understand, this should be fine as it will only draw the amps it needs. Is this correct?

The problem with the Amp ratting occurs when you use a lower rated Plug Pack than what the device needs.

Only thing to check here is the polarity of the Plug that plugs into the enclosure. If it's different to the correct one you will blow the Diodes in the Power Board.

Magic smoke is magical because it's very expensive and it cannot be put back into electronics, no matter how hard you try.

Reverse polarity sometimes causes LEDs to be transformed into NEDs, SEDs, or FEDs

LED = Light Emitting Diode
NED = Noise Emitting Diode
SED = Smoke Emitting Diode
FED = Flame Emitting Diode
