    I have misplaced my seagate external drive power adapter. I checked online and found a seagate drive like mine and the specs for the adapter are:

    Input voltage: AC100-240V, 50/60Hz
    AC Input Current: 1A MAX
    Output voltage: 12V DC

    I found an adapter from a WD drive I have and the only difference is the AC Input Current is 1.2A

    Will the 1.2 work or will I fry my drive if I use it?

    It should be fine. If it was the other way around (powering a 1.2A device from an adapter rated for 1A) then you could run into problems.

    The specification for maximum input current is unimportant.

    What is important is the OUTPUT current.

    The replacement must be at least as high as the original.

    It Worked!

    Thanks Raven & Steve for your input. I tried it and it worked perfectly. I appreciate your speedy replies. Take care.
