    I have lost the power adapter to my Seagate 3TB - SRD00F2 - external hard drive. I have a few adapters laying around, but Im' not sure whether or not they are proper to use. I'm told my unit is 12W / 1.5 amps. All I can find listed on these adapters are the following:
    * 120V AC & output - 12V DC 1000mA
    * 120V - 15W AC & Output - 12V DC 700mA
    * 120v & Output - 12V DC 500mA

    Are any of these permissible to use?

    Thank you!

    Do you have a desktop computer?

    I'd power the drive directly, take it out of it's housing....

    Surprisingly, I have two of these external HDDs bought at the same time and same shop.
    I would never have taken any notice until now!
    These adapters are identical... Except one is 2A and the other is 3A...Go figure!
    I would try the 1A (1000mA). If it gets warm within minutes, don't use it and get a higher amperage adapter.
    Careful of centre pin polarity though!!
    I can check mine tomorrow if you're not sure.
