    I am planning to replace the HDD in the mini with SSD. This is late 2012 mini.
    The HDD that comes out, I plan to use as Time machine after SSD is in.
    With that in mind and also to make the SSD drive ready before putting it in, I bought an enclosure, but unfortunately it is bus powered (USB 3.0).
    I am not sure if the HDD will work in the non externally powered enclosure.
    Will this work or I should strictly get one with the adapter?
    Thanks in advance for your suggestions..

    If it's a 500GB 5400rpm drive then there's absolutely no problem.

    If it's a 1TB 5400rpm drive then check with the manufacturer. All the big boys in the marketplace offer bus-powered 1TB externals, but some of the badgeless no-marks ship with 'Y' cables (ie they require power from *two* USB ports).

    Have you, um, read the accompanying documentation? :)


    EDIT: USB3 can pump out nearly double the amperage of USB2, and USB2 is capable of bus-powering 1TB 5400rpm externals.

    If you want to avoid problems, best to look for a enclosure that can run from either bus power OR its own external power supply.

    Here's one that has the option to add "power in":
    Note: I don't know if it includes a power adapter. If it doesn't, it probably wouldn't be difficult to buy one on ebay, or use one of those "universal" power brick kits that you can get from a place like partsexpress.com ...

    If you still have the standard 500GB 5400RPM drive in there that came with it, you should have no problem running that off a bus powered enclosure.
