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..
