I have a mid 2011 Mac mini, 2.5ghz i5 4gb ram that suffered from an hdd failure. Went and replaced it with an Intel 520ssd that worked great till you reboot. Then white screen of death, looked it up online and found that people were having identical issues with OCZ ssd's. So I tried it with a 750 GB Hybrid drive, same scenario, works great till you reboot it. I am doing a fresh install of Mountain Lion via the USB technique floating around the internet. Everything works great and is fast, just when you reboot that is when things go south. Did the internal diagnostics and everything passed. Is this MacMini able to be saved or no longer any good? I was thinking as a last ditch effort replace the drive with an hdd from a Macbook Pro. It's the only other good hdd that I have that has the little apple firmware sticker on the drive. ---------- Oh and I did the clear nvram as well.
