Hi, I have a 2010 mac mini which has been fantastic. At xmas I put an OCZ Vertex 4 in it and no issues nice and fast. The original drive got put in an external case formatted and encrypted and i moved my iPhoto and iTunes gubbins there. A week ago the external drive password popped up which was odd because it was stored in my key-chain. I the noticed the drive was called +---...---+ and not "Mac HDD". so i unplugged it and I can see the partitions on my windows PC. Mac wouldn't recognise it. Yesterday I switched it on an it would not boot. Tried several times and nothing, it chimed the first few times but now doesn't and no longer shows any output on the monitor. Help... it seemed to not boot when anything USB was plugged in. I have tried resetting SMB & PRAM etc but no joy? I am proficient with Windows but not had any experience with macs going wrong. Also are there any utilities that will let you pull utilities off the time machine usb drive I had plugged in? Many thanks in advance!
