Ok so it's 2016. How is everybody doing? I had an intermittent clicking on my i7 Late 2012 server. Two 1Tb disk drives. Here's the problem. I've been nursing the machine the entire lifespan. It seems that at these hard drives are slow, or something has always been wrong with the drive and/or controller.
Now I installed 10.11.3 (El Capitan rev 4) onto the main HD and guess what. No boot. Verbose didn't show anything. Safe-Mode didn't ever come up either. I can still see my data on the disk, by booting off another device. I think I've had a lemon the entire time. I've tried everything including DiskWarrior 5 but nothing has brought the boot back (it does boot into Recovery though strangely).
It hangs on the progress bar and the Apple even in Verbose mode. The bar moves, and then slowly stops at around 65%.
I thought it would be no problem to get the OS upgraded. But now it's totally dead. My last resort is to take the drive out and try SpinRite on it.
Has anybody else had to deal with a hobbled, limping Mini for the last three years?
Report back! This could be VERY handy information for everybody.
