Hi,

Before I give Apple a call, i'm hoping someone can help!

The other day I want back to my mac pro (2010 - 5,1 - dual CPU) and I had the grey screen of death :(

On a power off/on, if I leave it 10mins or so it eventually comes up with a folder with a question mark in it, which I understand to be not able to find boot disk.

This SSD was in the superdrive bay, so I moved it to bay 1, still nothing. I then dug out my original HDD with mac OS installed, the one that came with my Mac,and getting the same. Removing all disks gets the question mark folder up a lot faster. Tried in bay 2 too. Tried a different regular HDD in bay 1. removed all peripherals, unplugged all other disks. just keyboard, power and monitor connected now.

I've tried resetting the PRAM/NVRAM and the SMC. I've tried getting it to go into recovery console, but it won't launch that :(

any help/assistance greatly appreciated.

Or is it toast :(

OK, that's a scary moment.

Do you have another external drive with a system on that you could boot from?

OR Do you have a DVD with system you could boot from - hold down C during
start up ? .... or a USB stick with system ....

How about trying your original HDD/ SSD in a USB enclosure and try a boot in case
there is an error to the drive bays / internal cable?

See how that goes for now.
 
Ah, I've also tried mounting my original SSD on a velocity pcie card too - no joy with that.

I do have a USB caddy I can try my disk in tonight.

Thanks for the thoughts :)

it's alive!!!

OK, I think a combination of a few things, I replaced the battery and had a mouse pointer when switching it on, which eventually came up as showing my old HDD. But still no recovery partition. Looks like my SSD has lost at least some, if not all data - including the recovery partition :( re-removed the SSD and was able to boot up into the recovery utility and go from there :)

Thanks both :) We've had some flickering lights in the house the past week or two, maybe a coincidence, but I think i'll get a small UPS to be on the safe side :/
