I've got a MacBook Pro here that won't boot at all, it just goes to the grey icon that's a folder with a question mark.

So I boot into Internet Recovery, and get to the Disk Utility. It lists the internal HDD, but all the Verify/Repair buttons are grayed out and unclickable. Boo! :(

So I go into the terminal :cool: and try to mount or repair it by using the diskutil terminal commands. Still no luck.

So then I try fsck_hfs on it (dev/disk12), but nope it's still not liking it.

I've done a couple of reboots, SMC/PRAM resets etc, but still all I can do is boot into Internet Recovery.

But now in the Disk Utility GUI the disk is gone :eek:. That's no big loss, as all the Verify/Repair buttons were grayed out anyway. But if I open a terminal window and do diskutil list, it's not listed either. All I get are the various volumes being used by the Internet Recovery mode. The broken HDD dev/disk12 has now disappeared after doing fsck_hfs.

Any ideas what to do?

If the disk is dead that's fine. But earlier on it was appearing in diskutil list as dev/disk12 (just not allowing itself to be mounted or repaired or anything)... but now the disk has completely disappeared and there's nothing at dev/disk12!
 
Can you take your HDD out of the MBP and put it into a caddy? If you can boot using the disk in the caddy then it's probably the cable that needs replacing.
 
It was indeed the cable, and not the actual HDD itself. Got off very lightly!

Not quite sure though how the cable broke given that it's hidden away inside the aluminium body without movement etc.
