I have a 2012 MBP which someone dropped about 4 feet late last year. I think it damaged the spinning hard disk and is causing me an issue. I am hoping to simply be able to boot up and back off the items that I have stored on it (I have a few things from today that weren't backed up.) Anyone have an idea on how I can get it to boot up again long enough to save stuff? MBP, mid-2012, 15" non-retina (but upgraded to the high rez screen), 8 gigs of RAM, 750GB hard drive. I was on it when it suddenly locked up and I finally gave up to have to force a power down. It was REALLY slow when it woke up and I couldn't even get signed in. I powered down again, and have tried every combination of keys I could. I've tried disk utility repairing the disk over and over (it always fails), I've tried to use internet tools and to use the installed on the emergency boot partition to no use. If I try to boot to single user it gives me an "error loading kernel cache 0x7." If I try booting, I get a gray screen alternating the "prohibited" screen (circle that is crossed out) with the black Apple. I know the drive at minimum needed a reformatting, but for the moment I am just hoping to get one more boot from it to dump the contents to an external drive. Ideas?
