OSX Froze, Fails to Boot in any Configuration In the middle of working like a charm, my MBP locked up. After a bit, I did a hard power off. Here's the timeline since then


Reboot. Got to user screen just fine, logged in. Applications all started up, but beach balled as soon as I moused over them. Everything stopped responding. Wait. Another hard power off
Reboot. Eventually apple logo turns into the deadly circle with a slash through it. Hard power off
Reboot into single user mode. CMD + s on power up. The terminal output finds my SSD, but goes into an endless loop trying to mount and resulting in:


disk0s2: media not present

...

hfs_mountroot failed: 6

cannot mount root, errno = 19


Hangs in this loop forever. Hard power off
Single User mode is the only of the boot options that gets anywhere now
I've cleared the P Ram, tried to boot into recovery mode, safe mode, and tried booting from the recovery drive. Nothing gets anywhere but a gray screen. 


Basically it all points to a hard drive failure. I installed a new top-of-the line SSD about 6 months ago, and with a couple million hours for a MTBF, I feel odd to be about 5000 standard deviations away from that average. 

I'm wondering if anyone has any more advice for me to try before I swap the drive out and reformat it.
Sorry to say it does sound like a drive failure. Does it have a recovery partition? Try booting with COMMAND-R held down see if it boots there, maybe that part of the drive is still functional and Disk Utility can do some repairs...

But honestly, I would contact the seller or manufacturer and see about a warranty replacement.
