MB won't boot - Hard Drive damaged?

Hi,

I have a problem, my Macbook Pro 13" (2012) i5, does not boot.
I gives a grey loading bar and when it is completed the mac shuts down again, this is in normal and safe mode.
I've tried to clean the NVRAM, but no results.

I can boot the mac with cmd + R, but when I verify/repair/erase/partition the HD, it gives several errors. Like, can't (un)mount disk.

With single user mode (cmd + S) it says:

Incorrect number of thread records (4, 31103)

Can some please help me try to solve this problem or give me things to try.

Thanks in advance,

LTKort

PS I have a back up on my TimeMachine, so I do not mind if I erase my HD.

MacBook Pro, OS X Mavericks (10.9.2)

Use fsck if necessary

if throught single user mode you can repair your disk,

you are going to have to reformate the volume through Recovery. This wipes the drive and you start over.

Verify SMART status

I've tried fsck a few times, I still get "the volume was modified".

And what do you mean with verify SMART status?

Your option seems to be boot into Recovery.

SMART is built into the HD itself.

Disk Utility- Select your upper most HD it will tell you is verified SMART status. or failed.

If you do not pass SMART status your drive needs to be replaced ASAP

If verified you can proceed:

You can try reformating the drive, Partition 1, GUID, extended journaled.

A backup is a must, formating the drive you lose all data and OS.

Reinstall the OS from recovery.
