HDD boot and formatting failure
My Macbook does not boot, recovery partition does not boot either.
I have a Mavericks USB I made. When I try to format my drive in an attempt to do a clean install to see if it is a software failure, Disk Utility either gives a "couldn't format, backup data" error or halfway formatting, drive disappears from list.
"Quick test" of Apple Hardware Test gives out a "4SNS/40000000:Th1H-82.625" error code, though "extended test" does not report any errors. Code relates to a sensor error, but I'm not sure.
What it it? What can I do further?
Thanks in advance.
