My internal hard disk is 0 byte and a flashing question mark I have been striving to bring my laptop to life,
however, I am seeing a flashing question mark on my MacbookPro screen. 

I tried disk utility and it is just showing me Media and it is 0 byte. 

I ran DiskWarrior and it gave following error:
An unexpected error occurred while communicating with this hard drives built in S.M.A.R.T. diagnostics, error -536870210, 28260C-
I installed a new hard disk. Problem was my old harddisk died because of shakes.
