That file looks ok, this is very weird…
Let’s scan hard disk, maybe this is hardware problem.
Download MHDD utility from here:
MHDD download link
Unpack and burn as ISO …
Add and boot MHDD from disk ( in the same way as Live CD )
[*] When you load the file select option 1
[*] When the menu appears, select the disk that you’ll scan
Type in:
scan
…and hit enter
[*]In the next menu, click F4
[*]It will begin HDD scanning, allow him to finish scan.
If there is more than 3 inputs in the district UNC X then your hard disk is damaged.
