Well my guess would be that there is a CRC error on your HDD (as it states), you could format it, install Linux again, and hope that it works. I don't know for sure, but it looks like the CRC's on your bootsector... FDISK /MBR could also do the trick... I don't know if there's such a command as format /mbr...
It can be either physical error (scratch (hope not)) or just magnetic, which should come clean off when formatted (usually)... Hopefully this is of any help...
