Hi!
I have strange problem with my disk. Extended offline SMART test is Completed always without error but Short offline SMART test is showing Completed: read failure. And the LBA of first Error shows: 625152530. But the mediasize in sectors is 625142448. So it looks like it reporting error in LBA outside the disk drive. I tried MHDD and it doesing find any bad sector on disk. (as it scans from 0 to 625142448). Do you know how to recover from this ?
