I am using Windows 7 64-bit. I have Hard Disk Sentinel installed and it gave a bad sector warning for My Book Studio II 2 TB twice in one week. I ran Windows Check Disk and it found no errors. Then I ran Data Lifeguard Diagnostic for Windows extended test and got this message (partial message shown):
… Test Result: FAIL
Test Error Code: 08 - Too many bad sectors detected
I contacted Western Digital and opened a case. They recommended running Windows Check Disk to correct the problem. Either Check Disk can’t find the problems or the extended test and Hard Disk Sentinel are incorrectly showing problems. Before I go back to Western Digital does anyone have any ideas about this?
