Having problem with WD15EVDS drive, so I backed up all the data I could. There were several files that were unreadable. Once all files were backed up, I removed the partition, created a new NTFS partition in Windows 7 and formatted it. So far, so good. I ran the DLGDIAG Short Test and it passed. Now, I’m running the Extended Test and it has been running for 16 hours so far and is projecting to run for 688 more hours. It seems that the test is slowing down at various points, so I assume it is encountering bad sectors. However, do I really need to wait 688 more hours before I request an RMA to prove to WD that the drive is bad? Is there a log file updated while DLGDIAG is running, so I can see what problems the program has found so far and just use that as proof of the bad drive?
