Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 595 - I suspect since the smart tests are showing no errors, that the issue is with the drive dock or cabling. I am using a internal/external SATA bracket, and not receiving any errors on the internal drives so I don't suspect it's a controller issue with the on board SATA III controller. The current drive dock and cables are SATA II, I have since upgraded to SATA III 2TB drives since it was purchased along with 1TB SATA II drives. So I have been considering purchasing a new SATA III dock and cables anyways, but just in case I need to spend the money somewhere else to fix this issue I just wanted to see if anyone else had any other ideas on what might cause this scenario. -- Thanks, Dean E.
