Is hard-disk really dead?
Hi guys, I have a Readynas Pro 6 with 6x Hitachi 7K3000 2TB Drives. It's only been running for about 2 weeks & I've been mostly happy with it. It's running with X-RAID dual redundancy. From the ve...
Think I may have had this issue too.
First disk to become 'Dead' had one smart error: Offline Uncorrectable 1. So I let it slide.
Second disk to fail seems to have no smart errors but I'm guessing a disk can have no errors and still fail.
When the first disk failed I replaced it with a new one. Afterwards I decided to add back in the failing disk to see what would happen. It resynced and expanded and has been working away solid for nearly 2 months...
Last week then the 2nd disk failed. I only got around to it today but I just rebooted the nas and it started a resync and hasn't reported a problem so far.
First disk to fail was in slot 3 which I moved to 6. 2nd disk is in slot 4 and hasn't been moved, so it doesn't seem to be a slot specific problem at least.
I think I ran a firmware update shortly before disks started failing. I could be wrong there though because I see no mention of a firmware update in the logs. Unless that sort of thing isn't logged?
