Disc Fail Resync Question
Happy Thanksgiving. I have (2) 4 TB discs in my unit. The admin page showed the "disc state" for the disc 2 as having failed. I decided that I should reboot the unit and make sure it wasn't som...

I see 1963 reallocated sectors and after well over 24 hours the resync is only 1.74% complete.
I generally replace disks before they reach 50 reallocated sectors, so I think it is a bad disk.
You can check warranty status and execute the return from WDC's web page. If you are in the US, they offer a service to send you the replacement first, with a return label. It's a reasonable deal, and is the fastest way to get the replacement.

Does this mean the disc likely isn't bad after all, pending a successful resync? Has anyone ever seen a drive show up as failed, only to have it require a resync on reboot?
Certainly something bad happened related to that disk. I agree with Sandshark that you should look at the SMART stats. If it were my disk, I'd pull it and and test it in a PC with vendor tools (seatools for seagate, lifeguard for western digital). I'd include the destructive write-zeros test, because I've found that it will sometimes detect issues that the non-destructive tests miss.
I wouldn't assume that all is well, even if the system does successfully resync.
Thanks both of you. I don't know a lot about hard drives but looking at the stats I suspect something is very wrong with the disc even though it is trying to resync. I see 1963 reallocated sectors and after well over 24 hours the resync is only 1.74% complete. I am going to make sure I have a backup and get on the phone with WD and try to get a replacement, I bought commerical drives and I believe it should still be under warranty.

Thanks again, good info, I'm signing up for the advance replacement.
