Identifying a failing drive
Hi all,
I'm running an original NV with 3x1TB drives. In the last day or so, one of the drives has gotten pretty noisy - it sounds almost like a drive is constantly running and the normal noise that a running drive makes is much louder than usual. Problem is, I don't know which drive it is. RAIDAR shows no issues, the health checks in Frontview are OK. I rebooted and did a volume scan which had no errors. I'm thinking I'll go ahead and order a replacement drive since something weird is definitely going on.
Any suggestions on best way to ID the drive with the issue? If I power the NAS off, pop out drive 1, and power up.... everything will be OK, right? Then I can repeat this process with each drive to see which one is the culprit?
Any bets on which drive is the bad/failing/noisy one based on these SMART checks?

OK so the resync is normal then.
Is there a better way? Let it boot fully on 2 drives, shut down, re-add the 3rd drive while off?- If the drives become out of sync, a resync would be needed anyway. So not sure that would help here. Obviously too late for the first drive.
- I never followed up on this - I pulled each drive independently and none was the source of the noise, it must have been the fan? In any event, the unit quieted back down on its own and seems to be running normally again.
Side question - I still have the failed drive I pulled a couple months ago. Is there anything I should do in terms of data security before I trash it? Is it even possible for someone to extract useful data from 1 drive of a 3 drive NAS? Should I take a hammer to it just to be safe?
Thanks! - Your data wouldn't be able to be recovered just off that disk. Anyway, if you want and if the drive still kind of works (not completely dead) you could write zeroes to the start of the disk. That would be wipe the partition table off the disk. You could then format it with say NTFS and someone looking at the disk may think it was taken from a Windows machine rather than from a NAS.
Or zero the entire drive. WD lifeguard will do that (and that function is not limited to WDC disks).mdgm wrote: Your data wouldn't be able to be recovered just off that disk.
