So I have a Qnap TS-873A with a number of different Seagate and WD drives varying from 4 months to 60 months old.
I previously had an IronWolf 8TB show some SMART errors ( I can't remember what ones exactly ) but the errors went away when I pulled the drive and ran a full badblocks pass and additional SMART tests. I still RMA'ed that drive though as I'd started the process before the tests completed.
Now, I have another IronWolf 8TB that has shown errors a few times. Here's a timeline:
- Unrecoverable Read Error at 11800 hours, which triggered a disk replacement with my enclosure spare.
- Pulled disk ran full badblocks pass and smart tests. Everything came back as have no issues.
- Swapped this disk back with enclosure spare and rebuilt RAID array.
- Same 8TB disk shows Unrecoverable Sector Count and Current Pending Sector as 1 (raw value 100) and triggers another RAID disk swap and rebuild.
- I'm waiting for the rebuild to run another badblocks scan but when I logon today I see that the same drive is showing another Unrecoverable Read Error.
- In addition to this new error is now shows no Unrecoverable Sector Count and Current Pending Sector errors. The SMART test is clean.
Is this flip-flopping usual for SMART test results? The rebuilds are getting tiresome, especially when they seem to be for nothing...maybe I should make the spare a cold spare, rather than a hot spare.
Anyone have any other suggestions?
On a side note, I have one other IronWolf 8TB, same model, that has given me SMART errors that miraculously disappeared as well. Is this just a "feature" of this model? That makes it 3 out of the 4 ST8000VN004-3CP101 drives I've had that show these same annoying symptoms but the only one that hasn't is still pretty new (the RMA replacement).
