How broken is my drive?

TrueNAS General
1

  • I could not get it to complete a smart test at first

  • Ran badblocks (0/0/8192 errors)

  • After badblocks it passed a short and long smart test

Are the bad sectors fixed and the drive is usable for a little while more?
Are the errors real bad errors?

I don’t know how you arrive at this conclusion…
UDMA CRC errors rather point to cables and/or controller, and a quick search suggests that the drive is CMR. Seems fine to me, although way too small.

These errors are not great:
187 Reported_Uncorrect 0x0032 001 001 000 Old_age Always - 507

Going by Backblaze’s interpretation, 187 is a common sign to a failing drive.

There’s also the history of the failed long SMART tests. The last one went okay but what happened during the previous 4 + failed conveyance test?

Drive looks dodgy to me, I recommend you monitor the numbers to see if they continue to go up and get a replacement strategy in place.

My guess, with very limited understanding, is that the bad sectors/blocks/parts of the drive did not get corrected or replaced until badblocks tried to write data to them, and that that is why the previous smart tests failed and the latest (after badblocks) passed.

Thanks for your advice, will monitor!

I would say that the drive is fine and as @etorix said, the UDMA_CRC Errors are likely a cable. However if those are not incrementing, the problem is likely an old one.

Note that the issue ID 187 is an old_age identified value, not pre-failure. You have no failure indications.

To address the SMART Test failures… Typically if you have a few failures (especially Extended test failures), these do not go away but in your case they did. Sounds crazy. I would advise you to run a weekly Long/Extended test and daily Short tests. Keep an eye on the drive and if the errors scroll off the list (meaning you have passes) then just keep running those tests. It is only just under 9 hours to run a Long test, well worth it.

An alternative option. Leave those test failures on the drive, RMA the drive.

thanks for your input!

will schedule weekly tests

it long out of warranty, kind of hoping it will fail so I need to buy a bigger drive, or you know, a few of them :upside_down_face:

Do not wait for actual failure, risk to your data, and the need to act in emergency. Get and burn-in new drives as you find opportunities.

9

Well since you put it that way…

Those SMART long/extended tests are hard failures, this drive should be replaced before it fails completely. And do not forget the other drives in your system which may be that old as well. :joy:

In all seriousness :clown_face:, I am surprised that the extended tests started to pass, I have never seen that before, not like what your drive shows. I really would replace that drive if you already had some plans to replace them anyway. As @etorix said above, don’t wait. Do it on your schedule, do not wait for a complete failure, it is never enjoyable when that happens.
