Power Flicker killed drive?

Featured Replies

My UPS battery died this weekend and we hadn't had a power outage in 7 months so of course when I plugged in my server without the UPS so I could use it over the weekend before my new batteries arrived the power flickers just enough to reboot my server.  Now my newest drive (6 months WD red 3TB) has a red X.  Ran Smart reports (long version) came back clean so I decided to try rebuilding the drive.  27 hours later the message said Data Rebuild completed with 0 errors and then the next entry is "Disk 5 in error state (disk dsbl)"

 

attaching the last test I have. Currently running a new long test.  Is this drive likely dead?

Finished a new Long Test overnight.  Haven't had a chance to see if it has anything new but wanted to post this before I left for work.

Extended SMART test completed without error, still believe that this disk is not very healthy, you could try using it on another server (if you have one) or in the same server but trading cables and controller/enclosure with another disk, if the same disk fails again in the future then you can be sure it's bad.

  • Author

I paid the taxes to buy a new disc locally to replace this one with the intent of running a pre-clear on it after I get the new one pre-cleared and rebuilt.  If that comes back with issues I will start the warranty process.  If not I, I do have a pro license and I'm only currently at 9 disk so I can try it.

 

Thanks for the help so far.

Just my opinion, but I think the drive is fine.  All of the visible errors are just device faults from 47 hours ago, rather unusual, but probably just issues with the bad power incident.  There's no other evidence of anything physically wrong with the drive.  And the faults haven't occurred since, so probably the drive was fine once rebooted.

The issue is that after two reboots and a rebuild I still can't get unraid to not report it as faulty and enable it.

So the drive is unmountable?

Rebuilding an unmountable drive won't make it mountable if e.g. there's a file system corruption. Wait for one of our experts to tell you what to do next.

So the rebuild completed successfully but the disk was disabled right after?

 

If you still have it post the syslog that includes the rebuild.

  • Author

I bought a new drive and pre-cleared it and rebuilt Drive 5 on the new drive.  I then Pre-cleared the offending drive with full test and it completed with no errors.  I ran the SMART Short test which came back without errors.  Before I start a SMART extended test is there anything else I should do to check this drive so I can feel comfortable adding it back in?

 

 

By the way thanks again to everyone for the help.

Didn't see your post in time but I imagine pre clearing a drive and adding it in as a new drive would probably take care of this issue, correct?
