This is probably a super dumb question but I'm not sure if I'm reading this report right. Is this hard drive failed? In one part of the test, it says passed, but in a later part, it seems to say that it's failed twice.

 

Thank you.

Selective self-test flags (0x0):

  After scanning selected spans, do NOT read-scan remainder of disk.

If Selective self-test is pending on power-up, resume after 0 minute delay.

One thing I noticed is that there are Pending sectors - and unless they can be cleared then the drive is unsuitable for use with unRAID.  I am not sure if pending sectors can make the short SMART test fail.

 

I would suggest running a pre_clear cycle against the drive to see if the pending sectors get cleared.

Ok, I ran the preclear which only took 41 minutes (?) that doesn't seem right.

 

Here's what I got:

Thanks again for looking.

Something is definitely wrong.  You should not get error messages from the script if it is working correctly.

Download the latest version of preclear script. The one you have is broken.

I am using 1.15 from here (Pretty sure, I'm at work now and can't check but 99%) - is there a newer one?

I wouldn't trust the drive with that many pending sectors personally.

Ok, I got a replacement 3TB which just arrived and I've set it to do 3 passes with preclear & screen.

 

While that happens, is it safe to use the server - i.e watch movies off it, etc while 1 disk is missing? Or should I take the array offline?

 

Thank you again for the assistance.

The missing disk will be emulated using the other array drives plus parity. However, you would be running unprotected and a 2nd drive failure would result in the loss of both.
