This is the preclear finish file. I don't see anywhere that it says the disk was cleared but I can't tellt hat it is failing either. Can you guys comment?

This is the preclear rpt file. Here it says it was cleared, but I don't understand what it means that so many sectors we pending re-allocation. Haven't had a drive do that yet.

155 sectors were pending re-allocation before the start of the preclear.

155 sectors were pending re-allocation after pre-read in cycle 1 of 1.

141 sectors were pending re-allocation after zero of disk in cycle 1 of 1.

141 sectors are pending re-allocation at the end of the preclear,

    a change of -14 in the number of sectors pending re-allocation.

0 sectors had been re-allocated before the start of the preclear.

0 sectors are re-allocated at the end of the preclear,

    the number of sectors re-allocated did not change.

============================================================================

 

 

I'd run another preclear cycle and see what the results are. My gut instinct says the drive is failing sooner rather than later. I definitely wouldn't trust it in an array until you get the pending sectors down to zero, and maybe not even then.

 

All drives eventually fail, it's just a matter of when.

So what is important to look at here? Pending sectors? Could you explain what that means as well please? Thanks

  • Author

Ran the preclear again and got same results. The drive passed the preclear.

 

All numbers were same except now all of them say 141 sectors were pending re-allocation were as in the first test the first two lines said 151 were pending.

 

At the end it says 0 had been re-allocated...

 

What does this mean?

Should I throughout the drive? I thought the most important part to pay attention was whether the drive passed preclear or not.

Don't use the drive in unRAID.    RMA it. 

No drive should ever have sectors marked as pending after a preclear.  They should all have been re-allocated when the disk was written to.  The only way your issue can happen is if they are again un-readable in the post-read phase.
