For the third time in about three weeks, a drive shows up as disabled in my unraid management interface--the same drive each time.  I've now RMA'd the drive twice and received a different Seagate model each time (but of the same capacity).  I know it's possible that I've just caught a string of bad luck, but the rest of the drives in my array are fine and they're all considerably older (and a mix of manufacturers).

 

I saw the onset of the death of this latest drive happen.  The number of reported writes went to nearly 3 billion and continued to climb at an alarming (and probably impossible) rate, even though I wasn't writing anything to the array.  I can start the array and the disk will spin up, report a temperature, mount, report free space left on the drive, and report a number of reads.

 

Is it possible that unraid is falsely reporting a dead drive?  Or is there something else I should be checking in to?

Have you tried the typical troubleshooting steps to rule out non-drive issues? Memtest, change cables, use different sata port, and then the drive SMART tests...

A string of three failed drives in the same slot could be coincidence, or not...

 

It could just as easily be:

  The power cable to the drive.

  A power splitter in line with the drive.

  The SATA cable to the drive.

  The disk controller port.

  A connector or back-plane that is intermittent.

 

unRAID does not "falsely" report a dead drive.  It will only take a drive out of service if a "write" to it fails.

 

You should get a smart" report on the drive now... and another if it is taken off line again.
