Hi,

 

I recently physically moved my server into a cabinet and upon starting it it ran into troubles with one drive.  When checked, unraid reported 160mil writes which seemed quite odd as it wasn't running for long and I wasn't writing to the array.  I stopped the array, shutdown (neglecting to take the log, bad me) and checked the connections.  Everything seemed ok.  After restarting the array, unraid took the drive offline and smartctl now shows it as having a Calibration Retry Count of 1 (raw value)on disk 1 (Samsung F1 750GB) with a log of the event yet still shows its status as health status as passed.

 

I have ran the drive through the smart short/long tests and checking the results after completing and no changes to any of the normal attributes (relocated sector, spin up retry, etc) were changed.  Since its only holding movies I figured I would try my luck and have unraid rebuild the contents from parity (unassign, reassign slot).  No real changes from smartctl and unraid seems to take the drive just fine.  I haven't written any data to the array yet as I am still unsure what can  result from having a calibration being retried.  Reading the data off the disk seems to check out normally. Anyone able to chime in with more information on this attribute?

 

 

I checked all of the SMART reports I could find, and found that only Samsung, Western Digital, and older Maxtor's actually use the Calibration Retry Count, and only Samsung had anything but zero.  I found only 2 reports here, with the same value of 1, and their VALUE and WORST were still 100, as I suspect yours is, so there appears to be nothing at all extraordinary about it.  I would say ignore it completely.

 

With apologies, I'm not used to your terminology, I don't know what "160mil writes" means, or where you saw it.

That's pretty close to the same that I have found as well, while going through the typical search engines and this site as well.  Thanks for the reassurance.

 

As for 160mil, that was a  bad abbreviation choice on my part.  I should use M or say 160,000,000 writes.  The writes had me concerned but so far all the movies I have checked (from varying dates when added to the disk and other disks) seem to be intact.
