What do these errors mean? Is it OK to use this drive or should I replace it? Is my data safe? I'm not sure but I think "at disk power-on lifetime: 15540 hours (647 days + 12 hours)" I was deleting files from this HDD (don't know if that even matters).

 

Please advise.

Replace asap. Then can run a preclear on it to see if it will still run safely.

Check warranty and rma if possible (and failed preclear)

Your disk reported a "media error" (UNC Error)  Basically, a sector where the data on it did not match the checksum at the end of that same sector.  It tried multiple times to read it, but failed.  It eventually reported the "read" failure to unRAID.

 

That resulted in the "read stripe error"

 

unRAID, in response, read all your other disks and re-constructed the data that was on the bad sector.  That was then used in your file deletion operation to keep the directory entries correct. 

 

In addition, that same correct data was written to the un-readable sector.  That seems to have been re-written, in place, and was successful by the disk.  (It would have marked the sector as pending re-allocation, but your SMART report shows no sectors as pending re-allocation, nor any re-allocated.)

 

Basically, the issue is corrected.    Keep an eye out for future errors.    Run a non-correcting parity check.  It should find and fix any additional un-readable sectors.  I do not think the disk needs to be replaced.  The "short" test you performed completed without errors.

Thank you both!

 

I'll watch this drive closely and as soon as get some money I'll buy replacement and preclear the old one at least 3 times to check if I can keep using it in my unRAID.
