I have a drive that is reporting bad in UNRAID (red dot). I first noticed it yesterday and did a parity check and it came back good. However the red dot is back today.

 

I have run a SMARTCTL report from the WIKI, does this drive look like it is dying/dead?

 

Thanks

 

Ridley

That drive looks fine.  I would look at some other common causes:

 

[*]power cable to the drive, if you are using power splitters these can sometimes break down and become troublesome

[*]SATA cable to the drive, make sure it is well seated, if it is loose you could swap it for another cable

[*]total power supply: are you running a lot of drives?  Power supply capacity can be exceeded in some cases long before the full power supply rating is hit, tell us what model/brand of power supply you have and how many (and type) of drives you have

 

Also, have you done any work on your system recently (added drives, moved cables...)?

I agree, it could be power related...  (or power cabling)  (or power supply) ( or power splitter)  (or drive backplane)  (or drive caddy)

 

The disk heads have been emergency retracted 11 times as a result of a power loss.
