Repeated failures of Disk 6

[shimee]

Hi All,

I am experiencing repeated failures of Disk 6 in my array. Initially I thought it was a one off, and several months back replaced the drive. Been running OK for almost 2 months on the new drive then it also failed. I replaced it with a new 6TB WD Red about 2 weeks ago, precleared and installed and was all ok but now it also displays the Red X.

 

This particular drive is one of 4 Connected to my Supermicro SAS>SATA Card. Along the way I have checked and replaced the cable, now I'm thinking it must be the Card that is at fault. Seems a little bit odd, before I try swapping that out, could there be anything software related in unRAID that I should be checking first?

 

I attached a diagnostics from prior to the drive failing and also one from now that it has failed.

 

Thanks all

It might be the controller as they are known to drop disks, but since the disk dropped offline there's no SMART report, reboot and post new diags.
