Popped in an old drive which I thought I would use as a cache drive. However when running preclear I got the following results which I assume means the drive is bad.
= unRAID server Pre-Clear disk /dev/sde
= cycle 1 of 1
= Disk Pre-Clear-Read completed DONE
= Step 1 of 10 - Copying zeros to first 2048k bytes DONE
= Step 2 of 10 - Copying zeros to remainder of disk to clear it DONE
= Step 3 of 10 - Disk is now cleared from MBR onward. DONE
= Step 4 of 10 - Clearing MBR bytes for partition 2,3 & 4 DONE
= Step 5 of 10 - Clearing MBR code area DONE
= Step 6 of 10 - Setting MBR signature bytes DONE
= Step 7 of 10 - Setting partition 1 to precleared state DONE
= Step 8 of 10 - Notifying kernel we changed the partitioning DONE
= Step 9 of 10 - Creating the /dev/disk/by* entries DONE
= Step 10 of 10 - Testing if the clear has been successful. DONE
= Disk Post-Clear-Read completed DONE
Disk Temperature: 37C, Elapsed Time: 4:28:07
