Looks OK but I would probably do another preclear cycle. I like to see all zeros on mine.
I just finished pre-clearing for the second time. Here are the results, all zeroes :
================================================================== 1.15
= unRAID server Pre-Clear disk /dev/sdc
= cycle 1 of 1, partition start on sector 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 - Verifying if the MBR is cleared. DONE
= Disk Post-Clear-Read completed DONE
Disk Temperature: 40C, Elapsed Time: 61:53:15
========================================================================1.15
== WDCWD40EFRX-68WT0N0 WD-WCC4E2YR7DEH
== Disk /dev/sdc has been successfully precleared
== with a starting sector of 1

Thanks for your help!
