1 of my disks had a reallocated sector count going up and up so i got a brand new 8tb to replace a 4tb that passed 3 preclears. the drive 3 was rebuilding fine but disk 5 has had error counts. i stopped the rebuild, reconnected the cables for disk 5, started up unraid again, and same thing. i was in the process of replacing parity 1 but after removing that disk and replacing it, i didnt want to start that with disk 3 those errors so i just left that unassigned and adding it after. i thought maybe its a power issue so i just unplugged parity 1 and started rebuilding again but same issue. im unsure what the problem is now. its a brand new drive with no issues preclearing. i ordered more of them blue cables for the hba but dont know if thats the issue and i hate changing those because ill have to mess with 3 other drives that are working fine so with my luck it can bring up more problems. 

 

i have an unassigned 14tb that i was going to also add at the end of fixing the array. i was going to unplug it to free up more power and try again.  i can use it to replace a drive if needed and still have the 1st parity drive unused. unsure how to proceed.

It's not logged as a disk problem, I would recommend replacing both cables and trying again.
