Do you know how much data in these folders?
Try to copy these folders to some other place, then copy back. After that try to run the scrub again.
If you want to migrate to a new disk, you may use this instruction:
You did not say that you use Unraid. It supports formatting to xfs by default and mounting of ext4 disk, so for Unraid you seems may format either to xfs or to zfs. zfs is a good choice, but without redundancy (parity or mirroring) it cannot resist corruption and is slower than xfs and ext4. If you don’t use zfs features, you might be better off using xfs.
you need to run the command
please note the --force flag - it will remove data. This command will exit, when it finish its work.
