RAID5 QTS 4.3.4 and Single File Integrity Check and Repair

Hi all! I finally got around to upgrading from my TS-669 Pro, and copying files over (migrating) from my RAID5 Storage Space to the new NAS I’m finding a few individual files that won’t complete a copy (Error 0x8007003B) and appear to be corrupt. On the old NAS I utilized monthly storage space (Legacy Volume) scrubbing and weekly SMART testing but I know this old machine is suffering from hardware issues (Drive 2 Unknown SMART Errors).

QUESTION: Is there a QTS 4.3.4 GUI option or SSH command to attempt to recover or repair single files? I know there is a GUI command to “Check File System” but can individual files be checked for integrity and repaired?

Thanks all!
