Please see the response StephenB gave to your other posting Hard-Drive-Freezes-up-during-backup-ufsdapi-file-flush-365 .

Unfortunately, when the mods moved that message to the proper area, they did so in such a way that normal users cannot respond to it.

Here's what I posted there (just to keep things consolidated):

You selected "4200" for the model - which is a rackmount model. But ReadyNAS 4Plus sounds like you might mean a 4-bay Ultra Plus. Can you clarify exactly what you have? Also, let us know what firmware you are running.

Generally this type of error on the LCD means that the NAS crashed at that location.

I'd start by testing the USB disk in a windows PC, as UFSD is the Paragon driver that some NAS models use to write to USB drives.

It was difficult to use the Bulletine Board and find any NAS listed in my original search.

I have ReadyNAS Ultra 4 Plus with 3 8tb Ironwolf drives, and 1 4 tb HD
Firmware 6.10.3

Freezes up during backup with only 1 share folder, the other ones work.
I ran a virus and malware scan on the drive but still get the error and crash.

  It has nothing to do with malware or virus. Either there is a problem with the USB drive (or the file system on it), or there is something seriously wrong with the RAID volume in the NAS. You need to figure out which, and then take the appropriate course of action to resolve it.
  
  The suggestion was to actually test the USB drive. For instance, using Seatools (for a Seagate disk) or Lifeguard (for a Western Digital disk). Run the long generic test at least. That will read every sector on the drive.
  
  The other thing to check is that you can access all the files in the share. You can do that by backing up the share to another USB drive, or copying it with drag and drop. If you have enough free space in the NAS, you can also create a temporary share, and set up a backup job to copy the problem share to the temporary one.
  
  Looking in the full NAS zip file for disk-related or file-system related errors would also help figure it out.
