RAID lets me copy but not change

I have a Terra Master DS-300 USB 3.1 five bay drive. Bought 10 June 2018.
Five 4TB drives in RAID configuration.
Connected to a MacMini running 10.15.7 Catalina with 32MB RAM
The unit has worked well until the other day.
I get an error message 'mac OS can't repair the disk Raid' basically I can open and copy files but changes can't be saved. It suggests backing up and reformatting.
I have backed up but do I need to reformat or is there a quicker fix?
