Hi @Wdw ----- Thank you again for your patience here while our team has been performing some in house testing using the information you have provided to us.
Moving forward, we have setup a similar configuration to your and thus far have not run into any issues while trying to delete previously created backups (or restoring from them as well). Here are the steps we followed:
- formatted a 32gb flash drive FAT32
- plugged it into ROCK
- made a backup
- shut down rock and removed the flash drive
- plugged flash drive into Mac
- confirmed i can restore from the empty folder
- deleted the “empty” folder
Based on the above, is there anything we may have missed in our steps in comparison to your “work flow”? Furthermore, do you know what the mentioned flash drives are/were formatted to?
