I made a backup of a bootable raspberry pi usb flash drive using disk utility on a mac. Apparently the disk image is corrupt and I no longer have the original USB flash drive. I have tried to see if I can fix the issue using TestDisk on my mac to no avail. I still have the contents of the flash drive (files) and also wanted to d=see if i could recreate the boot drive from these files

I am hoping someone can help me figure out if I can fix it and how. I appreciate any help I can get. Thanks!

Here are the testdisk errors found:

• Raspberry Pi 4 8GB
• Debian 11 (Bullseye)
• Working Wyoming-Satellite (past tense….)
