I've cloned my sd card to an external usb SSD drive. All seemed to go well, and it behaves wonderfully.
But after a reboot, it is right back to what it was initially after the clone. Nothing I do is saved.
So its as if it is write only, but it is not. It confirms things are saved--and I can close and open the files to confirm this--but after a reboot, it is all gone.
I first noticed it trying to tweek config.txt
Repeated it with test files saved to desktop.
Rpi3 with a sandisk ssd plus, in a seagate usb3 exernal case (origianal 3tb conventional drive died).
Does anyone have any clues for troubleshooting this?
