I think I got some SD corruption by plugging one-too-many external (powered) USB drives into a Pi 3, (but not using a powered USB hub).
I am able to start-up and I can ssh into the device, but when I connect via RealVNC, I get a tiny screen back.
I am hoping that there's some way to rescue the card contents. I'd really appreciate it if anyone has any ideas what I can try next. (I have another Pi and a Mac that I can use if of any use.)
This is what I have tried:
Trying to recover the VNC connection, I tried running
to establish a virtual mode instance, but this resulted in an error:
xauth: error in locking authority file /home/pi/.Xauthority Error: could not run xauth
/home/pi/.Xauthority shows -rw------- (600)
If I try to do
I get an error:
chmod: changing permissions of 'xxx': Read-only file system
I have tried doing
sudo fsck.ext4 -v /dev/xxx
and then trying to find superblock backups with
sudo mke2fs -n /dev/xxx
but this doesn't find any backups.
