In my experience, fsck on flash/sd always ends in tears. It was disabled until cssu, then enabled and wrecking partitions, then disabled again, and now I don't know if it's armed to nuke /home or not.

Anyway, my usual strategy after unexpected reboot, is to do as root:
cd /home
ls -laR >/dev/null

fs errors usually show up with that. If the damage is sma, I've made tarball of /home in backupmenu, then recreated fs and untarred.

If there are non-fs issues, like zeroed files, they wont be found by this.


Good luck!
