man fsck says:
The exit code returned by fsck is the sum of the following
conditions:
0 No errors
1 Filesystem errors corrected
2 System should be rebooted
4 Filesystem errors left uncorrected
8 Operational error
16 Usage or syntax error
32 Checking canceled by user request
128 Shared-library error
so zero means no errors without our having to guess (however, it implies
that it did a check, but we're assuming that, so there is a guess there).
You could try the '-r' option to fsck and it will tell you the return
code and some other stuff, supposedly.
Anyway, it would REALLY HELP to know what 'df -h' says. That would
answer (most of) the questions I still have at this moment.
Oh, how big is the USB stick? How much room is left?
and what does 'sudo fdisk -l /dev/sdb' say?
