Mount and tune2fs disagree

[shmuel siegel]

If I run 
mount /dev/hda1 /mnt 
I get a 32 megabyte file system using 6 meg but neither ls nor du find
any files.

both tune2fs and e2fsck think that it is a 273 megabyte partition and
e2fsck says that the file system is okay. In fact e2fsck says that there
are 3 directories and 90 regular files.

We will assume that I messed up my drive somehow when I installed fc2 t2
on a partition magic formatted drive. (I got the usual warning about the
disk parameters). I also did other things later which probably didn't
help and therefore it is too late to resolve the cause of the problem.
The real questions are
1) why are the two methods producing different results
2) how can I recover my data
3) what information would I need in order to file a useful bug report
