fsck after recovery, journal seems to be wrong

[Erich Dollansky]

Hi,

my machine rebooted last night while doing a backup and formating a
device.

Ok, can happen, but the difference between an fsck useing the journal
and a full fsck without using the journal surprises me a bit.

While fsck with the journal showed no error, a full fsck came to this
result:

I did not realise any damage until just now when I found one file
missing. This made me doing the fsckes. 

At the end, I also found the missing file under a different name in the
proper directory. It could have been that the machine crashed while
kate was trying to save this file and left it with the extention
cppgh6857.new. It seems that nothing is missing from the file.
