>From the loop, doing:

e2fsck -b 8193 /dev/hda2

gives:

--------------------------------------------------------
e2fsck: Attemp to read block from filesystem resulted in
        short read while trying to open /dev/hda2
could be a zero-lenght partition ?        
---------------------------------------------------------

but fdisk gives the correct size for hda2.

I think the problem began after I mounted the loop to hda2,
and ended the sesion without unmounting it.

Luckily, I have a nearly identical loop copy of the hda2 files, so I 
will format again hda2 and transfer the loop to hda2 with Steven 
script.

Alejandro.
