OK, this makes no sense whatsoever. In the first pass, it complained
about the root inode being corrupted; that's fine, that was probably
from the initial hardware corruption.
The second time you ran e2fsck, it didn't complain about anything
until pass #5, so apparently the root inode was OK the second time
around. But when you run e2fsck with -n, it opens the device
read-only, so theres no way the filesystem could have changed.
If you didn't run any other commands or do anything else between the
two runs of e2fsck, then you have some serious hardware problem where
the disk is not returning the same data between the first and second
e2fsck run. And if you have wierd hardware problems, either with the
hard drive or how the hard drive is connected to the OS, there's
really nothing e2fsck can do to help you.....
