Hi,
Actually I was asking the same. whether it is possible to edit the
inode content of a disk or the image of a disk. Did you mean that it
is not possible at all. Is there any method to edit the inode content
and use the edited inode for a file, If we can ensure high care.
because such a method will be the most robust one in the recovery of
deleted file.
Regards
ranju.
