Re: Please How do I calculate the offset of a file within a ext3 partition

I need to understand and to calculate the offset of the beginning of a

Can I use dumpe2fs to figure that out, if yes how?

(Sorry for the duplicate William, forgot to reply to the list)

Not sure about dumpe2fs but you can use debugfs to do so. For example:

/sbin/debugfs <fs> -R "bmap /path/to/file 0"

Will give you the first physical block corresponding to logical block
0 of the file.
