Hello,
i'm looking for a tool independant of the file system that allows me to
obtain an image of a block device.
Does this kind of tool exist?
I use reiserfs, and i have a tool called debugreiserfs but it only takes
in account used blocks.
Bye .

If you just want to know if the contents of the two entire block devices
are the same, you can use md5sum on them and compare the result.
