Needed - a byte perfect image of an entire partition
Background:
I did my first Debian install with Jessie.
I then went on to multi-boot a variety of versions and preferences.
There was always an install of current "old-stable" present.
Current problem:
I intend to wipe everything from dev /sda and do a fresh install using
configurations and partitioning that I've discovered that meet my
individualist requirements.
Preserving content of most partitions can be done with Clonezilla.
However one partition was corrupted. I found some data retrieval tools
which recovered most, but not all, data. I want a byte perfect copy of
that partition such that in the future I can attempt to retrieve more data.
Suggestions?
TIA
