Great stuff. Thanks. OK, using your command but changing it to the
drive itself I got this:
~ # isoinfo -d dev=/dev/hdb

I then used dd to make a file:
~ # dd if=/dev/hdb of=FreeDOS.iso
dd: reading `/dev/hdb': Input/output error
313568+0 records in
313568+0 records out

I don't like the Input/Output error message but it did create a file
which gives the same info using isoinfo:
~ # isoinfo -d -i FreeDOS.iso

Now, how does one turn this ISO image back into a set of files and
folders to be changed and later turned back into an ISO image?
I see Joerg Schilling has responded. That's a famous name in this
area. Off to read his pages!
