this is true. yet, saying dvd distinguishes cd from dvd. plus, i would
use *optical disc storage medium* instead of _devices_ for better
description, and call what they are accessed in _devices_. :=)

agreed. i have 3 different releases of dd-rescue that i will be using
to try to recover boot tracks of 3 hdd's that that an attempted install
of fedora 17 corrupted when i tried to install it. format instructions
where pp, to be terse.
i did make a 'dd' of each hdd's boot track. problem is that i was
distracted before i copied them off to usb memory. and did not. :=(
i also have releases of sysrescuecd, photorec, and another recovery
prog that idnrc at this time.
if you have some advice on such, i would greatly appreciate.
you can write me _off_list_ or start a _new_thread_ so as not to ravel
this thread.
later.
