Re: how to rescue this backup data

Hi,

The kernel does find the most recent session on
DVD and mounts it by default.
So  -t iso9660  might well be the way to easily
mount the DVD+Rs in question.

What Linux cannot do easily on DVD is finding
sessions other than the first (by sbsector=0) and
the last one (by no option sbsector=).


More errata:

Should have been "with DVD".

Should have been "mount ... '/dev/sr0' ..."
(I tested the command with DVD-RW at sr2 and
 copied the outcome.)


Have a nice day :)
