Instead of looking for the volume descriptors at offset 32768 (block number 16 on a CD) from the start of the disc, it shall start reading from the 16th block starting in the first track of the last session. Block numbers forms a contiguous sequence starting at the first session, continuing over added sessions and their gaps. Hence, if a CD mastering program wants to add a single file to a CD-R containing a ISO 9660 volume, it has to append a session containing at most an updated copy of the entire directory tree, plus the new file. The duplicated directory entries can still reference the data files in the previous session(s). In a similar way, file data can be updated or even removed. Removal is, however, only virtual: The removed content does not appear any more in the directory shown to the user, but it can still be recovered as it's still available on the disc.

Grundsätzlich sollte also das zuvor schreibende Gerät und Betriebssystem mit den Disks zurechtkommen.
Falls die Info noch nix nützt:
Mit
isobuster lassen sich die Daten höchstwahrscheinlich dennoch retten.
