yesterday i burned 4.2 G onto a DVD using OS9 and toast 5.2 on my 933 G4
with the built-in pioneer drive.

today, i already have to access some of this backed up info.

the DVD doesn't show up on the desktop.

according to toast, there is a DVD-ROM in the drive, to which i cannot
write, but that is the extent of the information i can retrieve.

any clues?
