Thanks to the following for help with CD-ROM reader problems

>From replies I got (including two "me too") I gathered the following :-

Older CD-ROM drives such as the Sun (Sony) drive (and RD-42/43 ?) do

not support multi-session CD-ROMs, nor does either Solaris or DU at

this time. The only solution currently is to buy a CD-ROM drive which

supports multi-session and software to drive it from a third party. It

seems that Solaris 2.5 and DU 4.0 "may" support multi-session but this

is not known for sure.
