Hi Theresa
This topic has been discussed in the past and I did use a method for=20
burning multi-sessions described by The X Lab; I used the method once=20
to see how it worked and, although a bit messy, it worked according to=20=
their instructions!!
If you want to try it see:
<http://www.thexlab.com/faqs/multisessioncds.html>
After that, someone pointed out that with blanks being so cheap now it=20=
was hardly worth the effort if it is only being used for backups -=20
however it probably depends on how much and how often you want to=20
backup! If it is only a small item with frequent backups, I would use=20=
my zip drive!! It's up to you!!
All the best
Paul
