Rejection of CDs of other users
In environments where you don't have direct control over
the network CD writer it can happen that
-
someone else puts in a CD while webCDwriter is waiting for your CD
-
someone closes the tray with your CD just burned while webCDwriter
is waiting for the CD of the next user
To avoid at least the mixing of private data of two users
on one CD webCDwriter writes a user ID to the "preparer ID" field
of the ISO9660 filesystem. Before writing to a medium webCDwriter
looks for a user ID and asks you, if this ID does not match yours.
