Reinitialize disk-drive

Can anybody tell me how to reinitialize my CD-drive?
When I burn a new session on a CD (there are existing some sessions on CD)
I can’t see my new files until I open and close my drive.
(the burning process set with flag NBF_DISABLE_EJECT)
I am using NeroAPI and WIN2000.
I know there is the Multimounter from Nero available, but it only works with the Nero Burning program itself.

Thanks for your help.
