...which works like a CD-Rom emulator on your hard drive? If my understanding is correct, it's a portion of a specific CD burning software. As such, it's possible that the software needs to be updated to "recognize" the new Sony drive...I believe the link below should help:

I run windows xp service pack 1. The problem is that the machine has a sony dvd rom and vobid cd rom, I recently installed a sony dvd rom with cdr/rw thinking i would be able to copy audio and data cds, and now the system does not recognise the vobid drive and consequently audio cds do not play, data cds will load but the vobid drive letter is still not shown in my computer.
