How to stop Nero Write DVD by using minifilter driver?

Hi, everyone.I am developing a minifilter driver.The main function is control DVD/CD for ReadOnly or WriteOnly. i find when nero burning data to DVD,in PreWrite,it seems nothing happened.so can i know whether it is opened with "write" in PreCreate? if(Data->Iopb->Parameters.Create.Options>>24) & 0x000000ff) == FILE_OVERWRITE_IF)|| FlagOn(Data->Iopb->Parameters.Create.SecurityContext->DesiredAccess, GENERIC_WRITE) i think it is a write request, do i miss something? I know Nero write data to DVD through SCSI protocal,but I don't know how to stop it write. Could help me solve this problem? any advice is appreciate,thanks very much.

> I know Nero write data to DVD through SCSI protocal,but I don't know how to stop it write. Patch the "read configuration" SCSI MMC requests to always say that the media in the drive is non-writable. -- Maxim S. Shatskih Windows DDK MVP xxxxx@storagecraft.com http://www.storagecraft.com

hi maxim,i hava a idea about this, if it is not EXPLORER.EXE to get the disk letter information,then i always hide the CDROM.so all burning softwares can't find the cdrom and i can get my goal. now i wanna know how to hide cdrom in minifilter,it can be done?
