Hi All,
I write a virtual CD-ROM supported by an image file via responsing
IOCTL_CDROM_… series in NT 4.0. But so surprise to see I cannot mount the
CD-ROM. VPB’s deviceobject pointer is always zero. IRP_MJ_READ is never
called. I notice that IOCTL_CDROM_CHECK_VERIFY has many info about media
change. But the DDK document is so confusing: VPB_MOUNTED,
STATUS_VERIFY_REQUIRED, DO_VERIFY_VOLUME, etc. I cannot make it clear.
Can anyone give me a clue?
Thanks a lot.
Jeffrey Ren
