What should I do to enumerate DVD device in my scsi miniport driver

Hi folks,

My virtual scsi miniport driver can work fine for a cdrom device. But
when it enumerate a DVD media, it cannot work. What should I do for it?

In my virtual scsi miniport driver, for cdrom device:
1, SCSI_INQUIRY, set inquiryData->DeviceType =
READ_ONLY_DIRECT_ACCESS_DEVICE for cdrom device.
2, SCSI_MODE_SENSE, set
ModeParmHeader->DeviceSpecificParameter|=MODE_DSP_WRITE_PROTECT for
cdrom device.
3, SCSI_READ_TOC,
PCDROM_TOC tocFull= (PCDROM_TOC)DataBuffer;
tocFull->Length[0] = 0;
tocFull->Length[1] = 10;
tocFull->FirstTrack = 1;
tocFull->LastTrack = 1;
tocFull->TrackData->Control = 0x4;
tocFull->TrackData->Adr = 0x1;
Srb->SrbStatus = SRB_STATUS_SUCCESS;

Anything I need to do for DVD device?

Thanks
Wayne

Have a look through the commits to my drivers for the last few months. I
had the same problem and I think it was a sector size issue. CD’s are
supposed to have a 2048 byte sector size, and while 512 seemed to work
up to a point, larger CD images (eg DVD’s) didn’t work.

Add DVD profile and feature to SCSIOP_GET_CONFIGURATION response.
Implement the operations in that feature list.
