IOCTL_CDROM_RAW_READ problems reading YellowMode2

NTFSD
1

Hi,

I am trying to read YellowMode2 sectors, and am having problems. I have
been able to successfully read CDDA sectors. Here is a code snippet

raw_info.DiskOffset.QuadPart = 2048 * 16;
raw_info.SectorCount = 1;
raw_info.TrackMode = YellowMode2;

nRetVal = DeviceIoControl(cdReadPtr->cdHandle,
IOCTL_CDROM_RAW_READ, &raw_info, sizeof(RAW_READ_INFO),
cdReadPtr->readBuffer, 1 * 2048,&dwNotUsed, NULL);

If fails with error code 87, invalid parameter

Regards,

Ceri

I think you must specify the entire sector length, not 2048. Check the
CD-ROM driver source in the DDK and see what it is expecting.
