Reading a sector from 2nd session of a CD-ROM

NTDEV
1

I have posted this on ntfsd with no luck; I hope
someone here (maybe microsoft people) can help me…

Why I cannot read sectors of second session of a
multi-session CD-ROM using the method described in the
MSDN KB138434? Any suggestions?

Also, I have tried IOCTL_CDROM_RAW_READ, and it works
fine on some machines, but when I try exactly the same
code on my new laptop with a DVD burner / WinXP Home
Ed., it fails. Any hints?

Thanks in advance,

Farshid Mossaiby

Could you please define “fails”? Does it give you an error? Does it give you the wrong data? Does it give you no data?

Thanks,

Thanks for your reply.

GetLastError() returns 0, and no error is reported,
but BytesRead = 0 and no data is returned.

Thanks again,
