https://support.microsoft.com/en-us/help/138434/how-win32-based-applications-read-cd-rom-sectors-in-windows-nt[^]

so this is the best example i could find, the goal is to determine sector size, 2048 may not last forever, and the number of sectors on the disk being scanned

i wanted to build a tool to check the low level condition of an optical disk below the error correction

cd has C1 and C2 error correction which is standardized so i would like to add a couple of functions the project

seems that auto detect the optical drive is obviated

definitely looks like i will have to dance around the miniport api to be able to do a basic read of a disk

do you know what api replaced mmsystem.h i used to use back with the early cd-rom?

What I have tried:

the old absolute read/write from DOS is not available for XP and above

mmsystem.h is another header i have used in the past

definitely looks like an uphill project

mmsystem.h make it easy to play wave audio and even a cd

but while it can still be used, i wanted a lower level read for a error check tool
