Driver for interacting with CDROM

NTDEV
1

Hi All,

Apologies for sounding repetitive.

Kindly help me with key concepts I need for writing a very basic driver
which when invoked should get a file from cdrom

Im able to install my driver as E: and also allocate memory to it.

Now my user application points to E:\ and requests for a file E:\ABCD.txt

myDriver should now go to cdrom [D:] and fetch D:\ABCD.txt, and return it
back to user application. i.e. the read-write which will happen in myDriver
should be same/similar to how an actual cd-rom reads-writes just that I’m
providing a hop in between.

Kindly help me with how to perform this read write.

Simran,

Which driver have you written? Is this a miniport driver? if so you dont
need to bother about fetching abcd.txt. cdfs driver will do it for you. all
u need to support is reading blocks that come to you as parameters in srbs.

Thanks and Regards,
