Ok, I got a problem here I can't seem to figure out. A few days ago, I noticed that my DVD drives were missing with a "code 41" attached to it. I used Microsoft's techinque for fixing it. I backed up my registry and make the edits. Not I have my DVD drives back, but I am notl able to read CD Data disks with them!!!.
I can watch DVD movies, listen to audio CDs, but I cannot read DATA CDs, whether they are burned or pressed. I get an error that tells me the disk is not compatible with windows and it (the disk) needs to be formatted. Looking into it more, I notice that whenever I insert a DATA CD into the drive, my compter thinks it is a RAW file system.

What can I do to get this corrected?

Thanks in advance,
Mako
