the cdrw software is for the burning process only. If you install it before the drive the drive won't read the software. Thats like saying install your video drivers before the card. boot to safe mode remove the drivers from DM turn off the computer and then remove the drive from the ide cable AND power cable.
BTW you can install a cdrw drive and a hard drive on the same cable with out any problems of recognition of either, you would run into problems with cd to cd burning. just remove the drivers and the drive.
