You can use DISKPART too, I feel it's a better tool for this type of thing: C:\> ECHO LIST VOL | DISKPART | FIND "NTFS" Volume 1 C System NTFS Partition 20 GB Healthy System Replace NTFS with CDFS to find the CDROM's. You'll have to do some parsing of the results, but this is cleaner and quicker than most methods.
