Is it possible to find out what type of media is currently in a CD or
DVD rom drive. For example R or RW and how much space?
To be used to check if there is space and ability to write to the
current drive with data.

I think the best you might do involves checking the contents
drive for a disk and inspecting the contents and/or the file
system of the drive...

ie, reading information about the "file system" tells you if it's
a DVD or CD or other media. I believe the same things that
happened with floppy drives, happened with DVD's as well.
For instance, the floppy disks started out with a particular
file system formatting (single-sided, then later came double-
sided, then later double-density... and so on). Keep that in
mind when dealing with this topic. CD's carry different
file systems as well, because there are at least two formats
that I know of, a 650K CD and 700K CD.

Scroll down to Drive Info on this page...

Check media type...

You can check the file-system used on the disk...

You can check the amount of free space...
