>>I routinely back up to RW CD's. All of the usual error traping is in place. However, Is there a way to find out if the cd in the drive is, in fact, RW and not R ? I use "direct CD" and the CD drive appears as a normal drive ie E: Any Ideas ? Thanks in advance.

Stumbled on the answer. If diskspace()for given drive=-1 and drivetype()=5, it is not RW, therefore must be R. I also tried to setvolumelabel() with "Focus" library and returned "F", that works too.

Thanks for everyone's input
