Are you doing direct drap and drop. If so the Driver that allows you to this should have an Icon on the Tray of the Task bar. If there is one there right click on it and there should be and option to scandisk the CD disk. This sometimes corrects these problems but most like that disk you are using has worn out.

Yeah, did you format it first, or just copying stuff to it?  If just copying, it is probably acting like a CDR, not a CDRW.

This means you finalized the disk, you should either write multi-session or something like Mount-Reyneer (hope that's the right way to write it)

depending on the way you look at  the volume data, it may consider that the disk is readable only, thus tell you the volume is full.  instead highlight the files on the volume, click right mouse, and properties, that will tell you the real amount stored on the disk.

you can use other recorder-software, as Nero or director CD. initialization your CD-RW medium by UDF format,  get across this way, you can recording data of incremental. when you finalized the medium, that can be read data from CD-ROM driver,but the medium is UDF filesystem. Did this answer your question?

I often find that when I eject a CD or DVD, I am not able to add more data to the disk, and the properities return "zero free space".  This is after using less that 1% of the disk's storage capacity.  This can get expensive after a while.  What am I doing wrong which results in changing the status to "zero free space?"

Can I change a "zero free space" disk to a disk which once again I can add files?
