I have an Acer CDRW 20x10x40 CD writer. It was working fine and I have written a number of CDs on it. However recently I bought CDs from 3 vendors and all of them when I put them in the CDRW and right click for properties showed that they were full (blue in color in properties in windows).
The CDs could not be faulted because I bought them from a different place each time. The writer cannot be faulted because I have used it before. Anyway the problem is before I am beginning to write. Why is windows showing me that the CDs are full (in blue color in properties)? Is my CDRW outdated and there are compatibility issues here or what?

I am using Windows 2000 Prof and Prassi Primo CD Plus. I think previously when I was using Win98SE things were fine. But now even Prassi is showing the same problem and it says disk(ie the CD) is full and it cannot write to the CD and the writing session is aborted. Is this due to the OS Windows 2000?
