Have you seen this on Windows XPPro SP3 computers:
You have a project to duplicate alot of discs, like over 20 both CDs and DVDs.
After a while, when you finish a copy, you place it on the same Disc Drive and launch Windows Explorer. The CD shows up and the main directory, but you cannot read it or expand.
You try it on another PC and the disc is readable and all the data is there.
Meanwhile on your own PC, you log out and then log back in and sure enough, that CD/DVD you could not read before is now readable.
Is there some Cache limit in the system that is being reached and no longer able to read the discs???
Thanks
