I tried examining with CTL Alt Del to see what was active, to kill the offending app gripping my CD. None would be active, if I had closed all open apps, so checked the processes running. Tried stopping Direct CD and explorer.exe but explorer.exe won't let me stop it. Has to finish something, which I'm sure relates to the CD, and refuses to end. The grip of death goes on.
I have only had this problem since I had someone switch out my old harddrive and install an fresh one, cleaning and using my old one as an alternate drive. C: has the operating system including Direct CD application, and all applications. E: is just used to store data. I thought perhaps it was because I used the E during a session, then the CD drive, which is D:, but this proved to be a false assumption. I was very careful to ONLY use the E during a session, then reboot by shutting down, then use the CD drive during a session, then reboot, etc, in case some pointer thing was getting confused. The CD lock still happened.
I have large files that I can ONLY save to a CD, and am frantic to resolve this problem. Thanks for any advice you can offer.
