I have a AD-7200A which is installed in an external enclosure. The drive isn't used very often.
Now I wanted to try a DVD-RAM on this unit and encountered several problems:
The disc isn't always detected, sometimes it takes a very long time while the drive tries to detect the disc. If recognized, there are write errors, reported.
With DVD, the drive also has hard time to recognize the media.
I already opened the drive and cleaned the lens with Isopropanol. No improvement.
I can also rule out system related problems since other drives work fine, and the problems show up on my laptop (where I connected the drive to for troubleshooting), too.
CD recognition seems to be okay at the moment.
Any ideas? Must I prepare myself to bury the drive?
