Take a blank disk that has no scratches on it (circular scratches) and insert it into your drive and make an image. During the imaging process, the disk you should pretty quiet. If you hear a loud "wooshing" sound, especially if it oscillates, then some loose particles are on the head and/or disk. Remove the disk and check for scratches. I recommend frequently clean the head with a cotton swab and 90% alcohol. If you don't see any scratches on the surface of the disk (either side), then you are probably pretty safe.
I don't think there are any "contents" on the AAD disk. These are special analog tracks, and not contain any data that can be retrieved (as far as I know).
You don't use the drive for anything more than spinning the disk and stepping the head. You need to use a dual channel scope to read the analog signal from the head to determine the track alignment.
There is no need to make an image, you can't.
I don't have information on these drives, but Sncboom2K (user here) might.
No, I didn't work on the Copy II ST program, but his office was next to mine. That guy was hysterical! He coded to head banger music cranked up!
