I'm finding more and more of my old disks have either somehow gotten
dirty, or the oxide itself is coming off. The symptom is:

1. Computer, disk drives, and the usual disks I use with it are
   working fine.

2. Put in an older disk I haven't used in a while. It won't read.
   Examine disk, and it has scratches.

3. If I try to read one of my usual disks, *IT* will now have read
   errors. Examine disk, and *IT* has scratches (i.e. it is ruined)!

4. Take apart disk drive and examine heads. There is a brownish
   crud on the heads. Clean it off with alcohol and Q-tips until
   heads are clean.

5. Computer, disk drives, and the usual disks (except the one ruined)
   again work fine.

I haven't found any way to predict in advance which disks will create
this situation. Before inserting the old disk, it looks perfect from a
visual inspection. Yet after inserting it in a known clean, working
drive, both drive and disk are dirty and disk is bad.
*BE* the change that you wish to see in the world.
