Bottom posting. I didn't want to spoil the integrity of that post.
Unfortunately some disks were very much adhered. Any attempt to do anything
caused the media to separate. The less adhered ones I managed to free up
enough to read.

As for ethyl alcohol. If you are talking about pure that's a no-go.
Apparently these days it requires a lot of paperwork to even get hold of
it.

The rest I will try though. I went through and ADT'd a lot of my disks.
However the archive is currently missing. So I'll have to redo them from
scratch.

Tristan.
