I just picked up a bag full of 5.25" disks, that are completely
soaked by rain. How do I dry them so that
a)they are usable at least long enough to transfer the software
b)I run a reasonable chance of saving the labels

Greetings Max,
Any chance of using a Bell jar at a local school to create a vaccum to
draw out all the moisture?
If so do it very slowly....

Normally you need to "freeze dry" something like this. That means
slightly heating it (heat lamp through a window into the Bell jar or
vacuum chamber) and having a "cold trap", which is a cold surface
to freeze off all the moisture. You don't wantt to run all the moisture
through the mechanical pump. It takes a good, two-stage mechanical
pump to do it. You probably need to get down to about 200 microns
to freeze it all off. When you suddenly get lower pressures, you know
you're done.

I acquired a load of C64 disks some time back that were all completely
soaked. I just let them sit for a couple weeks in my basement and they
worked just fine.
