That's not so bad. I'm sure it's not everytime,
but when the OS is just looking to see what it
has available. It must be stored in ram somewhere.


I suppose it would be possible to store the start and end block for the
most recently used partition in the screen holes with a check byte,
which would be reasonably efficient, since volume swapping is
infrequent.

Hmm, actually, even if it doesn't do this, it's a reasonable idea, and
a possible improvement over the scheme currently used on the CFFA

Thoughts?

I like it.

The only thing I'd add would be caching the most recent *two*
partitions, so that a partition-to-partition copy was fast.
