We are aware of this problem and are fixing it.  The problem happens
mostly when the root directory, fat, etc. of the first disk are so
short that they can all be cached -- There is code to check media-change
to validate a cached buffer, but it seems it isn't being used as it
should.

The bug has to do with the fact that the directory-structure cache didn't
check for media change, but assumed that its internal tree representation
was still correct.

We apologize for the inconvenience.  The bug is fixed in the upcoming
new ROMs.
