You can't just pull a disk out of a drive with an open file on it, UNLESS
GEMDOS tells you to. To get GEMDOS to tell you to change disks, change your
program to copy files from drive A: to drive B: (yes I know you only have one
drive). When your program tries to access drive B: (ie: to open the file) you
will get an alert box telling you to put in the other disk into drive A:, when
you go back and access drive A: again (ie: to read the second half of the
file) then you will get another alert box telling you to change disks again.

This should fix your problem.
