One way to achieve the goal is to disable the write-cache
by /CA5. By disabling the buffering to the destination
volume, at least the file I/O can be made sure that the
file-write action is complete before XXCOPY will prompt
for your action (switch the diskette/Zip disc).

However, XXCOPY cannot easily detect when the write-behind
cache for updated directory info is complete that the
operator is not usually sure of when the disk write action
is complete. Besides, the /CA5 will probably slow down the
performance considerably, I'm not sure you really want to
do this.

The best way is to follow the common sense --- wait
until the activity light on the drive is off. If you are
still not sure, just wait for 10 minutes before you touch
the drive (no, I'm exaggerating --- probably a 10 second
wait is more than sufficient).
