] Only when you write with BOTH computers at EXACTLY the same time.
Approximately at the same time is good enough to get into deep troubles. And 
on the MSX turbo R, approximately is not even necesary because of the sector 
buffers of DOS2. They keep copies of the most recently used fat and directy 
sectors to reduce the amount of head movements necesary. Ideal scenario to 
get concurrency problems when both systems have write access to the same 
partition.

Just try the next thing on your MSX turbo R:
1) Start DOS2/command2.31
2) Set the amount of sector buffers as high as possible, for example 
BUFFERS=18
3) Go to one of your harddrive partitions
4) Enter a directory
5) Enter the dir command
6) Turn of your harddisk and pray that your computer does not crash because 
of the possible powerpeaks
7) Enter the dir command again, and voila, you will see the contents of the 
directory again...
