- I don't think you need to worry about this. Usually a Minix formatted
- filesystem will have a valid TOS boot block, with the FAT configured to
- indicate 0 sectors free, thus preventing you from writing anything to it.

- The programs need to have been written correctly in the first place, i.e.,
- allow for file names longer than 13 characters. If you have a program that only
- allocates 14 bytes for filenames (as most TOS programs do) and the directory
- routines return a filename much longer than this, you're bound to corrupt
- your memory. Depending on whether the program stored the name in a local or
- a global/static variable, you could trash the program's stack or other data
- areas. If the stack is trashed, the sort of lockup you observed is not unusual.

- The minixfs.doc file says the partition type must be GEM, therefore, you
- cannot make the partition hidden to TOS.
