If the Creative Micro N200 is formated FAT32, and you don't need
Extended Attributes on your FAT32 devices, look for the "/EAS" switch on
the FAT32.IFS line in the CONFIG.SYS. This is what enables Extended
Attributes and creates the EA DATA. SF, WP ROOT. SF files on you FAT32
volumes.

If the Creative Micro N200 is formated FAT16, I am not sure of a way to
disable the EA's.

Thanks for all the work you did in figuring out the Creative Micro N200.
