I have the 256MB flash drive. The documentation seems to imply that the same drivers will work with any Maz drives. The archive also contains an "manager" which allows you to assign password access to the drive as well as making the device itself bootable.
The instructions indicated that you only need these drivers when running with the Win9x kernel (I presume with NT as well), but that Win2K and better have a universal driver that handles USB mass storage devices.
The manufacturer may also be listed as MAZ Pc Supplies.
Hope this helps you. I caught hell trying to find theese drivers on the Net.
