The Floppy Disk may be bad. See if the Floppy Disk can be read
by a Personal Computer. Does the green light on the floppy
drive come on when you access the disk? If so, power is
getting to the floppy drive. If not check connections of floppy
drive inside the computer module. See Computer/Pendant

Computer Module is communicating with the Flash Drive you
will see "Detecting IDE Primary Master…Scan Disk SDCFB-256".
If the Mother Board of the Computer Module is not
communicating with the Flash Drive you will see "Detecting IDE
Primary Master … None".
