Usage Instructions

Description

1.) SFDR-I: Uses the USB flash drive storage capacity as per the equipment's identifiable floppy drive
capacity: 1.44M/1.2M/720KB. Capability of being used as the system startup disk. USB flash drive plug-
and-play. Uses the same functions of reading floppy disks from devices standard control system to read
the USB flash drive.
2.) SFDR-II (SFDR-I + File Chooser) Using the file chooser device in conjunction with the SFDR-I will give
the ability to choose any file folder inside the USB flash drive, the maximum size of each file folder is
equal to the original floppy disks storage capacity. The capacity of each file folder cannot exceed the
original storage size of the floppy drive which is identified by the equipment's computer system (1.44MB
/ 1.2MB / 720KB). Files beyond this size cannot be identified by the SFDR. The function of the chooser is
to be able to choose any file folders inside the USB flash drive without limitation on the total file size.
3.) The letter on SFDR type label represents the different floppy drive model. We request that you
inform us on the original floppy drive type when placing an order to avoid mismatching the drive type.
For example:
SFDR-I-I--------------Universal IBM type
SFDR-I-A-------------YD-6639D, TEAC235FG
SFDR-I-B-------------NEC 1137C
SFDR-I-C-------------YD-6037D

3.1 Reading, Writing, and Formatting functions of the SFDR

Reading Function of SFDR:
1.) FAT (FAT16) format is recommended for use with the USB flash drive. If there are any errors when
using the USB flash drive on the SFDR for the first time, it is suggested to format it on a separate
computer system and set file system parameter into FAT (FAT16).
2.) Insert the USB flash drive into the SFDR's USB port. Files inside the USB stick are loaded into the SFDR
automatically when read light of the SFDR is on. Do not remove the USB flash drive during the loading
process.
3.) You may remove the USB flash drive once the read light is off. The SFDR will retain the loaded files
inside its memory even once the drive is removed.
Writing Function of SFDR:
1.) To write any files from the device to the SFDR's memory, you may use the standard copy, remove,
edit, save, delete, etc functions as supported by your device's operating system.
2.) After the data is written to the SFDR, the green light of the SFDR will go off. The read light will also
turn off in the case that the USB flash drive is not inserted into SFDR. Otherwise, the read light will
remain on until the writing process is completed.
3.) The SFDR distinguishes files which have been written into its memory as per the defined memory
capacity of the floppy drive setting on the device. When more files are needed be sure the size of each
file combined isn't bigger than the total memory capacity of floppy drive setting. In the event that the
total size of those files is bigger than the floppy drive's set size, memory space should be released by
deleting existing files.
Note:
1.) When writing files to the USB flash drive, file with the same name will replace the previous one.
