Peripherals - Pocket Service Guide 3.5" MICRO FLOPPY DISK DRIVES 3.5" MICRO FLOPPY DISK DRIVE There are three types of micro floppy disk: • Double-Sided Double-Density (DSDD), formatted at 720 KB and used on 720 KB, 1.44 MB and 2.88 MB drives. • High-Density (HD), formatted at 1.44 MB and used on 1.44 MB and 2.88 MB drives. • Extra-Density (ED), formatted at 2.88 MB and used on 2.88 MB drives. Bear the following rules in mind when using these disks. • The 2.88 MB drive can read and write to 720 KB and 1.44 MB disks; the 1.44 MB drive is compatible with 720 KB disks. • Only MS-DOS release 5.0 can recognize 2.88 MB drives. The earlier DOS releases will recognize the 2.88 MB drive as a 1.44 MB drive. • The 1.44 MB drive can format 720 MB disks by using the following formatting command: Format/n:9/t:80, or /f:720 . • The 2.88 MB drive that uses MS-DOS 5.0 can format 720 KB and 1.44 MB disks with the simple Format command. CONFIGURING DRIVE JUMPERS Jumper settings on the floppy disk drives must not be changed from the default configuration shown in the figures of the drives. The only exception is the TM jumper (terminator), which must be removed when the 5.25" drive is installed as the system’s second drive. However, this terminator must be present if the 5.25" drive is the only one present in the system. The terminator is always present on 3.5" drives, and is soldered on the board. The cross-over of some of the wires in the floppy disk’s signals cable determines the drive’s physical address. The drive attached to the first connector is recognized as drive A, while the drive attached to the second connector is recognized as drive B. Therefore there is no need to make any jumper settings on the drive to determine its address. As a general rule, all floppy disk drives must have the second jumper DS installed (in the ON position); in some drives, this jumper is identified as DS1 since the jumpers are numbered DS0, DS1, DS2 and DS3. In other drives, however, this jumper is identified as DS2 as the numbering of the jumpers differs, such DS1, DS2, DS3 and DS4. 3.5" MICRO FLOPPY DISK DRIVES 4-1 4 Peripherals - Pocket Service Guide 1.44 MB FDU JUMPER 4-2 PANASONIC JU-257-03T PANASONIC JU-257-03P DESCRIPTION SA450 SETTING D0 Drive selected as DRIVE 0 OFF D1 Drive selected as DRIVE 1 ON D2 Drive selected as DRIVE 2 OFF D3 Drive selected as DRIVE 3 OFF MO Spindle motor controlled by the Motor On signal ON MS Spindle motor controlled by the Drive Select signal OFF DC Disk Change is the signal on pin 34 of the interface connector ON RY Ready is the signal on pin 34 of the interface connector OFF TM Terminator ON 3.5" MICRO FLOPPY DISK DRIVES Peripherals -
