DiskDupe automatically adds your A: and B: drives to the but other drives need to be specified in the Setup|Drive menu. DiskDupe
supports all floppy drive types, although some drives need special
controllers to operate.
Notes:
Simultaneous Double Sided (SDS) drives read to and write from both drive
heads at the same time as opposed to regular drives which can only operate
one head at a time. This can increase throughput by up to 50%.
The 2X notation denotes a Double Speed drive, a special drive that spins
twice as fast as a normal drive and copies disks twice as fast. 2XSDS
denotes a Double Speed SDS drive. Some double speed (600RPM) 1.44MB drives
can also be jumpered to run at 720 RPM. 1.44MB 720 RPM drives are only
supported with the Allegro II.
The 4X notation denotes a 1200 RPM 1.44MB drive. DiskDupe supports these
drives using the Allegro II controller with a 486 or better CPU.
Some older Sony double speed drives can copy 720k disks at double speed and
1.4Mb disks at regular speed. When using this kind of drive, you must set it
up in DiskDupe as two separate drives. For 720k disks on such drives, set
your drive as a 3«" 720k 2X and for 1.4Mb disks use 3«" 1.4Mb.
