Using Intulon DFP7 USB 3.0 Duplicator

Using Intulon DFP7 USB 3.0 Duplicator

The DFP7 USB Duplicator is a 1 master to 7 targets, portable, standalone (no PC required) USB 3.0 duplicator. Because the DFP7 has dedicated function buttons, using the device is very straight-forward if you already know what you are trying to achieve. The only main function without a dedicated button is the secure wipe/erase functionality.

The easiest way to go over using the DFP7 is to describe what each function button does.


This makes an exact copy of the master disk drive to the target drives. The duplicator does not inspect the data or try to make any sense of it. It simply copies the data bit for bit from master to target(s).

That means this function will copy any file system. This function is also the only way to copy encrypted disks or disks with proprietary data formats.

The target drive must be at least the same size as the master drive.


When the file system on the master drive is one of the following:

  • EXT2, EXT3 or EXT4
  • ReiserFS, Reiser4
  • XFS
  • UFS
  • JFS
  • VMFS
  • NTFS
  • FAT12,, FAT16, FAT32, ExFAT
  • F2FS
  • VFAT
  • NILFS2

The duplicator can inspect the file system and determine which areas of the disk contains useful data. It will then go ahead and copy only the areas of the master that contains useful data to the master.

This approach has tow potential advantages:

  1. The copy process will be relatively very fast compared to using CLONE if the master contains little data.
  2. It is possible to clone a master to a smaller disk size if the partition on the master is smaller than the actual master disk size and not bigger than the target.

Since the SMART CLONE function relies on valid master partitions, the master disk must be in a "clean" state prior to using this function. Improperly dismounted file systems might not work. In such a case, the duplicator will display an error message.


The duplicator can format target disks to FAT32, NTFS or EXT4 (linux). After the FORMAT button is pressed, a 10 seconds countdown is displayed on the screen an if no selection is made, the duplicator will default to formatting the targets to FAT32.


This is used to compare a master with other disks. If the master contains recognizable partitions, the partitions are compared with those on the targets. If no partitions are found on the master, then a bit by bit comparison with the targets is made.


There are instance where unscrupulous brands market their flash drives as having a higher capacity than the on-board chip is capable of.

The operating system might even be fooled in reporting such fake capacity. However, if you attempt to fill the drive with data beyond the actual disk capacity, a failure happens.

The duplicator can inspect target drives and determine if they are damaged, fake or genuine.


The ABORT button cancels an ongoing operation. Note that operations cannot be canceled in the initial drive stage before operations start.

The duplicator will work on any storage media with a USB 2 or 3 interface. That includes, but not limited to:

  • flash drives,
  • external USB hard drives or internal hard drives connected via USB to SATA/IDE adapters,
  • SD cards and micro SD cards connected via card readers

Speeds up to 18Gb/min are achievable using the duplicator but your mileage will vary based on the speed of your drive and the USB adapter connecting your drive to the duplicator.

Please see this forum post for information on real-world speeds that were achieved using different disks and adapters.
