This document discusses the WD USB HDD Image Un-locker Pro-SW6316 tool. It is designed to help data recovery engineers decrypt encrypted images from WD USB hard drives with the SW6316 controller chip. The tool allows users to decrypt images by removing the U14 chip from the original PCB and inserting it into the tool along with the target drive containing the image. This avoids risks associated with soldering skills needed to use the original PCB. The document also provides an overview of data recovery from USB drives and links to other data recovery tools.

WD USB HDD Image Un‐locker Pro‐SW6316 is another WD USB hard drive image unlocker based
on the main controller IC model to help data recovery engineers with a higher success rate of USB
hdd data recovery.
Users just need to uninstall the USB PCB from the USB hard drives and check the main controller
chip ID, if it is SW6316 and then users can use this tool to unlock the USB hdd image. Related

Before users can understand this tool, it’s necessary to learn how to recover data from USB hard
drives. To recover lost data from USB hard drives is mostly more difficult than to do it for SATA and
IDE hard drives. There’re several kind of situations for USB hdd data recovery: 1, If the USB hard
drive is detected in PC, users can use some professional data recovery hardware tools like our DFL‐
WDII to handle on the firmware issue or use our DFL‐DE or DDP to scan the lost partitions and files;
2, If the USB hard drive is not detected in PC, it’s a must to convert the USB interface to SATA
interface or change the USB PCB to SATA PCB and remove the ROM chip‐U12 from the original PCB
to the SATA PCB; 3, After the interface conversion and fixing the firmware problem of the USB hdd,
users need to image the original USB hdd to a good target hdd, however, all data imaged to the

2. good hdd is encrypted which is done automatically by the WD USB hdd hardware design itself; 4,
To view the data in the good hdd, it is necessary to decrypt the image and at this time, we designed
the WD USB HDD Image Un‐locker Pro, users just need to find out the main controller IC model,
select the right unlocker and insert the good target hdd, remove the U14 and insert it to the chip
holder, power on the hdd and connect the USB cable to PC and users can view the data then. Please
note: if the original USB hdd is encrypted by some special software like WD smartware, this one
cannot be fixed by our tool so far. After users are able to connect the USB hard drives and handle
on it and finally able to image the USB hdd to a good target hdd, users may not extract the data as
well due to the encryption and at this time, users need to use the original PCB board including the
main controller ic and U14 chip to decrypt the image. So users need to have very sufficient
soldering skills and very careful and patient data recovery attitude. In this way, users may waste a
lot of time and increase the risk of damaging the chips or even the PCB and finally lose in the
competition. Some common USB hdd with SW6316 controller chip is 2060‐771737‐000
