Currently, WD portable hard disks are with interface of USB2.0 or USB3.0. And a USB cable is needed if we want to get stored data. One side of the cable is connected to portable disk, while the other side is connected to computer’s USB port. In MRT software, there is one special utility called WDC Marvell USB. The basic requirement when using this utility is that WD portable disk can be detected by operating system. Which is to say, when the disk is connected to computer, it should be found in “Device Manager”, or we can not use WDC Marvell USB utility when it is undetectable in operating system. As shown in pics:

WD portable USB drive is directly connected to host computer via USB cable, so that we can not execute operations like power off/on, soft reset, hard reset and skipping when native USB interface is used. So when facing with bad tracks or bad sectors, the disk will keep long time busy or even get stuck, which will largely affect the speed and quality of the image. The example we have mentioned just now is the situation that the disk can be detected normally by computer, for those which can not even be normally detected by operating system, does it mean no any chance at all? Absolutely, the answer is no.

When the above situations occur, we can try to convert USB interface into SATA interface, so that we can try to connect the disk to MRT hardware card. For disk with bad sectors, we can set error handling parameters in DE utility; for undetectable disk, we can try to fix it under firmware level first, then do the image.

Part One: How to convert USB interface into SATA interface

The first method is to replace PCB board directly:

If we want to replace USB PCB board directly, we need to find the corresponding SATA board first, here is the pic of comparison table of WD 2.5′ portable USB PCB number to its corresponding SATA PCB board number:

After getting corresponding SATA PCB board with same MPU chip, we need to remove the ROM chip from USB PCB board and then weld it to SATA board; or we can use programmer to read out the ROM data and save it, and use software to write the saved ROM data to the chip of SATA board. We need to screw up the SATA board in the end.

The second method does not need to change PCB board, but we have to solder wires:

Before soldering wires, we need to locate four points on the USB PCB board, they are E71, E72, E73
and E75. The pins of these four points belong to data interface pins, as shown in the pics:

Then, we need to remove the USB PCB board, and remove the capacitors of those four points from the PCB board with a heat air gun. The location of these four capacitors are shown as follows:

One more SATA data interface is needed. We can see a SATA data interface has seven pins, three longest pins are ground electrodes, and the remaining four pins are data interface pins, of which pin 2 corresponds to E71 point, pin 3 corresponds to E72 point, pin 5 corresponds to E73 point, and pin 6 corresponds to E75 point. As shown in the picture:

Finally, we need to use wires to weld those corresponding pins and points together, and till that time, all operations are done, and the data can be transferred normally.

2. In “Data Explorer” utility, if we choose “Task params ->Command to Read -> Read from active MRT Utility ->USB data decryption”, then the data is decrypted when users do the image or open file system.
