Use the screw on the flying lead PCB to fix the flying lead PCB to the hard disk. First, we should first strip the cables to be used and plate them with tin. The shorter the cables, the better, and the longer the cables can be. it is good. Similarly, I want to solder on the “A” area of the flying lead PCB, so that the solder joints in the A “area” and the hard disk board are also tinned, as shown in the figure below.
The better the preparation for the front work, the easier it will be for the back. I personally use two data lines in a group, so that welding is easy, and it is considered a small isolation.
If the welder is not good, you can use tweezers to assist in the vertical welding. This depends on the individual, because this PCB board can be free of welding power and ground, just plug in the USB cable, as shown in the following two pictures:
SED can be understood as two kinds:
1. Firmware encryption ROM or module, such as Seagate 58 triangle board and above, you need to unlock the ROM to read and write the firmware. Others such as Western Digital 1961 and 800041 are in the ID (02 module). Editing the ID has the SED option. This requires the ROM to block SA Or block 02 and edit ID to remove SED, then the hard disk can be recognized normally and DE supports decryption;
2. The main control encryption, such as Western Digital 800067\800069\800041, etc. The main control of this board itself is encrypted, and the unlocking board needs to be replaced to read and write the firmware, and separate data.
In the second half of 2019, some of the new disk boards such as 800067\800069\800041\810035 have their own master encryption, and now they can only read and write firmware and split headers when replacing the unlocking board, because DE can’t decrypt the data area and deal with firmware problems and split headers. After that, you need to change back to the original USB board. At this time, there is no need to decrypt the data for data (the value of the flying line PCB board). Seagate also has new models. The data area is abnormal after unlocking. This type of data can only be written back to the original ROM. Unlocking is also only suitable for handling firmware problems and splitting. AE AF series hard drives, you will find that there are more SED modules.
The main control encryption is nothing more than the manufacturer’s same board written with different firmware, but it cannot be solved, so it has become the main control encryption.
There is a misjudgment, that is, for the new encryption problem
1 Not the original board, so the data still shows encryption
2 Has the customer added a password?
3 190 problem data has become 0. Both the decryption board and the original board output an encrypted state. If you look at some sectors, it should return the same. Then you can judge that the hard disk has become 0.
4 I have encountered it once. It is not the original board that cannot read the data area directly. ABR error is reported directly. This is because I only encountered it once.
