Within DFL-WD hdd firmware repair tool, users get one very helpful firmware repair function: to extract firmware modules from SA region.

To read Western Digital hard drive firmware modules, the firmware repair software usually needs to read module directory(module map) and then read other firmware modules according to module directory. But when the module directory is located on bad sectors or corrupted, the module list is empty and firmware modules couldn’t be read. At this time, users usually find donor rom and loaders of the same microcode to write to patient hdd to access the firmware area or try hot swap method to access firmware modules.

After users have this function to extract firmware modules from SA region, users just need to load loaders to undetected patient hard drives and then read SA region copy 0 or copy 1 and then the software can extract the modules easily and automatically.

For undetected hard drives, only if users get the patient hdd firmware modules, specially key modules, firmware repair will become easier. For example, users can write donor rom and fw to get patient hdds detected and then write patient key firmware modules to access the data area properly.

After firmware repair, users can use DFL-DDP data recovery software to recover lost data.

This is one successful Western Digital hard drive data recovery case study shared by one DFL user in India. The patient drive had head failure, kept busy and had no access to data area at all.

Patient HDD ID:

PCB: 1640 series

To recover lost data from head damaged hard drives, the very first step is to find one donor hdd with donor heads, users usually check the model and pcb number and sometimes, the DCM is to be checked as well.

After finding the donor hdd, users need to open the patient drive in clean room environment and swap the heads.

Next users need to enter the DFL WD hdd firmware repair software and backup the rom and important firmware modules including the 03, loaders, 31, 36, 40, 49, 4A.

Next users can test the firmware modules and find out which modules are damaged and then repair the damaged firmware modules. In most wd traditional hard drives, we need to run the slow fix.

Next we can use DFL-DDP data recovery software to set up disk image project, set up head map, image good heads and then weak heads.

Finally we can extract lost data from the image file or target drive.

This is one successful WD hdd firmware repair and data recovery case study for one DFL user from Bangladesh and all lost data was recovered by DFL-PCIe data recovery hardware tool.

HDD Model ID: WD20NMVW-11W68S0
PCB number: 2060-771801

Failure symptoms:

External hdd was not detected by pc
Data was not accessed

The user converted the USB PCB to SATA PCB(771823) and then connected to DFL PCIe data recovery hardware for diagnosis.

DFL-WD hdd firmware repair tool was firstly used to diagnose the firmware corruption issue and the common slow firmware issue was detected and this issue was fixed by one click.

Next DFL-DDP data recovery equipment was used to set up one disk image project and auto decryption function was used to decrypt the data. Finally all lost partitions and files were recovered.
