How to Recover WD10JMVW-11AJGS2 Encrypted Hard Drives

,

WD10JMVW-11AJGS2 is one Western Digital SED laptop hard drive. It’s very common to deal with the firmware corrupted cases of these WD SED HDDs.

For this patient WD SED HDD, the firmware area couldn’t be accessed directly, the rom couldn’t be read either. The patient HDD was detected wrongly and running slowly.

To fix the firmware issue, the engineer short connected tv9 and tv10, read rom, disable 02, slow fix, firmware restart and the patient hdd was detected properly by DFL-WD hdd repair tool.

After the firmware repair, the user opened the DFL-DDP data recovery software but the result was bad because no partitions were detected, no folders, no files.

The user viewed the source drive sector 0 and didn’t find any partition mark of 55 AA and other hex data was not normal at encrypted status. The user tried using the auto decryption function but the software asked for inputing the software and finally failed.

The user went back to DFL-WD firmware repair software, went to FW Operations>Module Editing>Edit HDD ID>Security Subsystem, ticked the SED and firmware restart, went to DFL-DDP, the lost partition, folders and files were all available for immediate data recovery.

New Method to Read and Write ROM for Seagate and WD HDDs

,

Users have different options to read and write ROM from Seagate and Western Digital hard drives.

For many hdds, users can use firmware repair tools to read and write ROM directly.

For some new hdds, firmware repair tools don’t support to read or write ROM due to SED lock, MCU lock or other PCB issue or ROM chip issue. At this situation, users can only use flash programmer to read and write rom from the ROM chips.

For traditional flash programmers, users need to solder the ROM chips off and put the ROM chip to the chip holder to read and write rom.

Not all engineers have good soldering skills and Dolphin team offered Chip-on HDD Flash Programmer Smart, users just need to remove the PCB and then users can use the pin reader to read and write rom without soldering the rom chips off.

Now users don’t need to remove PCB, don’t need to solder the ROM chips off, users just need to install the HDD ROM programming clip adapter to the HDD and then users can use Chip-on HDD Flash Programmer Smart and its software to read and write ROM easily.

Users can read details of HDD ROM programming clip adapters here.
