Here is the video on how to recover lost data from WD10JMVW 11S5XS1 undetected hard drives without data access.
Patient HDD ID details:
Model number: WD10JMVW 11S5XS1
Family: Firebird
PCB: 2060-771823-000
Head number: 4
If users enter DFL-WD hdd firmware repair program, the HDD ID couldn’t be detected properly and the firmware modules are not accessed too.
To recover lost data from this kind of cases, users need to short connect TV9 and TV10 and enter program, backup ROM, disable 02, firmware restart, re-enter the program.
After above steps, the firmware modules were already available.
Next the engineer went to click the common repair-Slow fix and unlock smartware.
Next the engineer tested all the firmware modules and found out which modules were corrupted. The module 32 was corrupted, the engineer found one donor 32, wrote to hdd and cleared the module 32.
Next the engineer enabled module 02, firmware restart.
Next the patient HDD was perfectly fixed and the data area was accessed too.
Next the engineer opened DFL-DDP data recovery program and all lost data was perfectly recovered.

Within DFL Seagate HDD firmware Repair Tool, users can go to COM terminal. After writing unlock ROM, power off and on, users can find the handshake value, send unlock key and keep pressing ctrl+z at the same time. Users must enter F3 T> before the patient drive entered LED status.
After entering F3 T>, things become easy.
Users can easily backup the important SYS files, clear g, clear smart, write down nglist entries, regenerate translator, clear media cache.
After the firmware corruption is fixed, the user opened DFL-DDP data recovery program and all lost data was perfectly recovered.
