Dolphin team have created new WD smr hdd firmware repair functions to repair and recover lost data from these drives at a higher success rate.

Sector 000000 is one very common problem in the Western Digital SMR hard drive data recovery cases due to the module 190 loading failure to RAM or module 190 corruption.

Within the new DFL hdd repair and data recovery software, users can find very good functions: module 190 repair and module 190 auto loading(T2 auto loading) to RAM and this auto T2 loading is unique and helps to fix many cases other tools cannot fix.

Dolphin engineers will teach users how to backup the module 190 perfectly and this is the most important step to fix WD SMR cases. Next users can use the T2 auto loading tech. to fix cases such as the sector 000000 firmware issue. If T2 cannot be loaded automatically, after power reset, the HDD can be sector 000000 again.

‘Dear Sir or Madam,

I was wondering whether there is a way to still register an account on your Dolphin data recovery forums.
There is an issue with my current just-out-of-warranty-HDD that I would like to try and solve, however there are simply no more tools for me to try out – at least to which I have access to.

Thanks for your time.

Best regards

There’re multiple similar chips on these WD SMR HDDs with PCB number 2060-800077 and 810011. Users are usually confused to find out the correct ROM chip.

WD 2060-800077 HDD Firmware Unlock PCB, click here
WD 2060-810011 HDD Firmware Unlock PCB, click here

When users are trying to use above firmware unlock PCBs, users need to use HDD ROM Chip Pin Reader to read the original rom and write the original rom to the unlock PCB and then install the unlock PCB to original HDD so that the original HDD firmware area can be accessed. If users don’t have HDD ROM chip pin reader, users need to solder the original rom chip off and solder it on to the unlock PCB rom chip location.

Please note: firmware unlock pcbs help only to access the firmware area and don’t bypass the SED V2 data encryption. To fix the SED V2 data encryption issue, users need to use HDD USB-SATA Wiring PCB Pro. or Data Unlock SATA Connectors.
