Special Warning on WD SMR HDD Data Recovery Cases

To all Dolphin DFL users:

Recently we have received many WD SMR hdd data recovery cases by remote support system from Dolphin users worldwide and Dolphin engineers have found many issues and wrong operations from users’ side:

01: Some users get one patient WD SMR HDD and go to extract lost data directly without doing any firmware backup or further diagnosis;
02: Some users backup firmware modules directly without disable 411, this adds to the risk of damaging original module 190;
03: Some users use the same firmware repair concept for old WD drives to repair WD SMR drives without firmware backup;
04: Some users receive failed WD SMR HDD cases from other data recovery companies without any original firmware backup. The user needs to remind the hdd owner to ask for the first copy of firmware modules, specially the original module 190, otherwise, it can be not possible to recover the lost data;
05: Some users extract the files directly instead of imaging the patient unstable HDD. This adds to the risk of further damage to heads or surfaces.

Correct Steps to Recover Lost Data from WD SMR HDDs:

01: Unlock firmware area by writing unlock rom to original pcb or change one sata firmware unlock pcb;
02: Disable 411 and backup 190 and T2data;
03: Backup other important firmware modules;
04: Test firmware modules and find which ones are corrupted;
05: Repair damaged firmware modules;

Western Digital SMR Charger 800067 HDD Spin Up and Down Data Recovery Tips

,

This is one very successful Western Digital SMR Charger hard drive firmware repair and data recovery case. This patient charger hard drive spun up and down repeatedly and seemed like head failure but actually not.

The user tried to swap heads of the patient hard drive but the failure symptoms remained the same.

With the help of Dolphin remote support engineer, the user changed the original heads back to patient hdd.

To recover lost data from this failed charger drive, the user converted the USB interface to SATA by G3 800067 USB to SATA data recovery adapter, backup the original ROM, generate unlock rom by DFL-WD firmware repair tool, disable 411 and write unlock rom.

Next the engineer made a backup of the important firmware modules, specially the module 190, both copy 0 and copy 1. After testing the module 190, the copy 0 190 was corrupted but copy 1 was still good. So the engineer wrote copy 1 190 to copy 0. It was very lucky after the good copy of 190 was written, the engineer enabled 411, power off and on and the patient hdd was repaired successfully.

In many cases, both copies of 190 were corrupted and users need to use DFL-DDP data recovery tool to repair the 190 and finally users need to load the 190 or T2Data to the RAM automatically to fix the all 0000 issue.
