This is one PCB damaged and firmware corrupted WD5000BMVW-11AMCS4 patient hard drive and its PCB number is 771820.
This patient PCB is for one DFL user from Italy. When the user got this patient HDD, the original PCB was damaged, the ROM chip was burnt and the HDD didn’t spin up at all.
To fix this patient hdd and get the lost data back, users need to have DFL-WD hdd repair tool and DFL DDP data recovery tool and the data recovery steps are as below:
1, For these non-spinning drives, the very first step is to get the patient drives spinning again by getting one donor PCB with the same PCB number;
2, Enter DFL-WD hdd repair tool, get the module list and check the microcode from module 11 or other overlay modules;
3, This step is available in Dolphin user-only forum;
4, Enter DFL-WD hdd repair tool again(if users cannot enter program successfully, users can try to short connect tv9 and tv10), test all firmware modules and found out module 02 was corrupted, the HDD was still not detected;

This DaHua DVR data recovery case study was for one DFL user from India. This is one formatted Dahua DVR hdd and the Indian user has used other CCTV DVR data recovery tools to scan the patient DVR hdd but get nothing or get videos with only 2MB, they are just some small video fragmented files.
When the user received this DVR patient HDD, the DVR brand is unknown. No one told the users about the DVR brand and then the user contacted Dolphin team for remote technique support.
Dolphin engineer checked the hex data of the DVR patient HDD and analyzed the data carefully and found out the dvr brand is DaHua DVR.
The patient DVR hdd was formatted and the file system info was overwritten and for this kind of DaHua DVR video recovery cases, users need to select ‘Deep Analysis’ within the Dolphin DVR recovery software and start the video fragments analysis, collection and restruction and finally all lost videos will be listed properly.
With the help of Dolphin engineers, the Indian client had got all his lost videos back.
