It is now possible for DFL users to unlock the WD SMR HDDs firmware area on the original PCB without special firmware unlock PCBs.

The new solution for WD SMR HDD firmware unlock is available within DFL-WD hdd repair tool and to use this solution, users need to have DFL HDD ROM chip pin reader(Many users have already had this one.) and the steps are as below:

1, Remove the original PCB from data drive;
2, Read the original ROM from original PCB by the HDD rom chip pin reader set without soldering rom chip off;
3, Generate firmware unlock ROM;
4, Write unlock rom to original PCB by the HDD rom chip pin reader set without soldering rom chip off;
5, Install the original PCB to data drive and users can see the firmware area is already unlocked successfully;
6, Users can use DFL-WD hdd repair tool to backup important firmware modules, specially the module 190, smrzone, T2data, etc;
7, Users can image the HDD or extract lost data directly if users have DFL-URE or DFL-UREP by using DFL latest T2 auto loading tech;
8, If the original PCB is physically damagaed but the Main chip and ROM chip are still good, users can use the special firmware unlock PCB and then move the original main chip to the firmware unlock SATA PCB and write original ROM to the firmware unlock PCB for disk imaging or file extraction;
9, In some cases, users need to repair the damaged firmware module 190 or repair the SMR HDD slow issue to continue for data recovery.

The WD SMR HDD firmware repair and data recovery solution is more and more complete and successful and DFL users will be able to fix more and more new data recovery cases.

Please note: the new solution supports 800066, 67, 69, 77, 11, etc but doesn’t support 810033 and 810035 which have quite different rom structure and algorithms. For WD 810033 and 810035, users still need to get the special firmware unlock PCBs for firmware unlock.

This is one patient WD SMR Charger HDD from one DFL user in China who has other data recovery tools but failed to get the lost data back due to the 190 loading issue.

HDD ID:

WD20SDRW-11VUUS0
Family: Charger
4 Heads
Microcode: 6008J
SPT: 1860

This DFL user contacted Dolphin team and bought DFL PCIe data recovery express recharge version and DFL-URE Plus and applied for remote support.

By DFL PCIe data recovery express, the user had safely backup the rom and firmware modules and tested the firmware modules and found the modules 189 and 190 are corrupted with checksum errors. At this time, the engineer had to backup the 190 by ATA but still some sectors failed to be read in module 190. The engineer repaired the module 190 by DFL-WD 190 repair solution and got new 190 and at the same time, the T2 data was extracted as one important part of 190.

By DFL-URE Plus, the engineer could connect the Charger USB HDD directly, before loading T2Data, all sectors were found as 0, next the engineer selected the menu ‘Edit Head Map in RAM and Load T2’ and the engineer loaded the T2 data automatically.

After T2 auto loading after power reset, the engineer went to check data area again and the hex data becomes normal.

Next the engineer went to file extraction and the lost partition, folders and files were perfectly listed and finally all lost data was recovered.

Slow problem is very common firmware failure in western Digital hard drives, it is also the same situation for WD SMR hard drives. But please note: Slow issue can also be caused by physical weak head or weak platter surface. It’s not possible before to fix the SMR HDD slow issue by the traditional ‘slow fix’ solution.

Within the latest DFL all in one data recovery tool V2.3, users can easily fix the slow issue without affecting the data and the solution has helped many DFL users to get lost data back from the WD SMR HDDs.

The WD SMR HDD slow fix solution is available within DFL-DDP data recovery software.

All users need to do is to activate TLER, click to modify module 01 and 02 and input the read and write response time.

But if the slow issue is caused by weak heads or downgraded surfaces, users need to backup the SMRzone and module 190/T2 for running selective head image.

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;
5, This step is available in Dolphin user-only forum;
6, Power off and on and the patient HDD was detected perfectly;
7, Enter DFL-DDP data recovery tool, all lost data was recovered successfully.

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.
