Western Digital SMR HDD System Format Data Recovery

It’s possible to recover lost data from Western Digital SMR HDD suffering system accidental format by DFL-WD hdd repair tool and DFL-DDP data recovery hardware tool.

For WD SMR HDD system format, it’s more complicated to get lost data back for data recovery engineers than traditional hdd format.

For system format of WD SMR HDD, except the new system data, all other data area become 0000 if users check the hdd by Hex tool. This is because WD SMR HDD system format will cause data-related firmware module change and in some cases, the data is permanently lost.

For data recovery engineers with DFL data recovery tools, they can fix some of these WD SMR HDD format cases with the following new firmware module solution:


Many DFL users have reported to us that they have fixed many WD SMR HDD cases from their competitors who failed to recover lost data with other data recovery tools.

How to Set The Target Disk Smartly for HDD Disk Imaging

,

To work with Dolphin DFL data recovery tools, it’s very necessary to set one target disk whenever users are trying to read from the original hard drives. DFL-DDP data recovery tool has one unique and very helpful disk imaging feature and that is to record all read operations to the target disk and all read sectors within the data drive will not be read for a second time.

So how to set a target disk smartly?

Users can image to drive: image data drive to target drive connected to DFL data recovery hardware, for example, image from SATA 0 to SATA 1, SATA 2, etc; image data drive to target drive such as external hard drives connected to pc; Image data drive to VHD/VHDX target disk.

Here Dolphin engineers strongly recommend to use VHD/VHDX as target drives. Users can connect one SATA hard drive with big capacity, such as 10TB to pc by the Universal USB to SATA adapter Pro., and then users can create multiple VHD or VHDX drives on this SATA HDD, next users can image different data drive to different VHD or VHDX drives. All these VHD(X) drives are independent from each other.

Why do we use SATA drive and the adapter, because SATA drives are much cheaper than external hard drives and the adapter helps to make the SATA drives portable easily.

How to Unlock WD SMR HDDs Firmware Area without Firmware Unlock PCB

,

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.

WD SMR Palmer Charger HDD All Sectors Zero Recovered Easily by DFL-URE or UREP

,

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.
