How to Image or Recover Unstable USB Flash Drives

,

As for data recovery from USB flash drives, there’re usually several types of data recovery cases including accidental format, deletion, slow recovery, bad sector data recovery, controller corruption repair and recovery, firmware corruption repair and recovery, etc.

We can also devide above cases into two types: chip-on usb flash recovery and chip-off usb flash recovery.

In this article, unstable USB flash drive data recovery(chip-on data recovery) will be focused. This kind of case is easy for all users but users need some professional data recovery hardware tools and adapters.

For unstable USB flash drives, users don’t need to solder chips off, don’t need to read chip data, analyse chip hex, restructure hex data, etc. Chip-off recovery is very difficult for many engineers specially for those who are new to data recovery field.

The following are usually data recovery solutions for USB flash drives:

1, common data recovery software for recovering accidental format, deletion;
2, data recovery hardware tools with features of software reset, hard reset, power reset, ready timeout control, etc, users can consider DFL-URE USB3.0 data recovery hardware(two USB3.0 ports) or DFL-URE Plus data recovery hardware(One USB3.0 port and one NVME port), users can connect the unstable USB flash drives for direct disk imaging or file extraction; If users have other types of data recovery hardware with SATA/IDE ports, such as DFL-SRP or DFL PCIe data recovery hardware or other similar data recovery hardware, users just need to have one Universal SATA-USB Adapter Pro. so that users can connect unstable USB flash drives for disk imaging or file extraction. These tools can actually fix the chip-on recovery cases efficiently;
3, Special chip-off recovery tools are required when the usb flash drives are dead or suffering controller damage or firmware corruption.

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.
