Seagate HDD SATA Reset but Long to Be Ready

,

This is one very common Seagate F3 hard drive firmware repair and data recovery case study.

Patient HDD Symptom:

In the com terminal, the drive outputs SATA reset and it shows the drive doesn’t have major firmware corruption but the problem is that the patient hdd doesn’t get ready and users need to wait for a long time to be ready.

For this kind of case, users need to be very patient with the patient hdd, users need to enter the main firmware repair software interface, sometimes, users need to manually select hdd family or need to use boot mode to read hard drive ID from the PCB.

After the patient hdd gets ready, users can unlock the firmware area and backup important SYS files or backup important sys files directly.

Next users just need to disable vacant active and turn off the media cache and then power off and on the patient HDD, the patient HDD will be perfectly fixed. If this kind of simple repair can fix the patient HDD failure, users don’t need to regenerate translator.

How to Recover WD10JMVW-11AJGS2 Encrypted Hard Drives

,

WD10JMVW-11AJGS2 is one Western Digital SED laptop hard drive. It’s very common to deal with the firmware corrupted cases of these WD SED HDDs.

For this patient WD SED HDD, the firmware area couldn’t be accessed directly, the rom couldn’t be read either. The patient HDD was detected wrongly and running slowly.

To fix the firmware issue, the engineer short connected tv9 and tv10, read rom, disable 02, slow fix, firmware restart and the patient hdd was detected properly by DFL-WD hdd repair tool.

After the firmware repair, the user opened the DFL-DDP data recovery software but the result was bad because no partitions were detected, no folders, no files.

The user viewed the source drive sector 0 and didn’t find any partition mark of 55 AA and other hex data was not normal at encrypted status. The user tried using the auto decryption function but the software asked for inputing the software and finally failed.

The user went back to DFL-WD firmware repair software, went to FW Operations>Module Editing>Edit HDD ID>Security Subsystem, ticked the SED and firmware restart, went to DFL-DDP, the lost partition, folders and files were all available for immediate data recovery.

How to Repair and Recover Seagate SED HDDs

,

There’re more and more SED hard drives used in the pc market and when these SED protected hard drives are damaged, users need to diagnose the failure causes, unlock the firmware area, backup firmware modules and then recover lost data.

To repair Seagate SED hard drives, users need to unlock the firmware area first. To unlock the firmware area, users need to backup rom and generate unlock rom. To generate unlock rom, users get three options:

01:  MODE 1
02: MODE 2 (AF, 91, CF)
03: MODE 3 (AF)

MODE 1 is for standard Seagate F3 SED hard drives, Mode 2 is for new generation of AF, 91 and CF families, MODE 3 is for old generation of AF family.

After generating and writing the correct unlock ROM, the DFL Seagate firmware repair software sends unlock key and unlocks the firmware area successfully.

Dolphin DVR FAQ-DVR Module Works While other Modules not

,

More and more data recovery engineers are using Dolphin DVR data recovery software to recover their lost valuable videos.

For some new users, they may meet one issue: when users are trying to open the CCTV/DVR data recovery module, digital camera recovery module, video recorder recovery module and video repair module, only CCTV DVR recovery module works but other modules keep silent and doesn’t respond. This issue is caused by the lack of software running environment below:

X64-VS2015-running-environment.zip
X64-VS2017-running-environment.zip

Users just need to download above files and install them on computers and then Dolphin DVR users can use all software modules successfully.
