The user couldn’t enter F3 T> at all.

The user was then suggested to swap heads to continue the hdd repair. After head swap, the patient drive was detected and the data area was accessible. The user set up one disk image project, set up head map and finally imaged all heads by DFL-DDP data recovery software.

Here is the video introduction to above case.

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.

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.
