Family: Helios
PCB: 1814

Failure Symptoms:
original rom lost/corrupted
HDD was not detected

The patient HDD-Seagate Rosewood ST2000LM007 has suffered severe LED error in the COM terminal, users cannot enter F3 T> and cannot continue the hdd firmware repair and data recovery.

To fix the LED error, there’s one very helpful rom function-‘Disable Subsystem’.
Function path: DFL Seagate HDD repair tool>ROM Operations>ROM Edit>Disable Subsystem

Before using the function, users need to import the unlock ROMO, After using the function, users can save the new rom and write the new ROM, power off and on, users can easily enter F3 T>

Next users can backup the important firmware modules and start the firmware repair. There’re many one click quick solutions available under the Common Menu.

After the firmware repair, users can use DFL-DDP data recovery software to extract lost data easily.

This is one successful Western Digital hard drive data recovery case study from one DFL user in Peru.

The patient HDD ID:
Model number: WD10SPZX-22Z10T1
PCB number: 800066
Capacity: 1TB

Failure Symptom:
HDD got error state when read modules;
Power Restart constantly

Hdd repair tool and data recovery tools used in this case study:
DFL-WD hdd repair tool
DFL-DDP data recovery equipment

HDD repair and data recovery steps:

01: Lock UA writing, disable 411;
02: Firmware restart and re-enter the software;
03: Backup module 190 by ABA(select valid data of 190);
04: Clear module 190 manually, generate checksum, check module and write;
05: Enable 411;
06: Firmware restart;
07: Enter DFL-DDP data recovery software, repair module 190 auto, got repaired T2data;
08: Load T2data in RAM, and data sectors were recovered.
