Within the new Seagate hdd firmware repair software, the COM terminal operations are running more smoothly and quickly.
With one simple B command, for example B3, users can get a support list of different baud rates for the current hard drive. Users can select 38400, 115200, 230400, 460800, 921600, 3000000, 6000000, etc to backup ROM or SYS files by COM mode. Please note some old drives don’t support high baud rates.
When the Seagate hard drive is unstable and not detected or busy, when the firmware area is locked(SED lock), the users need to operate with firmware area by COM mode.
DFL Users can download the latest Seagate firmware repair software from the user-only forum: https://forum.dolphindatalab.com/forum-18.html

This is one successful WD hdd firmware repair and data recovery case study for one DFL user from Bangladesh and all lost data was recovered by DFL-PCIe data recovery hardware tool.
HDD Model ID: WD20NMVW-11W68S0
PCB number: 2060-771801
Failure symptoms:
External hdd was not detected by pc
Data was not accessed
The user converted the USB PCB to SATA PCB(771823) and then connected to DFL PCIe data recovery hardware for diagnosis.
DFL-WD hdd firmware repair tool was firstly used to diagnose the firmware corruption issue and the common slow firmware issue was detected and this issue was fixed by one click.
Next DFL-DDP data recovery equipment was used to set up one disk image project and auto decryption function was used to decrypt the data. Finally all lost partitions and files were recovered.
