This is one patient HDD firmware repair and data recovery case study from one DFL user in Indonesia.
Patient HDD ID: Seagate ST9500325AS Wyatt 3C
Symptom: Capacity 0 with the following com terminal error messages:

‘Rst 0x08M
RW cmd 0002 req = 89 3E 00 00 17 02 00 00 00 00 00 00 08 8C 08 00 87 97 09 00 08 8C 08 00
opts = 00001121
RW Err = C4090082
RW cmd 0002 req = 89 3E 00 00 01 00 00 00 00 00 00 00 08 8C 08 00 87 97 09 00 08 8C 08 00
opts = 00001121
RW Err = C4090082
RW cmd 0002 req = 75 5F 02 00 17 02 00 00 00 00 00 00 08 8C 08 00 87 97 09 00 08 8C 08 00

To fix the capacity 0 and RW Err, users need to backup rom and firmware modules and sys files and next the engineer got partial sector access issue.

To fix the partial sector access issue for this patient hdd, users need to use the partial sector access auto fix solution, just one click to fix by DFL Seagate hdd repair tool.

Finally the data area was fully accessed by DFL-DDP data recovery equipment.

The common Seagate B2 HDD models are as below:


After connecting the patient B2 HDD to the firmware repair hardware, power on the hdd, users get the repeating LED 0X000000BD COM terminal messages and the patient hdd spin up and down and up and down…

Whenever users get the Seagate B2 patient HDDs, please backup the original ROM, generate unlock rom, write unlock rom, backup important sys files. But if LED has appeared in the COM terminal, users need to backup the original ROM and then generate new ROM for LED repair within the new DFL Seagate hdd repair and then write the new LED repair ROM, next power off and on, the LED issue will be fixed and users can go to DFL-DDP data recovery software and all lost data can be listed for recovery.

If the patient B2 drives have suffered data corruption, users can see hex data but the data is not normally accessed.
