This patient ST1000LM035-1RK172 HDD is from one DFL user from ivory coast in Africa. The patient HDD has suffered firmware corruption and the HDD ID couldn’t be detected and no data was available.
The user had followed all the standard firmware repair and data recovery steps but the error remained the same. Whenever trying to read the HDD, the HDD reports DWF error and the DWF status register was on and in the COM terminal, the following error messages output there:
Max Wr Retries = 08, Max Rd Retries = 32, Max Iterations = FF, Max Certify Rewrite Retries = 14E8

That means translator regeneration doesn’t help at all and the user tried other firmware repair functions and nothing helpful.
Finally the new function added to DFL Seagate firmware repair tool did the work! The user just used one function Edit ID and write by ABA mode. For LM rosewood series, firmware write can be done by SYS mode(ATA indirect) but when the HDD was not detected, this is not possible.
All the lost data had been imaged with DFL DDP data recovery program finally and the ivory coast was so amazing to see the result.
