Extract .LOD file (Seagate) from .FWH file (Dell)

Thanks on that SWM!
So far it has reacted after --fwdownload command with missing sense data errors but after restarting it has shown up without safe mode enabled with the same signature as it was in the safe mode before flashing:

Now I am issuing secure erase command, it has not rejected as before but there is no confirmation either so I am waiting that half hour.
Should I rename it in origin name.bin next time?

Posting again because there is no my earlier post.
I got error sense data, but after restarting it shows up as a devide without safe mode with the sme signature as before:

Also after flashing it has not rejected secure erase command, but ether confirmed.

Hi guys,

I have a batch of Seagate ST33000650SS 3TB SAS drives running stock factory firmware (0005). I want to cross-flash them to the Dell RS17 firmware specifically to gain control and disable the Background Media Scan (BMS), which is causing issues on my setup.

I tried the common method of stripping the first 208 bytes from the Dell package to isolate the raw microcode, but the drive rejects the flash payload. It's clear that removing the Dell container header breaks the file's internal 32-bit checksum and misaligns the Seagate signature blocks.

Since the hardware family is identical, what is the current tool, Python script, or method used to correctly recalculate the Seagate firmware checksum and adjust the header signature after removing the OEM capsule bytes? I am trying to avoid using a hardware flasher if this can be achieved via SAS pass-through commands.

Any direction on how to fix the modified .lod/.bin checksum would be highly appreciated.

Thanks!
