bit amazing how fast its going for you - while it took whole day for me to do a single disk.

We can exclude the logical block guard / reference tags. Security is turned off.

// i'll think about it; there are some other options available in sg_format and seachest tools. If i recall there was something you could do from seacheast tools, and lastly there is firmware flash. If you feel like adventure you could try testdisk.
That is because I've already run that command. I've also tried other variations, formatting to 512/advanced doesn't seems to be possible. These Seagate drives have been somewhat painful, most people with this issue has HGST drives, and I have no problems with those.

maybe just try flash hgst drive to generic firmware?
The drive in question is Seagate, but anyway it worth trying, at least EMC firmware on previous Seagate generations was not locked for cross-flashing to a generic one.

Try it 1:1 a second time after failure and double-check that you replug the drive after every single attempt, drive needs power off and on, soft reset is mostly not enough.

Also check with sg_write_buffer:
Code:
sg_write_buffer -vvvvv -I file.lod -m 5 /dev/sgX
#be vvvverbose, blow out payload in full size on mode5, check that you use the s'g' device, replug and check

sg_write_buffer -vvvvv -b 4k -I file.lod -m 5 /dev/sgX
#be vvvverbose, blow out payload in 4k-chunks on mode5, replug....
Also try mode7 and mode4 with and without chunks and replug between every attempt.
If all this doesn't work, then the firmware on the drive has locks. Pls post the logs, maybe this helps further.

Edit:
Seems that the more recent locks with IBM-fw are bad:
