This is a very common problem with decommissioned enterprise SAS drives and also typically very easy to fix.
All you need is a "true" HBA in the server that is reformatting the disks
Dell PERC cards and HP Smart Array controllers cannot communicate with 520-byte sector disks whatsoever, even when put into "HBA mode".
The cards inside the [[Servers|Kurisu and Okabe]] servers have been flashed with the "IT mode" firmware, as their PERC cards were old enough to be flashed using [https://fohdeesha.com/docs/perc.html a script]).▼

The sector size of a disk can be reformatted to 512 bytes using <code>sg3utils</code> with the command below:
<code>sg_format -v --format --size=512 --six /dev/sgX</code>
Of note,
* Netapp needs ten-byte

He has uploaded a video of the process to YouTube [https://www.youtube.com/watch?v=mAhS_sk3wKE]
So the hardware route is a dead-end :(
