When you wrote only one item in sd.conf you must write a ; and not ,<br>
at last letter.<br>
But this HDD you must not list in sd.conf it will present ashift=12.<br>

but I just can't get my HGST 4K disks to get the 4TB capacity in the zpool.<br>
I've cross referenced and verified multiple times and this should work<br>

"ATA HGST HDS724040AL", "physical-block-size:4096",<br>
