Since it's translating the "passthrough" drive into a SCSI device, it's 
probably just not handling that property.  Don't forget, that ARC-1220 
is an 8-yr old card, from back before "advanced format" drives were even 
a thing to be an issue.  Just use the gnop trick to force the pools to 
4K alignment during creation.
