You do not show the dmesg so it's impossible to tell what the
kernel thinks the drive is claiming.
If the drive claims to be using 512-byte sectors, everything should
work but potentially be slow due to the drive compensating for
i/o into the middle of 4K sectors.
If the drive is claiming to be using 4K sectors then the partitions
should all have been automatically adjusted to start on 4K boundaries.

Thanks for the quick response Ken.
dmesg indicates the drive reports 512 byte sectors - bah humbug.
disklabel pushed start to sector 64, though.
Looks like I need to go back in and try to manually create the 4k
sectors by careful management of partition boundaries through
disklabel (I was going to DBAN it, anyway).
That was David Gwynne's initial suggestion and I've seen other
comments elsewhere regarding ensuring whole MB boundaries which
appear to suggest you can fool the drive into creating 4k sectors.
Experimentation perhaps...
