(stuff about C LTD vs. Supra controllers, etc.)

I've been following the discussion about these various controllers and hard
drives, and the inability of certain controllers to handle 256-byte sectors.
What nobody has said is whether it's just 256-byte sectors that are the
problem, or whether the controllers ONLY handle 512-byte sectors.  Why do I
ask?  Well, I have access to a brand-new Sony SMO-D501 magneto-optical drive,
with the removable 650 megabyte platter (well, it's a flippable 325 Mbytes
per side, if you wanna get picky), and the blank platters that were shipped
with it are 1024 bytes per sector.  The unit has an ESDI interface, but also
was shipped with a SCSI controller, and I'm trying to figure out if the unit
will work with an Amiga (just for testing purposes, tho; I don't have the
$3400 bux or so to buy one for myself, but it would be interesting to play
with, until it's needed for the project at work that I bought it for).

So, my question is, are any sector sizes other than 512 (i.e., 1024) bytes
supported by the popular A1000 controllers (I currently have a Supra 4x4, but
I am toying with upgrading to the C LTD Kronos unit, when it becomes
available "RSN")?
