They do work.  You might run into problems due to a missing slice
table, so it's not too easy to label them (but it's possible).

You might get unit attention warnings after a media change.  Ignore
them.

You won't be able to use media with a sector size of 1024 bytes.  The
current sd driver does only support 512 bytes.

You should setup your drive to report ``direct access'' (w/ removalbe
medium), not ``optical''.

(And yes, i've once tested a Maxoptics drive.)

Never trust an operating system you don't have sources for. ;-)
