The JMS567 is a USB to SATA bridge with one SATA port. So there must be 
some RAID capable port multiplier like JMB393/394 behind the USB bridge.

A similar problem was reported 2010 for a device with JMB393. See this 
thread on our old mailing list:

Which proves that there is some vendor specific ATA pass-through 
functionality available. Unfortunately, JMicron did not reply to my 
request for information, see:

If possible, please test the JMraidcon tool mentioned in ticket #705. 
Don't do this on a production machine, as the tool uses actual ATA WRITE 
commands to a specific sector.
