I finally ordered and received a multiport sata card for use on my cubietruck: http://www.ebay.com/itm/SATA-2-0-Port-Multiplier-Card-1-To-5-Port-SATA-Card-SATAII-Riser-card-/151747062952?hash=item2354d46ca8 From past emails I learned this is supported, but now how to wire up a couple 2.5" (notebook) sata drives. The questions are: What is that white connector for?
It's a power connector. You need to attach a floppy type power input to it.
How can I power ths card so when the CT is off it is off?
By powering both using a separate modified AT/ATX style PSU?
And most importantly, how do I power the drives? The CT comes with a single sata cable taking power for the drive from the board. Now I to learn how to wire this all differently.
Are you sure it provides power on eSATA? The vast majority of devices that provide eSATA capability don't supply +5V over eSATA (+12V is not in eSATA spec at all) and require a separate +5V to be supplied via, e.g. USB. Either way, the port multiplier won't take power from eSATA, so you will need a separate PSU to provide power for the PMP and the disks at the very least.
