First an admin of sorts note in that reply-list is not an option for
this list on my Thunderbird email. I seem to have to select reply-all
then remember to edit the reply list.

I finally ordered and received a multiport sata card for use on my

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.
Ah, yes, it IS the same connector. But is this in addition to or instead of
the USB power connector?
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?
One option.
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.
The CT has a special connnector that directly powers the eSATA. I have one
in production working that way and another here on my test bench. No
problem powering a 1A 2.5" 1TB notebook drive.
It isn't a eSATA connector, it's a plain vanilla internal SATA
connector with a power supply connector with enough power to drive a
2.5 inch drive.
thank you for the clarification.
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.
It is definitely not wired to power them as the CT is.
You need to power the SATA board and any extra disks separately from
the Cubietruck, or if you must power everything from a single PSU
you'll just need to ensure the PSU has a 5v supply to power the CT
too.
I am going to need a wiring schematic for this :(
I see the wires from the CT are R/B and Y/B. I have power for a
sata/usb adapter that has a separate power supply that taks a 'standard'
HD power connector and converts that to a sata power connector. So the
first question is how many Amps can the CT support for sata. Then how
to do the wiring.
Need to do some ebay searching, probably.
