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.
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.
