Esata - Sata query

I have a couple pcs here have a dedicated Esata port on motherboard. I
also have a number of Sata hard disks just sitting unsued on a shelf.

I'm wondering if it's ok to run a standard usb cable from the Esata
connector out the back of a pc and connect it to a regular Sata drive.
I'd of course give it it's own power supply using a "special" cable I
already have.

Aren't the SATA/eSATA cables completely different than the USB cables? The
ones I have most certainly are, just looking at the connectors.

ESATA is the ******* child of standards.

People have been screwing around with it to such
a point, I couldn't tell you what additional interfaces
they've added to the connector.

You see, they *do* put USB pins on at least one flavor.
Just for the confusion it will cause.

"EUHP pinout"

USB ESATA EARS-for-power

P1 +5V P5 GND P12 VBUS (may be +12V or +5V!)
P2 D- P6 TX+ P13 GND
P3 D+ P7 TX-
P4 GND P8 GND
P9 RX+
P10 RX-
P11 GND

original
pins as
subset

There might be *at least* four or five connector
types for these. Plus, you'll need your voltmeter
to check what is on P12 and whether it's the
right thing for your adapter. (I wouldn't use it
without checking first what is on P12.)

Look in the barrel with a strong light, to
start your journey of discovery.

While the Wikipedia article on ESATA is better than
nothing, I don't think it has seriously addressed
all the variants. I kept seeing little blurbs where
small companies seemed to be messing around, and the
SATAIO page made no mention of the options at all.

P5-P11 Original pinout
P5-P11 + P12-P13 Ears +5V for 2.5 drives
P5-P11 + P12-P13 Ears +12V for 3.5 drives
P5-P11 + P12-P13 Ears + USB2 etc
P5-P11 + P12-P13 Ears + USB2 etc

You won't catch me using one of those ports!
Not interested.

If you use a seven pin ESATA to SATA cable (if you
can find one), then that solves the "what if P12
shorts to something" problem.

One of the three rectangular connectors on this laptop does indeed look
as if it's both USB and ESATA. (The other two are just USB.)

I've used it _as_ USB, and it seems to work fine - the only difference
from other USB connections being that it feels slightly different on
insertion. I haven't tried it as ESATA as I don't have any (E)SATA
peripherals. (I have the odd SATA drive, but I've always felt ESATA
isn't the same as SATA.)

Yes, two in particular are Dell pc's and what's labelled eSata looks
identical to a Sata port. They're almost beside each other. I know
difference for USB btw.

So do I. This connector on my (Toshiba Portégé) laptop appears to be
_both_ - presumably to just save space. I presume it has both lots of
connections, and whatever you plug into it - either a USB type A plug,
or an ESATA cable - only makes contact with one of them.

it is easy to make up a lie, but it can take much more time and effort to
convincingly refute it. - Patrick Cockburn, i, 2016-9-24

Can someone show me a picture of an eSATA - USB connector? Is there even a
unique standard for such a thing? Just curious.

Just run a esata to sata cable to your drive. Star Tech has them
You will need a separate power cable. I do this all the time to
transfer data from old drives to new drives.

square peg, round hole.

You could always put your drive in an external carrier
with an USB interface, then run a USB cable to a usb port
on your computer

The only external carrier I like is the Rosewill RX304-APU3-35B.
Comes with a esata cable and usb 3 cable. Has a temperature
controlled fan too

For temporary transfers, I use an adapter from Star Tech.
Comes with a power supply too. Does sata, ide, usb(3)

I have 6 or so externals and portables. I also have a cable accepts old
ide and Sata drives (and I have a stack of bare bones drives to use with
it). That cable and the spare drives is what got me thinking about the
unused port on the motherboard so I asked
