Need some help trying to wire up a SSD (Micro SATA) to my eSATA port.

So I have an STEC MACH8 SSD (has a usata/micro sata connector).
I want to solder it directly to my eSATA port so I can use it as a second internal drive.

The problem is, it needs 3.3V to run. I don't know where the best place to get 3.3v is.

Can someone suggest an option?

EDIT: I could try getting 3.3v from an unused miniPCIe slot, would that be a good idea?

Hard to find the esata pinout, the best I could find was this:
eSATA Extension Cable Internal to External Extension

And for the micro sata connector:
MICRO SATA conector 7+9 ( pinout ? )

My other question is would it be ok if I didn't connect the following pins to anything:
P2 V33 3.3 V Power, Pre-charge (don't know what this is for).
P5 V5 5 V Power, Pre-charge4 (don't know what this is for).
P6 V5 5 V Power4 (would I really need to connect it to 5v when the drive only needs 3.3v?).
P7 R Reserved5
Key
P8 Optional Vendor specific6
P9 Optional Vendor specific6

So if anyone can help, would be greatly appreciated

 

You can get good pin out at this link. The esata is wired the same as the sata data pin out.

Serial ATA Bus Pin out [SATA], SATA Pinout, SATA Signal Names

I can confirm on my laptop that all power connections are made except 11, 13-15. which are left open.

The precharge has a longer pad so it connects before the shorter, thus that's why they call it precharge, it's needed when hot swapping to safely add power to the device. I would make the connections as specified.

As far as getting power from the minicard you need to be careful that you don't have a switched power to the connector. Of the two slot in my computer one is switched one is not.

Edit: P1 through P6 connect, try leaving P7-P9 unhooked and it should work.

Hope this helps

 

Thanks, I tried it today, but I must have soldered it bad. The notebook wouldn't POST (even after I removed the SSD).

I had to clean up all the solder, took a while. Notebook is working now but I have to try it again.

It's very hard to solder when things are so small.

I might give up and just put the SSD in the optical bay.
