Hi to all!

Please squem solder sata conector in pcb..

Where can I find the adapter? (usb-sata-pata) know in pc3k UDMA has ... to buy just the adapter

[dobrevjetser]

There is no such adapter. You have to do modifications yourself.

The underside of the board has the USB-SATA bridge chip. The two long pairs of capacitively coupled tracks are the SATA Tx/Rx pairs.

If the chip is a JMicron JM20339, then see this reference design for pinouts:

Thanks for help!
Look chip.

I guess you know what to do. However, for those that don't, you need to remove the four coupling capacitors, and run four individual wires from the MCU side of each capacitor to a SATA connector.

Remove these capacitors?
Squem PCB?

Sorry, the schematic was for a JM20329 which has a different pinout. However, the principle should be the same for the JM20339.

I have identified the capacitors here:

I believe the pins should be laid out in the same order (or reverse order) as the SATA connector:

In fact, here is a reference design for the JM20339:

... and a datasheet:
