A direct connection won't work

The communication protocols for SATA are quite different from those for USB. You need an active interface like this neat little toy:

Interface Adapter

by TheChas In reply to How To Create A Sata To ...

As Nick said, you cannot just wire up a cable and have the SATA HDD work over a USB interface.

First, you need to provide all of the power a SATA drive needs. That includes 3.3 V, 5 V, and 12 Volts.
Since USB only provides 5 volts, you need either an external power supply, or efficient DC to DC converters.

Then, you need data buffers and interface converters along with the support hardware for the devices.

As far as you main question about the raw connections, check out this site:

Still, what you need is a USB to SATA adapter like Nick gave you a link to.

if that adapter does not do, there are Sata -- USB external drive cases that you can purchase as well.
They would cost about the same (or more) as that cable though, but may be easier to find.
