What picture of connector for laptop hard disk SATA?

Unfortunately, there is also a "mini" or "slimline" connector for drives, which is used in some notebook machines.

Do you have a particular drive that you are replacing, so we can determine which connector it uses and which the replacement drive will need?

If'n all you want is pictures, here's a slimline: http://www.mp3car.com/newbie/132466-slimline-sata-cable-conecctions.html and here's a regular: http://www.sierra-cables.com/Cables/Images/SATA-Combo-Cable-3.jpg .
Notebook connectors tend to have the data and power in one connector as shown. I don't know if any of them use the separate two-cable connections.

I've been looking for specifications on the width of each but haven't found them yet. The easiest way to tell them apart will be to measure the width of the existing connector and compare it to the two spec widths.

Ehh, the best that I can find is on good old Wikipedia: http://en.wikipedia.org/wiki/Serial_ATA#Power_connectors
