Re: Can it be done?? 2Hard drives?
If I recall correctly, your laptop uses SATA drives, which are desigend for one device per bus channel. As long as only one device is connected to the channel at a time, then things should work for you (the additional connector may cause noise which could slow operations). In a nutshell, mulitple drives on the SATA channel will interfere with each other and make a hash of communications (in other words, it won't work).
The PATA drives on a typical (older) desktop had addressing lines which told one fo two drives on the bus which unit should be responding (with master or slave, which was set either manually or automatically depending on configurations and the physical cable and connectors).
Since desktop machines have plenty of room for stuff on the motherboards, there are often extra connectors and busses for mulitple SATA drives to be connected on newer machines (I have one with connectors for up to six SATA drives), whereas laptops are not designed for such flexibility.
