Re: Can I use my laptop as an external drive?
Do both PCs have network cards? That's where you'll need to start. Both PCs need network cards and Cat5 patch cables. Then you'll need a switch. You could use a crossover, but then you wouldn't be able to add to your network in the future. Once the hardware is in place, then it's just a matter of setting the appropriate TCP/IP settings, enabling Network Discovery and File Sharing and setting up the shares.
But I'm trying, Ringo. I'm trying real hard... to be the Shepherd.
