One issue is that it comes with an 80Gb hard drive which if i wanted to do a dual boot with XP and 7 isn't really enough, the hard drive inside the tough book is held in a spongy shock proof, heated enclosure, but the hard drive itself looks like a fairly ordinary hard drive:

these are the pins on the end of it:

I have two spare hard drives at home, one is a 160Gb taken from the old netbook, the other is a 320Gb taken from my macbook, both have this sort of connector on the end:

There seems to be adapters available that allow it to accept a Sata hard drive into the original enclosure, but also devices that hold a hard drive where the DVD drive goes:

Can a computer use 2 hard drives with a different operating system on each?
