i have 2 computers, 1 is a gateway the other a dell.. both are in good shape but the dell has a 40gig hd and the gateway has a 160gig hd.. my question is im wanting to put the 160gig hd into the dell but i dont want to lose anything that is on the 160gig hd when i remove it from the gateway.. the bigger hd has all my programs and xp home os so how would i go about putting the bigger hd in the dell and still have every thing working like it does in the gateway now...thank for any advice
