if i want to ghost an 80 gig hard drive, do i need an 80gig partition or just one larger than the total amount of data on the drive. i have norton ghost 2003.

my new dell has an 80 gig & i want to ghost it regularly so if i get a virus or it crashes, i can recover it quickly. i just bought a new 160gig that i'll be adding as a slave drive.

thanks!!!
