he sure can.
option 1)
get a program like norton ghost and make an image, then move image to new drive
option 2)
theres lots of free programs out there (the one i used once is called 'file copy' ) that let you move every file from your primary drive to your new one set as slave, then you simply unplug the old drive, set the new one up as primary master, and you're off
let me know if you need help finding a link to 'filecopy'
