Here's my idea: I have an old crappy PowerMac G4 here with a 40gigs in it and a spare freshly formated 20 gigs. I would like to transfer them in my main rig and put them on IDE cable since my main and single HDD is Sata. 40 gigs as master and 20 gigs as slave. Copy the content of the 40gigs to the 20gigs so i can put the old 20gigs in the crappy Mac and keep the 40gigs reformat it and use it on a windows XP pro compter im gonna use for download only. Do i just have to copy and paste or there is a special tool in Windows 7 that could help me copying the whole HDD ?
