Clone HDD to new HDD?

Hey guys I'm hoping you could help me. I built some computers for the local Verizon stores a while back and the guys have pretty much destroyed them. I would like to set up one system and clone the drive so that all four systems are identical. Each system is completely identical to the next as far as hardware goes. Can anyone suggest a high quality program to duplicate the first drive that is simple and quick? Time is very important as the systems cannot be down for to long. Thanks in advance.

I'd go with CloneZilla on this...

Do any of them have any advantages over the other?

Buy your HHD from WD and
get a copy of Acronis for free.

Their actually all WD HDD's

There you go

I'll give it a shot. Thanks.

unfortunately I can't use the WD Acronis as no matter what Do it says I do not have WD drives installed. I don't understand why as EVERY single HDD I have is WD (all 8) and yet not one is recognized by this program, not even the week old 2TB Caviar Green I just installed on my HTPC will pick up. I think I'll try clonezilla.
