Western Digital
www.wdc.com has one. I don't remember it name, I have it install on my XP partition... I'm in Linux and running out the door (fear of running Windows does that to me). I think it is their lifeguard tools. I can look it up when I get home tomorrow.
I used it to copy data to a Maxtor drive (which also has a similar tool, I think), it complained that I was imaging to a non-WD drive, but did it anyway.
Try other drive manufactures web sites, as well.
