Help me save a troubled external hard drive! I'm using OSX and I'm fine with wiping it out and starting over. This may be complicated?

I'm one of those crazy people who back up everything. And, as luck would have it, the troubled hard drive is my backup HD, so there's nothing on it I need to save. The drive in question is only 2 years old. It's a Seagate Free Agent something or other USB drive.
Problem: I can't reformat it in Disk Utility. In the First Aid tab, doing a Repair Disk shows that the disk is fine. But if I try to erase the disk, Disk Utility gives me an error, saying "Couldn't Unmount Disk"
I even tried restarting from the Lion recovery partition (or whatever the heck that's called) and using Disk Utility there. No luck.
All I want to do is erase the HD and zero out all data so the drive will check to make sure everything works and cancel out any bad sectors, and then I want to partition this huge drive into 4, to match the 3 drives I'm backing up plus a scratch drive.
If I absolutely have to for some odd reason, I can use a Windows XP netbook to help this process, but I never use that thing, so I have no experience with XP nor software other than XP itself.
