Formatting External HD for Use with Boot Camp Windows

[Gryfon19]

So I've partitioned an external hard drive using Disk Utility. Each partition is in the right format and the Mac partition works fine. However, when I go in to Windows to format the Windows portion to NTFS, I get an error message when right-clicking the drive and selecting Format. The error basically tells me that I can't do anything because the drive is in use. I have no idea what I'm doing wrong, but I was following the directions and seem to be very close. Any ideas? Thanks!

I would simply format the window portion in FAT32 from the Disk Utility. If u don't have files over 4Gb, you wont nocice a thing

Is that 4GB per file, or folder, or application, or what? Thanks.

It's per file.
