Can I use the Disk Util program included with Mac to format my External with FAT32

I was using my external hard drive with my mac and its formatted in the MAC HF(something like that) file system. I would like to format that external hard drive such that the file system is either NTFS or FAT32 so that I can use it on my windows partition running on boot camp. I am asking this question since I am planning to get a new HD for my mac and use the old one with windows.

Thanks

In disk utility, select the disk on the left, then go to Partition, and select "MS DOS File system". This makes it a Fat32 file system. To make it NTFS you will need a Windows system. You can also do this with the "erase" tab in Disk Utility.
