Windows access to APM / FAT32 partition

If I partition my ext HDD (My Book Home 1TB) using Apple Partition Map (APM) and format one (of several) partitions as FAT32, will a Windows XP PC be able to find that partition?

I want most of the drive for Mac backup and storage, but may want to use it to move files larger than my 1GB flash drive (but smaller than the 4GB FAT32 limit) or collections of many files from my Mac environment to somebody else's PC without any special software on the PC side.

Thanks!
