First you have to mount these partitions, if you want to do it automaticlly add them to /etc/ fstab.
Linux can read/write to FAT32 Partitions with 99% success rate.
Redhat decided (because of legal reasons I guess) to remove the NTFS support from the distribution.
So there are 2 solutions.
The first one is to compile a new kernel and configure it to support NTFS, the second is to use and RPM from here:
Take note that NTFS partition can be read with no problems, however the writing support for NTFS is EXPEREMENTAL
and may destroy the ENTRIE FILESYSTEM
So I suggest you disable the NTFS write support if you compile a new kernel, or if you use the RPMS just mount the NTFS partition in read only mode. If you want to transfer files between the two OS you can use the fat32 partition.
