Yes you can.
If they are fat/fat32 partitions you can mount them with :
mount -t vfat /dev/hdx /mnt/windows
Where, /dev/hdx is the name of the harddrive you want to view and /mnt/windows is the place it will put it.
If you want to see NTFS... then first check and see if it is supported :
cat /proc/filesystems -- look for ntfs
If it isn't there, install the ntfs support rpm from :
http://linux-ntfs.sourceforge.net/info/redhat.html
Then reboot... and use:
mount -t ntfs -r /dev/hdx /mnt/windows
to load it up.
The -r is for read-only... NEVER EVER EVER EVER UNDER ANY CIRCUMSTANCES omit that -r. Writing to an NTFS partition under linux will destroy the ntfs.
You can add useful commands to mount... checkout man mount... or post again
If you want to mount more than one windows drive make many directories under /mnt (eg: windows1, windows2, windows3) and change the mount commands appropriately.
