They both are seen by my Windows 7 system and I have copied between 8GB-16GB worth of files back and forth between my dual internal hard drives and both external drives. Please put out the correct information so that the people who know less about computers will be directed in the right direction instead of becoming more confused...

You and pparks are talking about 2 different things pparks is right that you cannot write records larger than 4GB to a Fat32 disk. You would hit that limitation e.g. when you do File Backup with the Windows facilities. That has happened to me even on an XP system.
You can, however, write files of any size to a Fat32 disk if the individual records are no larger than 4GB. That would normally be the case if you copied a picture or documents, etc. file.
So the fact that you were able to copy large files does not disprove the 4GB limit that pparks was referring to - and the system DOES write records larger than 4GBs.

I'm not wrong at all with regards to FAT32. As I stated clearly in my post

You cannot have a single file in excess of 4GB on a FAT32 drive. A backup file from a backup system can easily be 10, 20 or 30GB in size. And thus as 1 file cannot be stored on a FAT32 drive. Here is a link describing limits of the FAT32 file system, last bullet shows a max file size of 2 raised to the 32 power - 1 byte; http://support.microsoft.com/kb/314463
