Ubuntu :: Can FAT32 Partitions Cause File Browser Trouble?

I have just recovered my desktop Ubuntu system, thanks to SuperGrub, and Larryfroot, who pointed me to it. It had crashed due to an incomplete install to a pen drive, but prior to this I had made some changes to my partition layout, and now if such moves could cause the problems I'm having now.I wanted to be able to access my pictures, music, and projects while testing different Linux distros from CD or pen drive (DreamLinux looks much like the Mac interface, which I like, it's rated for speed, gotta try), but I've not been able to do that from any which I've tried yet. I learned somewhere that replacing the unused bulk of the OS partition with a big FAT32, and moving your files to that drive should make them accessible to most systems. I just viewed my files from the DreamLinux distro CD, so it seems to be working. I knew the action on this type of partition would be slower, and it really is when I move files to it, so is there a better way to get what I want than this?I have since had the following annoyances from Ubuntu's Nautilus file browser, and am wondering if the drive changes had anything to do with the following:

1. I am getting error messages when I try to move files to this drive through the Nautilus GUI file browser, but then these errors are wierdly negated when the file transfer is performed anyway. Well, I should be happy that it does what I ask, but where are these false error messages coming from?

2. It gets even more strange - when viewing files on Fat32 through Nautilus, in my Ubuntu hard drive partition, the file window has a banner which states "These files are on a Picture CD". Huh??? I know where I moved my files to, and they are not on CD! What is a "Picture CD" anyway?

Can anyone find a logical explanation for these weird messages, or does it look as much to you like corruption damage?
