It appears that I will have to format my thumb drives upon every use of them, once they are full - so that I can get more data on them again. There's got to be an easier way to do it.

If you delete files on the thumb drive, they'll go into the trash on the thumb drive, and thus will take the same amount of space (I think).
After you delete the files, and with the thumb drive still plugged-in, empty the trash. That should recover the space. Then you can finally eject the thumb drive.
If you were to eject the thumb drive and then try to empty the trash, it won't work, because the computer can't find the trash on the thumb drive itself.

You don't need to reformat; simply empty your computer's trash bin as suggested while the USB drive is still attached. Space is not recouped until the trash is emptied.

I know this is an old post but Just a heads up this issue tends to be caused by hidden files ( ie when you delete some files for some reason or another the files become hidden away in the trash folder but anyway the root cause is not important however the simple solution/work around is so basically we need to be able to view hidden files in the finder now you could use terminal but I wouldn't recommend that for the everyday mac user as it can cause some serious damage if you type the wrong thing into it and if your advanced enough to be using terminal then I would recommend you google how to enable hidden files in the finder using terminal.
Now for those of you who are still reading I would recommend you download invisiblix using the following link http://www.macupdate.com/app/mac/25872/invisiblix then follow the instructions on the site to install the app once installed open the app switch to show hidden files mode them open the flash drive and delete anything in the trash folder and that's it you should have now freed up the space you were looking for without the hassle of erasing the drive
Ps . Hide files / folders after you have finished because most hidden files are hidden for a reason (ie they are needed for the computer to function properly) and secondly if you are running OS X 10.8.x then you might need to hold control and then click on invisiblix then select open because of OS X 10.8.x gatekeeper feature
Good luck people

Thank you for this!...I read your comment after I had ejected the thumbdrive. However, I plugged it back in, deleted a few more items from the thumbdrive, then emptied the trash on the Macbook Pro. All free memory was then restored on my thumbdrive. YEaH! It seems that when I went back to move more to trash off the the thumb drive, it was able to find it the drive and the old trash. Thanks again
