My USB thumb drive won't update the amount of free space

My USB thumb drive won't update the amount of free space. It's constantly saying it is full, even if I delete the files on it.


It's the same on all of the thumb drives I use.


It there a "refresh" button - to get it to update the amount of data on it?


I transfer large video files between an iMac and PC computer.


Any suggestions?

iMac 2.66 GHz Intel Core 2 Duo, iPhone OS 3.1.2, Mac OS X Lion 10.7

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).


Solution:

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.
