I recently purchased the 320GB 7200rpm Lacie Rugged Hard Drive. I'm having an issue where when I put something onto it that say is 2GB and it brings my memory from 200GB to 198GB when I go to remove that 2GB file my memory still reads 198 and constantly depletes when I add and then remove files. I've had this problem before with a flash drive of mine, where I had to keep reformatting, but I shouldn't have to do this with my new hard drve. I'm formatted To Mac OS Extended (Journaled). Any advice or thoughts would be greatly appreciated
