my passport is partitioned into 2: time machine and just storage (Mac OS Extended [Journaled]). after moving a couple files back and forth between my mac and the storage partition, and then installing bootcamp using an ISO file from the storage partition, my passport hard drive says i only used 4GB total out of the 199GB storage partition. However if i go to the individual files they are well > 100GB total. and when i tried to add more files it said "full". I have no idea/hit dead-ends on searches for what to do next. I have been using my hard drive on the macbook Air, Mid-June, and i tried it on another MBP and the same thing happened. Thank you for any help.
