I have been using a Lexar 8GB jump drive for some time. However, I now note that the free space is very much less that the total less the visible files. The MS-DOS (FAT32) Get Info shows Capacity of 7.86 GB and Available of 1.38GB (see attached screen shot). The Finder display for the Jump Drive shows only a relatively small total (see attached screen shot). If there is a hidden file system, where does one find it, and what does one have to do to delete the contents (assuming that the contents are not fulling some vital function)?
I need to use this Jump Drive for the READYBOOST function on my Windows 7 system under Boot Camp for my MacBook Pro mid-2012 laptop under OS 10.9.5 (Maverick).
