The drive has a 7.45 GB capacity and says it has 1.80 GB free. When I select all the folders in it there total size is 51.5 MB on disk (yes I remembered to show hidden files). I use to get the error that the disk is not working correctly and I clicked "fix and scan for bad sectors" and it did so and came back with no errors. It use to be used for ReadyBoost but I disabled that and I can't figure where all the space went
