When i try and copy to the flash drive it will only copy about 13 GB worth of data. I tried copying MP3 and then PDF files. It is a 32GB flash drive so i know there is space. I tried using a different flash drive and it did the same thing. I tried formatting to fat32 and it did the same thing, so i tried formatting it to efat, and it did the same thing. Tried formatting to NTFS and the computer wont let me. I tried using a different USB port and it did the same thing (it was the ones on the front, havent tried the ones on the back of the computer)
