Under properties the drive is "FAT32" I wanted to convert it to NTFS, however it will not let me do this. I right click on the drive and select format and immediatly the drive disapears and I get a pop-up stating: There is no disk in drive E: Insert a disk, and then try again. I also tried through the command line. I get the message: Cannot determine file system of drive E: The drive seems to be working fine otherwise. I can add files etc. This is driving me crazy. Anyone have a clue about what the problem may be or how I can fix this?
