I'm having a problem with my external hard drive when using it on my linux system. I am running ubuntu with kde, and I have a 1tb hard drive (formatted in ntfs, I think). I was working perfectly when I was using it on a windows machine, on windows xp up to 8.1, but when I plugged it into my linux pc, all the files were different. Instead of the files that were meant to be on the hd, it was appearing with folders like bin and boot, like a linux system drive. After unplugging it, I plugged it into my windows pc, where it could not be seen, not at all, despite working fine before plugging it into linux. I had the same problem with a 4gb flash drive. Please help, as I need the files on that external hard drive.
EDIT: External hard drive doesn't work on my pc running windows 8.1 either, but is still seen by linux. Files still display differently, though.
