Library computer messed up my drive
Let me explain what's going on. When I plug my USB hard drive into a library computer, it allows me full read and write permissions, but only until I unplug it. After I unplug, I can't modify or delete the files and/or folders. All the computers in the library run Windows XP Professional. I think the problem has something to do with read write permissions between all the computers in the library, because all the file and folder names on the drive have a blue font color instead of the usual black.
