Hi, my macbook pro has started to do something weird lately. Whenever I connect my USB, the trash can icon on the dock will show that it is full when prior to connecting the USB it was empty. When I open the trash can, it has the files on my USB in it. I was wondering if anyone knew how to fix this? I'm guessing that this means that I will not be able to delete any files while my USB is connected to my mac without deleting the files on my USB? Thanks in advance!
