Hi I recently bought a new macbook 13" (first time ever using mac so i dont know much yet) and have been trying to copy some of my files from my pc to my macbook using my USB flash drive, however everytime i try to copy a file from the usb to my macbook i got the message: "The operation cannot be completed because you do not sufficient privileges for some of the items." After clicking ok to this message the copying status bar doesnt move and the estimated time remaining displays nothing even after waiting for ~1hour. I tried going to Applications/Utilities/Disk Utility to repair disk permissions but the option is greyed out on my flash drive. I have also tried reinstalling osx but this seemed to just be a big waste of time. Any help would be greatly appreciated!
