i just recently bought a Western Digital 500GB My Book External USB 2 Hard Drive... I went to the Western Digital website to read the instructions. Followed it to the 'T' and continually receives error message "the specified i/o operation on \Device\harddisk1\dr4 was not completed before the time-out period expired." Also tried restarting my computer and the same message appears... any help?? i tried going to manage my disks but do not see it there
