There is a friend who hasn't used the U disk to come over. COPY has not been used under the 2003 system. It has discovered that the system can identify but do not list this in the list. It is a bit trouble. Here is my solution, I hope to give I will not pick up my friend:? My computer === Anti-key management === Disk management ==== In the newly discovered "Status (activity)" device icon, click Right click, select "Change the drive number And Path (C) ", then click Add === Assign the following drive number (default) === OK? Then you have this disk in my computer list ~` `
