cant access external harddrive
I have a 320gb Western digital sxternal harddrive. Yesterday, when I turned the comp on, a red question mark appeared on the destop shortcut for the drive. I went to MY COMPUTER and found the drive was no longer listed. When I click on the shortcut for thedrive, I receive the following message :THE DRIVE OR NETWORK CONNECTIONTHAT THE SHORTCUT "EXTERNAL DRIVE F.lnk REFERS TO IS UNAVAILABLE. MAKE SURE THAT THE DISK IS PROPERLY INSERTED,OR THE NETWORKRESOURCE IS AVAILABLE, AND THEN TRY AGAIN". The drive is running, I can feel it when I touch it and it is ilit up. Anyone got any ideas??
