My 80GB drive has been working fine until today. The only change I made was to share it on my home network so that iTunes on 2 computers could share it. The WD Passpot drive now does not appear in My Computer and it is not accessable. It does show in Device Manager and running WD diagnostics on it does not return errors. All of my iTune music is stored on that drive but I do not have access to it. Any ideas?
