Yesterday i backed everything up ready for the format i did today on my USB 120GB FreeCom drive. After the format, i put my HDD in and it loaded up fine, and ran SP1 for Vista from it. Now, after that completed, whenever i reconnect the drive to my PC, the light on the HDD comes on and i can hear it spinning, but windows simply doesnt register it. No *ding* noise, nothing. Ive tried it on 2 other PC's and both have the same outcome. Please tell me this drive isnt dead, its got absolutely everything on it (including my GTA IV 100% save !) 

(Guess im a total noob with these things). Connected it up and everythings still there thank god
Must be a faulty USB connection then. Thanks !
