I've got a WD passport drive that I formatted for HFS+ or whatever it is and used it on my macbook pro. whilst copying files from it to an ipod whilst time machine backed up it decided to disconnect itself for no reason and then ruin itself and not be recognised at all by my mac anymore. it spins up etc light flashes but it does nothing and nothing shows up on my mac. ive managed to get all the files off it using HFSExplorer on my pc (but the drive is not properly recognised by my pc and does the 'found new hardware' whenever it is plugged in) so the drive hasnt died. I can't think of a way reformat it to get it working again. How can I reformat this drive using my PC or mac and free software, dont want to have to shell out for a HFS reader thingy. Cheers.
