Wasn't really too sure where to post this, so being a Western Digital Passport 320GB external HDD I've posted it here. Had this now for a year or so I think and have been using it regularly without any problems. A couple of days ago, tried to connect to my PC via the USB and it comes with the message, driver software installation failed... followed by, device has malfunctioned and is not recognised by Windows 7. At a bit of a loss here, tried on an XP machine, same message and with another USB cable. All drivers etc are upto date. Drive is not being recognised by Windows 7 disk manager either. Unfortunately, I was in the process of backing up my media and data so had a few things which were not backed up elsewhere!! So really would like to get to the bottom of this? I fear it may have given up the ghost?! Any ideas? Thanks.
