    I had a 320GB WD passport drive I replaced the drive with a 500GB WD scorpio blue.

    It's been working fine, until today...

    I thought I'd ejected it so pulled out the USB. It came up with the error message, so I plugged it back in. It reied to do a time machine back up but keeps getting stuck after about 10GB's of backup.

    I've attached an image of the error message I keep getting.

    I've tried erasing the drive, erasing then doing a disk repair (which said it needed repairing but was fine after repair)

    Not sure what else to try as it still won't back up properly

    if you boot off your install disks and then repair it or erase it again it might work. I had an external drive that had turned into a brick with cables until I formatted it using my install disks, it's working fine now!
