A couple of years ago, this was a huge problem. Iomega tech support would ask that the phone be held close to the drive while it was making the noise, and then would transfer me to the RMA department, where the drive was replaced, no questions asked, although they did not make it commonly known that they would do this. It was a serious quality issue, and Iomega typically replaced the drive, in warranty or not. Demagnetized disks... what a load of cr@p!
