Tried with different cables. This particular iomega external hdd does not have a seperate power adapter. it has 2 usb connectors and I believe one of that is used for power and other for data. I can think of 2 possible issues - 1. not sufficient power supplied to the external hdd. 2 (and more likely) the OS is not able to recognize the >2TB consistently...I see lots of posts on hdd addressing limitations.
