again... so i had issues with my lacie HD, and it has been a bit of a bitch since then. so i have replaced it tonight. i replaced it with a Comstar USB 2.0 Mobile HD. it doesnt require an ac plug, just used 2 usb ports. i plugged it in, popped up fine. But when i tried to drag something to it, it says: "The item could not be moved because "new volume" cannot be modified" any suggesions ???
