Be very careful using the icybox as your data backup. I bought one with USB2 and FW400 PATA box. It regularly corrupts the data, or it disappears completely. Only the folders can be seen. After copying the data, when you want to access it WinXP tells you that the drive is not formatted (which of course it was, when the data was copied). This is a terrible product, and I am sending mine back to where I bought it from. Hope this helps those who were thinking of getting one.
