MARK--- I had to install a new hard drive in my daughter's two year old 3000 Y410. Had a Hitachi 160 GB and she filled it up. Cloned with a new Hitachi 500 GB and everything went as planned. Bought a 2.5 Thermaltake USB 2.0 enclosure for her to use the old 160 as extra storage. Formatted the 160 GB, but only 105 GB would format. 55 GB, I assume the NOVO/Windows VISTA section will not format. Is there a way to format the whole disk and have a completely clean NTFS hard drive for extra storage. There should be a way to break into the apparently locked Lenovo section. Thanks
