Older BIOSes don't understand that hard disks now can have 4KiB sectors, so some of the "advanced format" hard disks report a sector size of 512B. But behind the scenes, the hard disk maps the logical sector to a subsector of the physical sector. The only sure fire way to find out if your hard disk uses 4KiB sectors is to open your computer and eyeball the hard disk. All 4KiB hard disks that I know of have statements on their surface that tell me so. Rgds,
