Older BIOSes don't understand that hard disks now can have 4KiB sectors, so |
14 |
some of the "advanced format" hard disks report a sector size of 512B. But |
15 |
behind the scenes, the hard disk maps the logical sector to a subsector of |
16 |
the physical sector. |

The only sure fire way to find out if your hard disk uses 4KiB sectors is |
19 |
to open your computer and eyeball the hard disk. All 4KiB hard disks that I |
20 |
know of have statements on their surface that tell me so. |
