In 2003 Seagate, Maxtor, Fujitsu, and Hitachi GST released a joint
"position letter" announcing that we'd start to see disks with
4-kilobyte sectors "soon". The original estimate was that such
drives would ship in 2006, but I'm reasonably certain all the 750GB
disks that I've seen have 512-byte sectors.
4K, BTW, is conveniently the size of an i386 memory page. Fair enough,
I guess; IIRC, the 512-byte standard came from the VAX memory pagesize.
 Real kilobytes, not this "but it's an SI unit" whining or
