I love that for the next few years they were commonly called Winchester drives due to IBM's original naming in the early 70's.
As I recall 8 inch class HDD (5, 10, 20MB?) were called Winchester in the pre-PC/XT era, named for the earlier IBM product, and then the terminology carried on into the microcomputer/desktop world when the 5.25" full height HDD was introduced for the XT.
My dad still called it "Winchester" well into the 80s. I remember when we got our first "Winchester", a 20MB hard drive.
