alt Hacker NewsI'm not seeing evidence for a 1970s 1000-byte kilobyte. Wikipedia's floppy disk page mentions the IBM Diskette 1 at 242944 bytes (a multiple of 256), and then 5¼-inch disks at 368640 bytes and 1228800 bytes, both multiples of 1024. These are sector sizes. Nobody had a 1000-byte sector, I'll assert.

The wiki page agrees with parent, "The double-sided, high-density 1.44 MB (actually 1440 KiB = 1.41 MiB or 1.47 MB) disk drive, which would become the most popular, first shipped in 1986"

Firstly, I think you may have replied to the wrong person. I wasn't the one who mentioned the early diskettes point, I was just quoting it.
But that said, we aren't talking about sector sizes. Of course storage mediums are always going to use sector sizes of powers of two. What's being talked about here is the confusion in how to refer to the storage medium's total capacity.
