Well, to nitpick, they say it correctly, as for their "kilo", 10^3 bytes is correct. We, the binary folk, assert kilo to be 2^10 bytes which is actually called kibi, but we still use "kilo" in our everyday language thanks to historical ballast (and because, as I recently heard, the -bi units aren't around that long yet). First time I heard of them was in uni lecture ~2003±1. > They do this because it fudges disk sizes to appear 2.4% bigger than > they really are. > > When you get into TB drives, it gets worse as 1024*1024*1024*1024 > differs from 1000*1000*1000*1000 bu a lot more than 2.4% By 1.024^4, which is 1.0995 to be precise. Those swines are stealing almost 10% from us. :o) -- Gruß | Greetings | Qapla' I forbid any use of my email addresses with Facebook services. “Don't put multiple statements on a single line unless you have something to hide.” – Linux Torvalds, Linux kernel coding style documentation
