Well, calling it mb (millibyte) is clearly wrong. And the value of 
1.44Mbytes assumes you take 1Mbyte as 1000*1024 bytes, which is downright 
crazy.

But I'll bet you're moaning abotu the '720K single-siderd' part. But what 
do you think is the capacity of a single-sided, 80 cylinder disk using 
the the HD data rates (And thus 18 512-yte sectors/track)? OK, I'll but 
that's not what the drive supports, but there's no logical reason why it 
can't...
