No hidden partition. Just marketing likes to report the larger decimal
numbers rather than the smaller binary numbers.
For clarification from Seagate propagandists see this article:
http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=194563&NewLang=en
It includes this paragraph. Pay particular note to the last sentence :)
"Often when two or more people begin discussing storage capacity,
some will refer to binary values and others will refer to decimal
values without making distinction between the two. This has
caused much confusion in the past. In an effort to dispatch this
confusion, all major disk drive manufactures use decimal values
when discussing storage capacity."
I guess Hitachi is not a "major disk drive manufacturer". ;)
