Seagate has made a settlement with the State of California in a class action suit regarding the nomenclature used for the GB. Yes, that 80GB HDD you recently bought isn’t really 80GB. Now, when is a Gig a Gig?
Apparently this lawsuit is based on two interpretations of what a GB is. From our experience in computer class a KB is 1,024B; an MB is 1,024KB; and a GB is 1,024 MB or 1,073,741,824 bytes. However, hard drive manufacturers used 1,000 instead of 1,024 so that a HDD listed or marked as 80GB is just actually 74.5GB. That’s 7% below actual reported capacity.
Now, anyone who bought a Seagate hard drive in the US between 22 March 2001 and 26 September 2007 could be entitled to a five per cent (5%) discount on future Seagate products or free backup software according to The Register.
This settlement is only in effect in the US though and I don’t see Seagate changing this nomenclature any time soon. The Seagate Hard Drive Settlement website can be found here.
