Funny, but having spent 13 years in the Industry, the only place I ever run across GiB is in posts like this. The industry uses GB. The reason for the slight difference in value is due to computing using a base-2 system and SI being base-10. Nobody uses GiB in practice. -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
