Microsoft and also memory RAM manufacturers calculate 1 Gigabyte as 1,073,741,824 bytes (Binary Numeral System). The difference between the 2 methods is around 7%. So you have to subtract 7% of the advertised capacity of any HDD, SSD, or USB Flash drive in order to get the usable capacity after formatting. m 0 l drdenby January 22, 2014 1:11:01 PM Thank you for this RulesSpew, RealBeast, Dereck.
