Frequently Asked QuestionsI just received my drive and the size is somewhat smaller than what I ordered.Many of the vendors of storage products identify their drive models and capacities by using the same model number and capacity as the original manufacturer of the drive mechanism. However, these model numbers only reflect a hard drive's approximate capacity. Vendors may round down to the nearest "gigabyte" multiple, or hundreds of megabytes.Another reason your drive's actual capacity may differ from its nomenclature is that hard drive manufacturers use a slightly different yardstick of measurement than your computer does:The hardware industry measures disk capacity as 1GB=1,000,000,000 bytes. Computers calculate disk drive capacity as 1GB=1,073,741,824 bytes.If you take your hard drive size and divide it by 1074 (rounding up) you will get the approx. size in Gigabytes available on the computer.Additionally, some of the hard drive's capacity is used with formatting and driver data. This includes such essentials as the partition map, the desktop files, the drivers, and directory information.
