Part $1$: A hard disk has four surfaces $($that$\text{'}$s top and bottom of two platters$).$ Each track has $2048$ blocks and there are $131,072(217)$ tracks per surface. A block holds $4,096$ bytes. The disk is not "zoned." What is the total capacity of this disk? Show your work. $($Hint: what is the relationship between blocks and sectors$?$ Another hint: All the numbers given are powers of two.$)$ You may express your answer as a power of two, in gibibytes, or in tebibytes if you like.$$ What's a gibibyte?
