Challenge Problems
Push your limits with advanced challenges
A hard drive has 1000 sectors on an inner track and 500 on an outer track, with each sector holding 512 bytes. Calculate the total data capacity for both tracks and analyze the efficiency of their spacing.
💡 Hint: Use multiplication for capacity and compare densities.
If a disk's formatting allows it to change sector sizes, how might increasing the sector size affect the overall disk performance and efficiency? Discuss potential trade-offs.
💡 Hint: Think about file size and how it relates to sector size.
