Explanation

The traditional hard disk sector size is 512 bytes, a standard that has existed since the early days of magnetic disk storage. This is the foundational unit of data storage on a hard drive - the smallest addressable block the disk controller reads or writes. While modern drives may use 4,096-byte sectors (Advanced Format / 4K sectors), the classic and exam-expected answer is 512 bytes.
