Explanation

Drive geometry describes how a hard disk drive is logically organized for data addressing - specifically the number of heads (read/write surfaces), cylinders (concentric track groupings across all platters), and sectors (the smallest addressable units per track). This logical structure is what the BIOS and OS use to locate data, making B correct.

• A is wrong because algorithms for locating segments describe addressing schemes (like LBA - Logical Block Addressing), not geometry itself.
• C is wrong because physical platter dimensions (diameter, thickness) are manufacturing specs, not the functional addressing structure.
• D is wrong because pit depth and magnetic field charge describe storage media physics, relevant to optical and magnetic recording technology, not drive geometry.

Memory tip: Think of drive geometry like a city map - Heads = floors of a building, Cylinders = city blocks, Sectors = individual lots. "HCS" gives you the three components of drive geometry that define where data lives.
