📝 Bad blocks in Disk Management

Q1. A storage system receives logical block number 2500. The outer zone stores 140 sectors per track, the inner zone stores 100 sectors per track, and each cylinder contains 2 tracks. The first 2000 logical blocks are allocated to outer‑zone cylinders. Which cylinder number could contain block 2500?

💡 Difficulty: easy | ✅ Correct: B

Q2. Why does a disk with variable sectors per track require more complex logical‑to‑physical address translation than a disk with constant sectors per track?

💡 Difficulty: medium | ✅ Correct: A

Q3. A system reports that logical block 12345 is unreadable. The disk has 200 cylinders, each cylinder contains 2 tracks, outer‑zone tracks hold 150 sectors, inner‑zone tracks hold 100 sectors. Assuming the outer zone occupies the first 100 cylinders, which physical sector number is being accessed?

💡 Difficulty: hard | ✅ Correct: B
