1. Each read-write head in a disk drive moves independently of the other read/write heads.
2. A track contains multiple sectors.
3. A sector contains multiple cylinders.

7. An extended partition can be divided into any number of logical partitions.
8. Clusters are the basic unit of storage for directories and files in a FAT-type file system.
9. If each disk cluster contains two logical sectors, the cluster size must be 4,096.
10. The cluster allocation table (CAT) keeps track of all clusters used by a file.
11. A disk containing primarily small files should use a small cluster size to make the most efficient
use of space.
12. The FAT32 file system allows the setting of permissions on individual files and folders.
