Physical Disk Structure

Physical storage objects:

  • The basic physical storage device that ultimately stores your data is the hard disk.
  • When you install your operating system, hard disks are formatted as part of the installation program.
  • Partitioning is the basic method of organizing a disk to prepare for files to be written to and retrieved from the disk.
  • A partitioned disk has a prearranged storage pattern that is designed for the storage and retrieval of data.

(The book then goes into the basic disk layouts that Sun, HP-UX, AIX, and Linux uses.)
