A user has a nonfunctional computer that has two hard drives. The user needs to retrieve information from one of the drives. Which of the following would be used?

Options

AReformat bad hard drives
BExternal enclosure
CReformat all hard drives

Explanation

An external drive enclosure (or external hard drive dock) allows you to remove a hard drive from a non-functional computer and connect it to a working computer via USB, eSATA, or Thunderbolt. This gives the working PC access to the drive's files without needing the original system to function. Reformatting (options A and C) would destroy the data the user is trying to recover. CHKDSK and DEFRAG are utilities run on drives connected to a functional system - CHKDSK repairs file system errors and DEFRAG optimizes file placement, but neither helps retrieve data from a drive in a dead machine, and using them first risks further data loss.
