Question

A workstation is making a loud clicking noise that is originating from the hard drive and it is not booting. Which of the following should the technician do FIRST?

Options

AVisit the hard disk vendor's site and run a hardware check on the drive.
BPut the hard drive in another system and back up all data from it.
CRun CHKDSK immediately and replace the drive if it is bad.
DFormat the drive and restore from a previous image.

Explanation

A repetitive clicking sound from a hard drive - commonly called the 'click of death' - indicates imminent or active physical failure of the drive's read/write heads or actuator arm. The drive could fail completely at any moment, so data preservation is the top priority. The technician should immediately move the drive to a working system and attempt to recover as much data as possible before it becomes unreadable. Running vendor diagnostics (A) or CHKDSK (C) puts additional stress on a failing drive and risks losing data. Formatting and restoring from an image (D) destroys existing data entirely. Data backup always comes first when physical drive failure is suspected.
