A user reports that their hard drive has failed and needs to be replaced. Which of the following should the technician do FIRST?

Running a manufacturer's diagnostic tool is a verification step that comes after gathering information about the problem, not before.

Re-imaging is a corrective action that assumes the drive is functional and the problem is confirmed, not a first troubleshooting step.

Replacing the hard drive is a physical repair action that should only occur after the problem is properly identified and confirmed.

Asking diagnostic questions is the first step in the CompTIA A+ troubleshooting methodology - 'identify the problem.' This helps confirm whether the drive truly failed, understand what symptoms occurred, and gather information before any physical or corrective action is taken. Skipping this step risks unnecessary hardware replacement or data loss.
