A user's computer displays a S.M.A.R.T. error during boot-up. What is the FIRST action a technician should take to prevent data loss?
Flash the BIOS
Run Windows Startup Repair
Replace the CMOS battery
Back up important data from the drive
Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) is a monitoring system in hard disk drives and solid-state drives that detects and reports on indicators of drive reliability, with the intent of anticipating hardware failures. A S.M.A.R.T. error reported by the BIOS during the power-on self-test (POST) indicates that the drive is at imminent risk of failure. The most critical and immediate action is to back up all important data before the drive becomes completely inaccessible. After securing the data, a technician can proceed with running diagnostics to confirm the failure and then replace the faulty drive. Flashing the BIOS, replacing the CMOS battery, or running Windows Startup Repair will not resolve the underlying physical hardware issue with the drive.
