Explanation

S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) is firmware built into hard drives and SSDs that continuously tracks internal health metrics (reallocated sectors, spin-up time, error rates, etc.). When values cross critical thresholds, the drive reports an imminent-failure warning to the BIOS/UEFI, which displays it just after POST - exactly as described. CHKDSK is a Windows file-system utility run manually from the OS. eSATA is simply an external drive interface. QoS (Quality of Service) is a network traffic prioritization feature - none of these generate predictive drive-failure warnings.
