In their own words
HDD Health Monitor
HDD Health Monitor is a free, open-source Windows utility that reads raw S.M.A.R.T. information from physical drives. It shows per-drive health and estimated performance percentages alongside a complete S.M.A.R.T. attribute table. The program scans drives automatically, monitors multiple drives at once, and gives each one its own tray icon and alerts. Notifications can cover temperature, declining health, predictive failure, reallocated sectors, uncorrectable errors, and NVMe critical warnings. While running, it records health and selected attribute snapshots every five seconds and keeps history on disk between sessions. Supported drive types include ATA/SATA, M.2 SATA, NVMe, USB, and SCSI, although available data depends on the drive and controller. USB drives appear shortly after connection and disappear from the selector when unplugged. The standalone executable needs no installer or dependencies, but administrator privileges are required. It supports Windows Vista through Windows 11 and can save a PNG screenshot. The MIT-licensed software costs nothing.
