DiskCheckup 3.6.1001.0 by PassMark Software is a lightweight system utility designed to read, display, and continuously monitor the S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data recorded by modern hard-disk and solid-state drives. Falling within the hardware diagnostics and disk-tools category, the program presents a single-window interface that lists every internal or external drive detected through the IDE, SATA, SCSI, USB, or NVMe bus; for each device it exposes the raw and normalized values of critical attributes such as reallocated sectors, spin-up time, temperature, wear-leveling count, and total host writes, then compares them against vendor-defined thresholds to calculate an instantaneous health score. Users typically launch DiskCheckup when commissioning a new machine to establish a baseline, schedule it to log values every few minutes during long-term stability tests, or invoke it periodically on servers and workstations to obtain an early warning of impending mechanical or flash-memory failure; the built-in alert engine can send e-mail or pop-up notifications the moment any parameter drops below its safe limit, giving administrators time to image the disk and order a replacement before data loss occurs. Additional panes display the drive’s model, firmware revision, power-on hours, and supported features, while a simple “Export” button writes the entire dataset to CSV for trending in spreadsheets or help-desk tickets. Because the application is distributed exclusively as a portable executable, it requires no installation, updates in place, and can be carried on a technician’s USB stick to audit multiple PCs on the same day. DiskCheckup is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
