HDDScan
What it is
HDDScan is free Windows software for diagnosing hard drives, RAID arrays, USB flash drives, and SSDs. It provides linear verification, reading, erasing, and Butterfly-mode reading tests. For compatible drives, HDDScan reads SMART parameters, runs SMART tests, monitors temperature, and can change AAM, APM, and PM settings or start and stop the spindle. Reports may be printed or saved as MHT files. Command-line use is supported, with generated commands savable as .cmd or .bat files. Listed compatibility covers Windows XP SP3 through Windows 10, plus Windows Server 2003 with restrictions, although drive and controller support varies. RAID volumes and USB flash drives support surface tests only, and USB capabilities depend on program support. The maker advises running only one test at a time because simultaneous tests did not produce stable results. Erase mode writes a pattern over tested blocks, making previous data unrecoverable. The download page lists [email protected] and names Artem Rubtsov as author.
