What HDDScan is

HDDScan is free Windows software for diagnosing hard drives, RAID arrays, USB flash drives, and SSDs. Its tests include linear verification, reading, and erasing, plus Butterfly mode reading. For supported drives, it reads and analyzes SMART parameters, can run SMART tests, and monitors temperature across supported ATA, SATA, USB, FireWire, and SCSI drives. Compatible drives may also offer controls for AAM, APM, and PM settings, and commands to start or stop the spindle. Reports can be printed or saved in MHT format. The program also supports command-line use and can save generated commands as .cmd or .bat files. Listed compatibility spans Windows XP SP3 through Windows 10, with Windows Server 2003 subject to restrictions; support varies by drive and controller. RAID volumes and USB flash drives are limited to surface tests, and USB capabilities depend on program support. The maker advises running only one test at a time because simultaneous tests have not produced stable results. Erase mode overwrites tested blocks with a pattern, making the previous data unrecoverable. HDDScan is listed as free.

Good

  • Freeware for hard drives, RAID, USB drives, and SSDs
  • Reads SMART parameters and runs supported SMART tests
  • Monitors temperature on supported drives
  • Reports can be printed or saved as MHT
  • Command-line use can save .cmd or .bat files

Watch out

  • Compatibility depends on drive and controller support
  • RAID and USB flash drives have surface tests only

  • Erase mode makes prior data unrecoverable

Who it suits

HDDScan suits Windows users who want to inspect drive health, run supported tests, or check drive temperature. Users should first confirm their drive and controller capabilities and take care with Erase mode.

Verdict

HDDScan provides multiple drive checks and reporting options for supported Windows systems. Its test limits and irreversible Erase mode deserve attention before running a diagnostic.
