HDDScan review
A capable free Windows diagnostic tool with broad testing and reporting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
HDDScan is freeware for diagnosing hard disk drives, SSDs, USB storage, FireWire devices, SCSI drives, and supported RAID volumes. It suits Windows users who need local drive diagnostics, SMART analysis, temperature monitoring, surface testing, identity reports, and read/write benchmarking without a paid plan. The published requirements cover Windows XP SP3 through Windows 10, with some restrictions for Windows Server 2003.
The pricing model is straightforward: the Freeware plan provides hard drive and SSD diagnostics, SMART reports and tests, temperature monitoring, and surface testing. Its strongest area is diagnostic depth for a free Windows utility. Users can read and analyze SMART parameters, run short, extended, and conveyance tests, and perform linear verification, read, erase, and butterfly read tests. SSD SMART and identity reports add drive-specific detail, while MHT report saving and printing supports record keeping.
HDDScan also fits technical workflows through command-line support and background operation. It includes drive identity and physical-parameter reports, plus selected ATA, SCSI, power, and acoustic parameter controls. The trade-off is a narrower ecosystem: it is Windows-only and is less complete for SSD wear monitoring, remote monitoring, and integrations. Users seeking local testing and diagnostics should find the feature set well aligned with that goal; teams needing centralized oversight, broader platform coverage, or connected monitoring workflows should choose a more expansive alternative.
