HDDScan
HDDScan is freeware for diagnosing hard drives, RAID arrays, USB flash drives and SSDs on Windows. Its tests include linear verification, reading, erasing and Butterfly-mode reading. For supported drives, it reads and analyzes SMART parameters, runs SMART tests and monitors temperature across ATA, SATA, USB, FireWire and SCSI connections. Compatible drives may expose AAM, APM and PM controls, plus spindle start and stop commands. Reports can be printed or saved in MHT format. Command-line use can save generated commands as `.cmd` or `.bat` files. Listed requirements run from Windows XP SP3 through Windows 10, with Windows Server 2003 subject to restrictions. The plan is free. RAID volumes and USB flash drives support surface tests only, and USB capabilities depend on program support. Only one test should run at a time. Erase mode overwrites tested blocks, making previous data unrecoverable.
