HDDScan is a powerful freeware tool designed for the diagnostics and maintenance of various storage devices, including hard drives, RAID arrays, USB flash drives, and SSDs. This versatile program can test your storage devices for errors such as bad-blocks and bad sectors, read S.M.A.R.T. attributes, and modify specific HDD parameters like AAM and APM. HDDScan is invaluable for users who wish to monitor their drives' health, predict potential failures, and prevent data loss by backing up their files in time. It also functions as a hard disk temperature monitor and provides benchmarking capabilities, displaying performance graphs for every test conducted.
Key Features of HDDScan:
Supported Storage Devices:
- IDE (ATA) and SATA HDDs: Diagnose and monitor standard hard drives.
- SCSI (SAS) HDDs: Support for enterprise-grade storage systems.
- External USB Drives: Compatible with all major USB enclosures.
- FireWire (IEEE 1394) HDDs: Ensures broad compatibility with various storage connections.
- RAID Volumes: Perform surface tests on RAID volumes built from ATA (IDE), SATA, or SCSI HDDs.
- USB Flash Drives: Conduct surface tests on pen drives.
- SATA/ATA SSDs: Diagnose and monitor solid-state drives.
Storage Device Tests:
- Verification in Linear Mode: The fastest way to check if your drive needs data recovery, has recoverable errors, or is in optimal condition.
- Reading in Linear Mode: Similar to verification but also transfers data to the host, allowing you to confirm data integrity.
- Erasing in Linear Mode: Securely erase data across the storage device's surface.
- Reading in Butterfly Mode: A synthetic random read test that assesses the drive's ability to handle non-linear access patterns.
S.M.A.R.T. Features:
- S.M.A.R.T. Parameter Analysis: Read and analyze S.M.A.R.T. attributes from ATA, SATA, USB, and FireWire HDDs to monitor the drive's health.
- Log Pages from SCSI HDDs: Access and analyze log pages from SCSI drives to gather detailed diagnostic information.
- Running S.M.A.R.T. Tests: Execute built-in S.M.A.R.T. tests on ATA, SATA, USB, and FireWire HDDs.
- Temperature Monitoring: Continuously monitor the temperature of ATA, SATA, USB, FireWire, and SCSI HDDs to prevent overheating.
Additional Features:
- Identity Information Analysis: Retrieve and analyze identity information from ATA, SATA, USB, FireWire, and SCSI HDDs to confirm device details.
- Parameter Modification: Adjust AAM (Automatic Acoustic Management), APM (Advanced Power Management), and PM (Power Management) settings on ATA, SATA, USB, and FireWire HDDs.
- SCSI Defect Reporting: Access defect information specific to SCSI HDDs for detailed diagnostics.
- Spindle Control: Start or stop the spindle on ATA, SATA, USB, FireWire, and SCSI HDDs as needed.
- Report Generation: Save diagnostic reports in MHT format for easy sharing and future reference.
- Print Reports: Print detailed reports directly from the application for physical records.
- Command Line Support: Execute HDDScan functions via command line for automated diagnostics and scripting.
- SSD SMART and Identity Reports: Access SMART attributes and identity information specific to SSDs for targeted diagnostics.
