VSO Inspector is a free, legacy diagnostic utility designed explicitly to report hardware information and monitor the health of optical drives (CD, DVD, and Blu-ray readers/writers) and their media. Developed by VSO Software, it is a niche diagnostic application rather than a general system hardware monitor (like CPU or GPU temperatures). Core Features
Optical Drive Diagnostics: Detects and displays detailed hardware specifications including vendor name, model, firmware version, buffer size, and region codes.
Feature Mapping: Details exactly what your drive can do, such as which media formats it can read or write (CD-R, DVD+RW, BD-R, etc.) and its maximum read/write speeds.
Media Inspection: Analyzes inserted blank or burnt discs to reveal the exact media manufacturer, media ID, capacity, and supported burning speeds.
Sector Scanning & Sector Mapping: Features a dedicated “Scan” tab that performs surface scans and file tests to find read errors, bad sectors, or defects on a burnt disc.
Compatibility Verification: References a database to cross-check burn success rates, ensuring your specific brand of blank media is highly compatible with your burner. Current Status & System Compatibility
OS Support: It is natively compatible with older 32-bit and 64-bit Windows operating systems (such as Windows XP, Vista, and Windows 7).
Software Age: The utility is a legacy software that has not seen major updates in several years, though the final versions (like version 2.1.0.6) are still hosted on freeware archives like TechSpot and Free-Codecs. Modern Alternatives for General Hardware Monitoring
Because VSO Inspector only focuses on optical disc hardware, you will need different free utilities if your goal is to monitor overall PC component health:
