S.M.A.R.T. API is a class library written in VB.NET (targeting .NET Framework 4.8) that demonstrates how to query and retrieve S.M.A.R.T. diagnostic data from disk drives using managed code. The library source code is fully reusable and scalable, allowing you to integrate it directly into your own .NET projects.
The repository also includes a Windows desktop application that serves as a practical implementation demo, displaying your drives' health status and diagnostic attributes in a clean user interface.
This library was built to simplify the process of executing WMI queries and parsing raw byte structures into a structured, reusable API.
Instead of writing boilerplate infrastructure code from scratch, this solution maps out the necessary WMI structures and provides pre-built properties to handle the parsing of vendor-specific RAW values into multiple bit representations (32, 48, or 64-bit), giving developers a solid starting point for hardware monitoring.
How many lines of boilerplate code do you really want to write just to extract basic hardware diagnostics in .NET?.
- Microsoft Windows OS.
- Navigate to the Releases page.
- Download the latest
.ziparchive and extract its contents to your preferred directory. - Run the executable file to launch the demo application, or grab the included source-code files to use in your integrated development environment.
This tool does not pretend to be a professional S.M.A.R.T. tool software.
Because the representation of the vendor-specific RAW values always needs further investigation, this tool has what we could consider a limitation in the meaning of being incapable to determine when a vendor-specific RAW value should be represented as a 64, 48 or 32 bit integer, because that is work of the developer itself. This is normal and understandable, because as I mentioned, this application does not pretend to be a professional tool.
For the reason being said, my implementation tries to facilitate this task by providing properties to show the RAW value in different representations.
Anyway, almost all the vendor-specific RAW values are 32-bit integer values, which is the default kind of value represented in the user-interface of this tool.
