Open Source C Hard Disk Health Check Software

Memtest86+ is a free, open-source, stand-alone memory diagnostic tool designed to thoroughly test system RAM beyond standard BIOS checks. It runs independently of any operating system, allowing it to access nearly all available memory without software or UEFI library limitations. Supporting x86, x86-64, and LoongArch64 architectures, Memtest86+ works on a wide range of modern and legacy hardware platforms. The tool can be booted directly via BIOS or UEFI, or through compatible bootloaders, making it highly flexible for troubleshooting unstable systems. It uses advanced testing algorithms specifically designed to detect intermittent, hard-to-find memory errors caused by cell interaction and hardware behavior. With ongoing development and community contributions, Memtest86+ remains a trusted solution for diagnosing memory-related system issues.

cross-platform hard drive performance benchmark

By usage of CPUFreq, ACPI, HDDTemp and internal functions, LACH daemon is able to reduce power consuption in a laptop by scaling both CPU as GPU (Radeon only), as HDD. Also checks for thermal overheat for the sake of laptop health.

LiMon (Linux Monitor) is a free/open/libre multiplataform real time Linux monitor written in C/C++, and other languages. Monitor of server's relevant aspects, such as services, temperature, CPU, memory and disk usage, etc.

Provides battery,temperature,ac,cpufreq (SpeedStep,Powernow!) control and monitoring. Proper suspend to disk/ram and standby by shell hooks that are easy to extend. APM and ACPI machines are supported equally. For laptops as well as for workstations.

Check your HDD by scanning it for hidden or latent bad sectors, diagnose problems with HDDs.
