Open Source 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.

GSmartControl is a graphical user interface for smartctl. It allows you to inspect the hard disk and solid-state drive SMART data to determine its health, as well as run various tests on it.

Yet another cross-platform graphical process/system monitor. A customizable cross-platform graphical process/system monitor for the terminal. Supports Linux, macOS, and Windows. Inspired by gtop, gotop, and htop. By default, bottom is somewhat like a dashboard - a bunch of different widgets, all showing different things, and they all cram together to fit into one terminal. If you instead just want to see one widget, maybe you want to look at a graph in more detail, for example, you can "expand" the currently selected widget using the e key, which will hide all other widgets and make that widget take up all available terminal space. To allow for widget-specific keybindings and expansion, there is the idea of widget selection in bottom, where you can focus on a specific widget to work with it. This can be done with the mouse (just click on the widget of interest).

###### HDDtempNC has now moved to Github ###### ###### Please visit the Github project at https://github.com/viharm/HDDtempNC ###### HDDtempNC provides a script to acquire hard disk drive temperature for a target host by querying an existing HDDtemp daemon and then parse the results according to the request. See project wiki for more details, usage and code.
