Free Sidebar Gadgets for Windows 11/10/8.1/7 Desktop


Drives Monitor overview

Version 17.1 released at 03/01/2023

Drives Monitor is a Windows 10 sidebar gadget that provides a lot of useful information about the functioning of each physical or/and logical disk (the amount of free and used space on the disk, its loading in %, labels, reading/writing speed, the file system used, etc.). On the other hand, a real-time graph is also provided. Clicking on the drive letter opens a fly-out window where you can view detailed information about the physical drive model, capacity, type, the number of partitions, cylinders, sectors and more. Furthermore, the gadget includes an “Eject” button that allows you to safely release the USB device. Unlike other gadgets, Disk Monitor supports hidden and mounted drives. If the free space is critically low, the disk space usage bar turns red, thus letting you know about this issue and take the appropriate measures. Yellow disk space usage bar indicates low disk space. Percentage for critical and warning disk usage you can set into settings. Also in settings you can switch between physical and logical drives, exclude drive letters (or disk number in case of physical drives) from monitoring and choosing what information to display.

If you run CrystalDiskInfo in the background, the gadget can show drive temperatures and drive health status based on S.M.A.R.T. data. See Temperatures Setup page for detail.

The gadget offers easy access to disk contents, as you can open a drive in Windows Explorer by simply clicking on the appropriate background. Drives Monitor works on both 32-bit and 64-bit systems.
