Introduction

O&O DriveLED shows the read and write activity of the drives in a compact LED bar on the desktop. The bar can be positioned freely and is configured from its context menu. It is intended for anyone who wants to see at a glance whether a drive is working, without opening a diagnostic tool.

This manual explains how to get started, how to read and configure the LED bar, and what the indicators mean. Choose a chapter from the sidebar, or follow one of the links below.
