Disk Identity

Written by John Harris, Updated on October 12, 2023

Every hardware device in a computer has its own unique identity, which allows it to be recognized distinctively. Similarly, a disk also possesses a unique identity that enables the computer to recognize it exclusively. The Disk Identity is presented in the form of a string composed of alphanumeric characters.

There are two types of Disk Identity: the Instance ID and the Hardware ID, and these IDs often cause confusion among many users.

  • Hardware ID: This is a unique identifier established by the vendor during the manufacturing process. Windows operating systems use this ID to match the device to the appropriate INF file. The Hardware ID is highly stable and not easily changeable.
  • Instance ID: This ID is a system-assigned device identification string. It remains persistent only until a system restarts, and it changes when you format the partition.

Various third-party applications can be used to retrieve the Disk Identity, but you can also obtain it through the command prompt and by navigating the control panel. While many users may not be familiar with Disk Identity, there are numerous benefits to using it.

In online multiplayer games, servers implement anti-cheat mechanisms that can ban cheaters from the server based on the Instance ID. However, this identity can be temporarily altered using third-party tools. Imagine a scenario where your computer lacks the necessary drivers for a device, rendering it an unknown device to your computer. You may have struggled in your search for the specific driver without much success. In this situation, by obtaining both the Hardware ID and Instance ID, you can make your search more focused and efficient.

To retrieve the Hardware ID and Instance ID, follow these steps: Device Manager --> Right-click on the unknown device --> Select Properties --> Go to the Details tab --> Under the property section, select Device Instance Path.
