# ReleaseDisk

## 1. API Description

This API (ReleaseDisk) is used to release a disk.

{% hint style="info" %}
**Notes**

* A system disk cannot be released. It is released together with the deletion of the instance.
* For a regular account, a disk is released directly after the deletion. Calling this interface on a disk in the recycle bin releases it completely.
* This operation is irreversible, so please proceed with caution.
