# Delete a disk

Deleting a disk removes it and everything on it for good, and stops billing for it. A disk is billed
from the moment you create it until you delete it, mounted or unmounted, in use or idle. Delete a
disk you have finished with.

## Before you begin

- Permission to delete datasets in the project. A Member gets it through a policy that allows deleting datasets.
- Copies of anything you need, such as in [TIR Object Storage](/tir/tir-object-storage/). Deleting a
  disk is permanent.
- The disk unmounted. You can delete a disk only after you unmount it from its instance or Virtual Machine.
  See [Unmount a disk from an instance](/tir/tir-block-storage/how-to/unmount-a-disk-from-an-instance/).

## Delete the disk

1. In **Block Storage (Disk Dataset)**, find the disk's row.
2. Under **Actions**, select **Delete Dataset**.
3. Confirm with **Delete**.
