# Replacing a Drive

You might want to replace a drive if the drive shows signs of failing. Before you start this operation, be sure that an available unconfigured good replacement drive is available. The replacement drive must have at least as much capacity as the drive you are replacing. Perform the following steps to replace a drive.
Attention: Make sure to back up the data on the drive before you replace it.

1. Navigate to the Controller dashboard, and click a drive group name (for example, DG_1), then click the icon that corresponds to a drive group to display its contents.
   The virtual drives and physical drives associated with the selected drive group appear.
2. Click the Physical Drive tab, and select a drive which you want to replace.
3. Select Actions > Replace Drive.
   The Replace Drive dialog appears.
4. Select a replacement drive, and click Replace Physical Drive.
   A confirmation message appears.
5. Select Confirm and click Yes, Replace Drive to proceed with the replace operation.
   The drive is replaced and the data is copied to the selected component.
