====== Hard Disk Expansion: Single-Disk and Unprotected Volumes ======

Review the information below before attempting to add hard disks to a single-disk or unprotected volume.

<note important>**Important info on NAS Backup:** It is recommended that all users back up data to DAS or another NAS as further protection against disk failure or secondary points of failure (e.g. hardware, network, etc.). See [[..:backup:start|]] for details.</note>

===== Removing Healthy Disks from an Unprotected Volume =====

An unprotected volume can be:
  * SimplyRAID single-disk
  * RAID 1 single-disk
  * JBOD
  * RAID 0

**Removing a healthy hard disk from an unprotected volume while the LaCie 5big NAS Pro is powered on will delete all of the volume's data**. While removing healthy disks is not recommended, you can avoid losing data by shutting down the LaCie NAS first. Return the hard drives to their proper bays before powering on the LaCie NAS. \\ 

Additionally, powering on the LaCie 5big NAS Pro with a missing disk in an unprotected volume will break its RAID and all data will be lost.

The screenshot above shows a single-disk volume configured for LaCie SimplyRAID (for instructions on how to change the name of the volume from the default to //SimplyRAID//, see [[..:dashboard:storage#volume-tools|Volume Tools]]). Follow the steps below to add one or more drives to your single-disk volume:
  - Insert a new hard drive into the next available drive slot in your LaCie 5big NAS Pro (see [[5big04-diskinstall|]] for instructions). Following the disk installation, the **Dashboard > Storage** page should display at least one //New// hard drive. \\ {{:products:nas-pro:screenshots:raid5big:ss_raid5big_71.jpg?500|}} \\ 
  - Choose **Manage**.
  - Select **Add drive** and choose **Next**. \\ {{:products:nas-pro:screenshots:raid5big:ss_raid5big_72.jpg?500|}} \\
