DSM 6.2 to 7.1.1

If your drive has a Not Initialized allocation status¹, it may indicate that:

• The drive contains no system partition. DSM is not installed on the drive.²
• The drive is not in use and has not been assigned to a storage pool.
• The system partition, DSM, and the storage pool on this drive have been removed because of a drive/hardware failure or human error.

Check the scenarios below and follow the instruction that matches your situation:

• The drive is brand new and has just been installed in Synology NAS.
  If the drive is brand new, you can proceed to use the drive directly. For example, add the drive to a storage pool or set it as a hot spare drive.
• The drive belongs to a storage pool from another Synology NAS.³
  If you want to access the data on that drive, insert all of the drives associated with that storage pool into your current Synology NAS and restart the system. You may also need to take additional steps (such as repairing the storage pool) to return the storage pool to a healthy and accessible status.
