How Do I Initialize a Drive in Synology NAS?

Each of the drives of your Synology NAS will have different Allocation status depending on the state the drive is in.

The drive Allocation statuses are:

i) Initialized: When you install the DSM operating system on your Synology NAS, it creates a system partition in all the available drives installed on your NAS. A drive will have the allocation status Initialized if the DSM system partition is installed on the drive and the drive is not used by any storage pools.

ii) Not Initialized: If a drive does not have a DSM system partition, it will have the Not Initialized status. If you install a brand new drive on your NAS, it will have the Not Initialized status as well.

If a drive has any hardware problems, it will also have the Not Initialized status.

iii) Normal: If a drive has a DSM system partition and is used by a storage pool, the drive will have the Normal allocation status.

iv) System Partition Failed: If the DSM system partition of the drive is corrupted due to hardware failure or it can’t be accessed for some reason, the drive will have the System Partition Failed allocation status.

In this article, I am going to show you how to initialize newly installed drives of your Synology NAS. So, let’s get started.
