  </select>

> Defines the type of partition layout to create when formatting hard drives 2TB in size and
> smaller **only**. (All devices larger then 2TB are always set up with GPT partition tables.)
>
> **MBR: unaligned** setting will create MBR-style partition table, where the single
> partition 1 will start in the **63rd sector** from the start of the disk.  This is the *traditional*
> setting for virtually all MBR-style partition tables.
>
> **MBR: 4K-aligned** setting will create an MBR-style partition table, where the single
> partition 1 will start in the **64th sector** from the start of the disk. Since the sector size is 512 bytes,
> this will *align* the start of partition 1 on a 4K-byte boundry.  This is required for proper
> support of so-called *Advanced Format* drives.
>
> Unless you have a specific requirement do not change this setting from the default **MBR: 4K-aligned**.

> Note: After changing from **No** to **Yes** you must reboot the server for the change to take effect.  Changing
> from **Yes* to **No** however, takes effect immediately.
