Enable auto start:

:   <select name="startArray" size="1">
    <?=mk_option($var['startArray'], "no", "No");?>
    <?=mk_option($var['startArray'], "yes", "Yes");?>
    </select>

    > If set to 'Yes' then if the device configuration is correct upon server start-up,
    > the array will be automatically Started and shares exported.<br>
    > If set to 'No' then you must Start the array yourself.

Default spin down delay:

:   <select name="spindownDelay" size="1">
    <?=mk_option($var['spindownDelay'], "0",  "Never");?>
    <?=mk_option($var['spindownDelay'], "15", "15 minutes");?>
    <?=mk_option($var['spindownDelay'], "30", "30 minutes");?>
    <?=mk_option($var['spindownDelay'], "45", "45 minutes");?>

    <?=mk_option($var['spindownDelay'], "2",  "2 hours");?>
    <?=mk_option($var['spindownDelay'], "3",  "3 hours");?>
    <?=mk_option($var['spindownDelay'], "4",  "4 hours");?>
    <?=mk_option($var['spindownDelay'], "5",  "5 hours");?>
    <?=mk_option($var['spindownDelay'], "6",  "6 hours");?>

    <?=mk_option($var['spindownDelay'], "8",  "8 hours");?>
    <?=mk_option($var['spindownDelay'], "9",  "9 hours");?>
    </select>

    > This setting defines the 'default' time-out for spinning hard drives down after a period
    > of no I/O activity.  You may override the default value for an individual disk on the Disk Settings
    > page for that disk.

Enable spinup groups:

:   <select name="spinupGroups" size="1">
    <?=mk_option($var['spinupGroups'], "no", "No");?>
    <?=mk_option($var['spinupGroups'], "yes", "Yes");?>
    </select>

    > If set to 'Yes' then the [Spinup Groups](/Help) feature is enabled.

Default partition format:

:   <select name="defaultFormat" size="1">
    <?=mk_option($var['defaultFormat'], "1", "MBR: unaligned");?>
    <?=mk_option($var['defaultFormat'], "2", "MBR: 4K-aligned");?>
    </select>

    > Defines the type of partition layout for unformatted hard drives 2TB in size and
    > smaller **only**. (All devices larger then 2TB are always set up with GPT partition tables.)

    > **MBR: 4K-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**.

Force NCQ disabled:

:   <select name="queueDepth" size="1">
    <?=mk_option($var['queueDepth'], "0", "No");?>
    <?=mk_option($var['queueDepth'], "1", "Yes");?>
    </select>

    > This is a system "tunable" parameter.

    > If set to 'Yes' then "Native Command Queuing" to array drives is disabled.<br>
    > If set to 'No' then it is enabled.  Most users find that overall system performance is better with
    > NCQ turned off.
