ID  
RAID level  
Status  
Disk block  
Stripe size  
Array cache status  
Disk cache status  

Use one of the following methods to view array details:

From the Overview tab

  1. Click on the Overview tab.
  2. Click on the More icon next to an array.
  3. Select Info.

From the Arrays menu

  1. In the sidebar, open the Arrays menu.
  2. Click on an array to highlight it.
  3. Click the Array details.

Create an array

You can create an array when two or more hard drives in the device are listed in the Available Disks menu in the sidebar. Two options are available when creating an array:

Quick

LaCie RAID Manager automatically creates an array based on the number of available disks. A single RAID 1 array is created if only two disks are available. If more disks are available, a single RAID 5 array is created. In addition, LaCie RAID Manager will automatically:

  • Enable disk cache for optimal performance
  • Perform a fast initialization of the array
Custom

You choose how the array is configured, including:

  • Hard drives to include in the array
  • RAID level
  • Array name
  • Spare drive
  • Disk cache setting
  • Stripe size
  • Initialization type

Create a quick array

To create a quick array:

  1. Click on the Overview tab.
  2. Click Create array.
  3. Select Quick and click the Next button.
  4. Review the summary and click the Finish button.

After creating an array, your operating system prompts you to initialize and format the array. Follow the prompts to format the array.

Create a custom array

To create a custom array:

  1. Click on the Overview tab.
  2. Click Create array.
  3. Select Custom and click the Next button.

Choose RAID level

  1. Select the hard disks to include in the array.
  2. Select a RAID level.
  3. Click the Next button.

Configure RAID

  1. Enter an Array name.
  2. Choose an Auto format setting. When enabled, LaCie RAID Manager will automatically format the hard drives after creating the array using the format that provides the best performance for your operating system (NTFS for Windows or HFS+ for macOS).
  3. Choose a Spare drive setting. When enabled, one of the disks will be a dedicated spare drive for the array. (default = disabled)
  4. Choose a Disk cache setting. Enabling disk cache optimizes performance but adds risk of data loss in the event of power loss or system errors. Disabling disk cache reduces the risk of data loss, but performance may be affected. (default = enabled)
  5. Select a Stripe size. Large stripe sizes are often used when copying large media files such as videos, high end graphics, and audio files. Small stripe sizes are typically used for small files such as text files, documents, and web resources.
  6. Choose an Initialization type:
None No effort to fix potential sector errors. Array is available immediately. Not recommended due to possibility of corrupt data.
Fast Minimum effort to fix potential sector errors. Array is available immediately. Not recommended due to possibility of corrupt data.
Background Fixes sector errors that can lead to corrupt data. A background initialization can run for multiple hours depending on the array’s capacity—however, since the process runs in the background, you can write new data to the array while the initialization is underway.
Foreground Fixes sector errors that can lead to corrupt data. Faster than background initialization, but you can’t write new data to the array while the initialization is underway.
For descriptions of custom array options, go to
Spare drive
Cache
Stripe size
Initialization type

After creating an array, your operating system prompts you to initialize and format the array. Follow the instructions from your operating system to complete the formatting.

 Note for multiple arrays on the LaCie 12big Thunderbolt 3—When creating multiple arrays, it’s recommended that you avoid using consecutive disks in the same array. Performance for an array that has consecutive disks can be negatively affected. For example, do not create an array with disks 1, 2, 3 and 4. Instead, create an array with disks 1, 3, 5 and 7. You can use disks 2, 4, 6, 8 and 10 for the next array.

Delete an array

Deleting an array deletes all of its data. The data cannot be recovered from the LaCie storage device once the array has been deleted.

 Warning—Always back up your data before deleting an array.

Use one of the following methods to delete an array:

From the Overview tab

  1. Click on the Overview tab.
  2. Click on the More icon next to an array.
  3. Select Delete.
  4. At the prompt, confirm that you want to delete the array. Follow any additional instructions specific to your device.

From the Arrays menu

  1. In the sidebar, open the Arrays menu.
  2. Click on an array to highlight it.
  3. Click the Manage button.
  4. Click Delete.
  5. At the prompt, confirm that you want to delete the array. Follow any additional instructions specific to your device.
 The deletion process may take up to several minutes to complete. Do not disconnect or power off the device while LaCie RAID Manager deletes the array. The Create array button on the Overview tab will not be enabled until the deletion process is complete.
 Deleting the array removes the formatting from your disks. Your operating system will prompt you to initialize the available disks. It’s recommended that you cancel or ignore these prompts.

Create a spare drive

LaCie RAID Manager has two options for assigning disks as spares:

Dedicated spare Dedicated spare drives are used exclusively for rebuilding a specific array.
Global spare Global spare drives can be used by any array. You can only create a global spare drive if you have two or more arrays.

Create a dedicated spare

At least one drive must not have an array assignment in order to create a spare drive.

Add an available disk to an existing array

You can add an available disk to an array as long as it’s not being initialized or upgraded.

  1. In the sidebar, open the Available Disks menu.
  2. Click on a disk to highlight it.
  3. Select Add to array.
  4. Click please choose and select an array from the menu.
  5. Click Apply.

You can use the array during the upgrade but performance is affected.

Initialize an array

When creating a custom array, you can choose from four initialization options: None, Fast, Background, and Foreground. See Create a custom array.

You can also initialize an array as a maintenance task. Only a background initialization is available for an existing array.

 Caution—Make certain to back up your files before performing an initialization on an existing array. Files on the array that predate the background initialization will be deleted. However, you can write new data during an initialization.

Run or schedule a background initialization

Use one of the following methods to run or schedule a background initialization:

From the Overview tab

  1. Click on the Overview tab.
  2. In the Status column, click on (Not initialized).
  3. At the prompt, click Initialize.

  3. Click on the Maintenance tab and select Background initialization.
  4. Choose one of the following:
    1. Click Run to start the background initialization immediately.
    2. Click Schedule to set up a scheduled initialization. Select a date and time and click Create.

Check the array using Consistency Check

A consistency check scans the array for sector errors that could lead to corrupt data. It identifies and reports bad sectors but does not repair them, since repairing the array might require changes to the data, resulting in limited data loss.

Your data is safe during a consistency check since it’s non-destructive. You can use the array during the consistency check, but other disk activities may be affected.

To run a scan that fixes bad sectors, see Repair an array using Consistency Check and Fix below.

  Important info—You can perform a consistency check on an array that has had a full (background or foreground) initialization. You can’t perform a consistency check on arrays with a fast initialization or no initialization.

A consistency check is not available when:

  • The RAID level is being upgraded.
  • Another disk activity is in progress.
  • The array is degraded, broken, or only partially optimized.

Run or schedule a consistency check

To initiate a consistency check:

  1. In the sidebar, open the Arrays menu.
  2. Click on an array to highlight it.
  3. Click on the Maintenance tab and select Consistency check.
  4. Choose one of the following:
    1. Click Run to start the consistency check immediately.
    2. Click Schedule to set up a scheduled consistency check. Select a date and time and click Create.

Repair an array using Consistency Check and Fix

A consistency check and fix scans the array for sector errors and repairs them. While this operation is generally safe, there is a risk that some or all of your data can be lost, since repairing sector errors requires making changes to the array.

 You can perform a consistency check on an array that has had a full (background or foreground) initialization. You can’t perform a consistency check on arrays with no initialization or only fast initialization.

A consistency check is not available when:

  • The RAID level is being upgraded.
  • Another disk activity is in progress.
  • The array is degraded, broken, or only partially optimized.

Run or schedule a consistency check and fix

To initiate a consistency check and fix:

  1. In the sidebar, open the Arrays menu.
