Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

3/22/19

Short push and RAID synchronization

Applying a short push during RAID synchronization spins down the hard drives. The RAID synchronization continues the next time you spin the hard drives up via a short push.

Long push

A long push is a manual depression on the button that lasts more than four seconds. When the product is operating, a long push will cut the power to LaCie 2big RAID, forcing it to shut down immediately. A long push is not recommended for general use as it may result in data loss.

Quiet operation and heat management

To reduce noise during operation, LaCie 2big RAID uses a Noctua® cooling fan to pull heat away from the internal components. In addition to being exceptionally quiet, the Noctua cooling fan is temperature controlled, which guarantees optimal heat management by adjusting the rotational speed for the environment. Additionally, the enclosure’s metal casing dissipates heat from the hard drives, keeping them safe and prolonging their life. Since LaCie’s unique design draws heat away from the internal hard drives, the external casing may be warm to the touch after extended use.

Position and stacking

Always make certain to place your LaCie 2big RAID on a flat, even surface that can support the heat output and airflow of a professional hard drive enclosure. For proper heat dissipation, 2big RAID is designed to stand upright. Do not place the enclosure on its side when it is powered on.

The device does not support stacking. Do not stack other drives, enclosures, or equipment on top of the enclosure.

The warranty for your 2big RAID will be voided if you:

Stack 2big RAID on another device. Stack other drives, enclosures, or equipment on top of 2big RAID.

Important—Always eject LaCie 2big RAID volumes from your computer before applying a short push.



Important—The wide exhaust chamber on the rear of LaCie 2big RAID allows for enhanced airflow. Make sure that it is not obstructed and that there is a natural airflow across the casing.

Manage RAID

RAID stands for redundant array of independent disks. RAID contains the word array, and the two terms are often used interchangably. An array is a combination of two or more physical disks that are presented to the operating system as a single volume.

Disks are combined into different RAID configurations known as RAID levels. The RAID level you choose depends on which storage attributes are most important to you:

Capacity The total amount of data you can store.

Performance The speed at which data is copied.

Protection The number of disks that can fail before data is lost.

Your LaCie 2big RAID can be configured as RAID 0 or RAID 1. Each RAID level has its own advantages:

RAID 0—Data is not duplicated on both hard drives in RAID 0. This results in faster transfers and more storage, since the full capacity of both drives can be used to store unique data. However, RAID 0 lacks a very important feature: data protection. If a hard drive fails, all data in the array is lost.

RAID 1—RAID 1 provides greater safety since data is duplicated on each disk in the array. If a single disk fails, the data remains available on the other disk. However, this comes at a cost—since the same data is written to each drive, copying data takes longer and overall storage capacity is reduced by 50%. RAID 1 is a good choice when safety is more important than speed or disk space.

To summarize, each RAID level has its own advantages:

RAID level Capacity Protection Speed Factory default

RAID 0 100% None Excellent Yes

RAID 1 50% Excellent Good No

RAID setup as part of a new Toolkit installation

You can quickly configure the initial RAID level and formatting for 2big RAID as part of a new Toolkit installation.

Toolkit will not launch the RAID setup wizard in the following circumstances:

Toolkit was previously installed on your computer—for example, for use with another Seagate or LaCie device. The RAID level and/or format for your device were changed from their factory settings.

Comprehensive RAID management

If you’ve made changes to your RAID configuration or Toolkit is already installed, you can manage RAID levels and formatting using LaCie RAID Manager, a comprehensive tool for all of your RAID-compatible devices.

Hard Drive Maintenance

Precautions

“Hot-swapping” means that you can remove and replace hard drives while the enclosure is powered on. During operation, the hard drives should remain in their slots for optimal air flow. Airflow and fan performance are regulated by temperature. Observe all conventional ESD precautions when handling hard drives.

Replacing a hard drive

If a failed hard drive is under warranty, make certain to contact LaCie support to receive a replacement disk.

It’s not necessary to power down the device to replace a single hard drive.

1. Locate the hard drive you want to replace and place your index finger on the small hole on the right side of its disk tray.

2. Gently pull your index finger away from the enclosure and maintain a firm grip as it unlocks the hard drive from the SATA connector. Once it is loose, hold the hard drive with both hands as you remove it from the slot.

272big RAID

3/22/19

3. If you are replacing a failed hard drive with a full disk tray, skip to Step 4. Continue here if you are replacing the hard drive using the same disk tray.

Using a Phillips head screwdriver, carefully unfasten all four screws from their four slots.

282big RAID

3/22/19

Gently slide the disk out of the tray.

Place the empty disk tray onto a flat work area with the handle on the bottom left. Many disks have a label on one side and the printed circuit board on the opposite side. With its label side facing up, gently place the hard disk within the disk tray. Ensure the SATA connector is on the left. The four screw slots should align with the disk’s four screw holes.

4. Using a Phillips head screwdriver, carefully fasten all four screws into their four slots. Do not force the screws into the slots. Forcing the screws too tight into the slots can make it difficult to remove them later and strip the screws’ teeth.

indicating that the RAID is synchronizing data. You can continue to use the LaCie 2big RAID storage but performance is reduced until the synchronization is complete.

LaCie 2big RAID enclosure: non-serviceable components

The components inside the chassis are NOT hot-swappable and are NOT serviceable at any location outside of LaCie-approved service centers. Removing the cover voids your product’s warranty. Additionally, removing, replacing or changing any part in the enclosure or, performing any action that involves the components in the enclosure, voids the product’s warranty. If you are experiencing hardware errors or failure, contact LaCie support for assistance.

Optional Formatting and Partitioning

LaCie 2big RAID is delivered formatted in exFAT for compatibility with both Windows and Mac computers. If you use 2big RAID with only one type of computer, you can optimize file copy performance by formatting the drive in the native file system for your operating system—NTFS for Windows or HFS+ for Macs. There are two ways you can optimize performance:

Toolkit Optimize Format your drive for optimal performance with just a few simple clicks.

Manual formatting Use Disk Management (Windows) or Disk Utility (Mac) to format your drive in non-

native formats.

About file system formats

NTFS—The native file system for Windows. macOS can read NTFS volumes but cannot natively write to them.

Mac OS Extended (HFS+)—The native hard drive file system for macOS. Windows cannot natively read or

write to HFS+ (journaled) volumes. This is the best format if you intend to use LaCie 2big RAID with Time Machine.

APFS (Apple File System)—An Apple file system optimized for solid state drives (SSDs) and flash-based storage systems. While you can format your hard disk drive (HDD) in APFS, performance may be degraded when files on the drive are routinely subjected to extensive editing (for example, large-scale image, video, audio, and music editing). Note the following restrictions:

You cannot use an APFS-formatted disk as your Time Machine backup drive. Format LaCie 2big RAID to HFS+ if you intend to use it with Time Machine. APFS is only supported on macOS 10.13 or later.

exFAT—Compatible with Mac and Windows. exFAT is not a journaled file system which means it can be more susceptible to data corruption when errors occur or the drive is not disconnected properly from the computer.

FAT32—Compatible with Mac and Windows. However, FAT32 is a legacy file system designed for low capacity hard drives and it is not recommended for modern hard drives or operating systems. A FAT32 partition can reach up to 32GB when formatted on a Windows PC.

How to choose the file system format

Use NTFS if:

…you connect the storage device to Windows computers, and you don’t need to allow a Mac to write to the disk.

Use HFS+ if:

…you connect the storage device to Mac computers, and you don’t need to allow a Windows computer to read or write to the disk. HFS+ is the only format compatible with Time Machine.

Use exFAT if:

…you need to allow both Mac and Windows computers to read and write to the disk.

You can use FAT32 if:

…you connect the storage device to older Windows and Mac computers. FAT32 is not recommended for modern operating systems and computers.

Frequently Asked Questions

For help setting up and using your LaCie hard drive, review the frequently asked questions below. For additional support resources, go to www.lacie.com/support/2big-raid.

All users

Problem: My file transfers are too slow

Q: Are both ends of the USB cable firmly attached?

A: Review troubleshooting tips for cable connections below:

Check both ends of the USB cable and make sure that they are fully seated in their respective ports. Try disconnecting the cable, waiting 10 seconds, and then reconnecting it. Try a different USB cable.

Q: Is the hard drive connected to a Hi-Speed USB 2.0 port on your computer or hub?

A: If your hard drive is connected to a Hi-Speed 2.0 port or hub, the inferior performance is normal. LaCie 2big RAID performance will improve when it is connected to a USB 3.1 port or a SuperSpeed USB 3.0 port. Otherwise, the device operates at slower USB transfer rates.

Q: Are there other USB devices connected to the same port or hub?

A: Disconnect other USB devices and see if the hard drive’s performance improves.

Problem: I have an older computer with USB 2.0 ports

Q: Will my hard drive’s USB 3.1 Gen 2 port work with my computer’s USB 2.0 port?

A: Yes, the cable end that plugs into the computer (USB Type A) is compatible with both USB 3.0 and USB 2.0. Make certain to use the included cable with the correct USB Type A connector. However, the transfer rates are much slower with USB 2.0.

Problem: I must use a USB hub for my USB devices

Q: Can I use my hard drive with a USB hub?

A: Yes, the hard drive can be connected to a USB hub. If you use a hub and encounter detection problems, slower than normal transfer rates, random disconnection from your computer or other unusual issues, try connecting the hard drive directly to the computer’s USB port.

Please note that USB 2.0 hubs limit your hard drive’s transfer rates to USB 2.0 speeds.

Problem: I’m receiving file transfer error messages

Q: Did you get an “Error -50” message while copying to a FAT32 volume?

A: When copying files or folders from a computer to a FAT32 volume, certain characters in the names cannot be copied. These characters include, but are not limited to: ? < > / \ :

Check your files and folders to ensure that these characters are not in the names.

If this is a recurring problem or you cannot find files with incompatible characters, consider reformatting the drive to NTFS (Windows users) or HFS+ (Mac users). See Optional Formatting and Partitioning.

Q: Did you get an error message telling you that the drive has been disconnected when coming out of sleep mode?

A: Ignore this message since the drive remounts on the desktop despite the pop-up. LaCie drives conserve power by spinning down when you set your computer to sleep mode. When the computer awakes from sleep mode, the drive may not have enough time to spin up, causing the pop-up to appear.

Mac

Problem: The hard drive icon does not appear on my desktop

Q: Is your Finder configured to hide hard drives on the desktop?

A: Go to Finder and then check Preferences > General tab > Show these items on the desktop. Confirm that Hard Disks is selected.

Q: Is your hard drive mounting in the operating system?

A: Open Disk Utility at Go > Utilities > Disk Utility. If the hard drive is listed in the left-hand column, check your Finder preferences to see why it is not displayed on the desktop (review the question above).

Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Q: Did you follow the correct installation steps for your operating system?

A: Review the installation steps in Getting Connected.

Windows

Problem: The hard drive icon doesn’t appear in Computer

Q: Is the hard drive listed in Device Manager?

A: All drives appear in at least one place in Device Manager.

Type Device Manager in Search to launch it. Look in the Disk Drives section and, if necessary, click the Plus (+) icon to view the full list of devices. If you’re uncertain that your drive is listed, safely unplug it and then reconnect it. The entry that changes is your LaCie hard drive.

Q: Is your hard drive listed next to an unusual icon?

A: Windows Device Manager usually provides information about failures with peripherals. While the Device Manager can assist with troubleshooting most problems, it may not display the exact cause or provide a precise solution.

An unusual icon next to the hard drive can reveal a problem. For example, instead of the normal icon based on the type of device, it has an exclamation point, question mark or an X. Right click this icon and then choose Properties. The General tab provides a potential reason why the device is not working as expected.
