In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from d2 USB 3 Thunderbolt (LAC9000353 / LAC9000303 / LAC9000465 / LAC9000531).

How to Retrieve Accidentally Deleted NAS LaCie d2 USB 3 Thunderbolt (LAC9000353 / LAC9000303 / LAC9000465 / LAC9000531) Data

Recover data from damaged RAID arrays inaccessible from a computer.

Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like LaCie also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How frequently should data be backed up to prevent loss on NAS LaCie d2 USB 3 Thunderbolt (LAC9000353 / LAC9000303 / LAC9000465 / LAC9000531) devices?

The frequency of data backups on NAS LaCie d2 USB 3 Thunderbolt devices depends on several factors, including the importance of the data, the rate at which new data is generated, and the tolerance for potential data loss.

As a general guideline, it is recommended to back up critical data on a regular basis. This could be done daily, weekly, or monthly, depending on the volume and importance of the data. If the data is constantly changing or being updated, more frequent backups may be necessary to minimize the risk of data loss.

Additionally, it is advisable to follow the 3-2-1 backup rule, which suggests having at least three copies of your data, stored on two different types of media, with one copy stored off-site or in the cloud. This ensures redundancy and protection against various types of failures.

Ultimately, the frequency of backups should be determined based on the specific needs and requirements of the user or organization using the NAS device.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS d2 USB 3 Thunderbolt (LAC9000353 / LAC9000303 / LAC9000465 / LAC9000531) can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

  • How does the NAS LaCie d2 USB 3 Thunderbolt handle data storage and retrieval for database applications, and what are its performance capabilities in terms of speed and latency?

    The NAS LaCie d2 USB 3 Thunderbolt is primarily an external hard drive and not specifically designed for database applications. However, it can be used for data storage and retrieval in such applications.

    When used as a storage device for database applications, the NAS LaCie d2 USB 3 Thunderbolt provides a large capacity for storing data. It supports both USB 3.0 and Thunderbolt interfaces, allowing for fast data transfer rates between the drive and the connected computer.

    In terms of performance capabilities, the speed and latency of the NAS LaCie d2 USB 3 Thunderbolt depend on various factors such as the type of hard drive installed, the interface used (USB 3.0 or Thunderbolt), the computer's hardware, and the specific database application being used.

    With USB 3.0, the drive can achieve data transfer speeds of up to 5 Gbps, while Thunderbolt can provide even faster speeds, up to 10 Gbps or 20 Gbps depending on the Thunderbolt version. These high-speed interfaces allow for quick data retrieval and storage, which can be beneficial for database applications.

    However, it's important to note that the overall performance of a database application also depends on other factors such as the processing power of the computer, the efficiency of the database software, and the complexity of the queries being executed. The NAS LaCie d2 USB 3 Thunderbolt can provide fast data transfer speeds, but the overall performance of a database application may also be influenced by these other factors.

  • Can the NAS LaCie d2 USB 3 Thunderbolt be easily integrated with popular database management systems (DBMS) such as MySQL or PostgreSQL, and does it offer any specific optimizations or features for database workloads?

    The NAS LaCie d2 USB 3 Thunderbolt is primarily a storage device and does not offer specific optimizations or features for database workloads. It is designed to provide high-speed data transfer and storage capabilities.

    To integrate it with popular database management systems like MySQL or PostgreSQL, you would typically connect the NAS to a server or computer running the DBMS software and mount the NAS as a storage location. The DBMS can then utilize the NAS for storing and accessing database files.

    However, it's important to note that while the NAS can provide storage for the database files, the performance and optimizations for database workloads would depend on the server or computer running the DBMS software. Factors like CPU, memory, and disk I/O of the server/computer would have a more significant impact on the database performance.

    If you require specific optimizations or features for database workloads, it's recommended to focus on the server or computer running the DBMS software rather than the NAS itself.
