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.

Can the use of specific data compression or deduplication techniques impact the performance and data integrity on NAS LaCie d2 Quadra Hard Disk (301542 / 301543 / 301549) devices?

The use of specific data compression or deduplication techniques can impact the performance and data integrity on NAS LaCie d2 Quadra Hard Disk devices.

Data compression techniques aim to reduce the size of files by encoding them in a more efficient manner. While compression can save storage space, it also requires additional processing power to compress and decompress the data. This can result in slower performance when accessing or transferring files on the NAS device.

Deduplication techniques, on the other hand, eliminate redundant data by storing only unique instances of data blocks. This can save storage space by reducing the amount of data that needs to be stored. However, deduplication also requires additional processing power to identify and eliminate duplicate data. This can impact the performance of the NAS device, especially during the deduplication process.

In terms of data integrity, both compression and deduplication techniques have the potential to introduce risks. Compression algorithms may introduce errors during the compression or decompression process, leading to data corruption. Deduplication techniques rely on data fingerprinting and hashing algorithms to identify duplicate data, and if these algorithms are not implemented correctly, it can result in data integrity issues.

It is important to carefully evaluate and test the specific compression or deduplication techniques before implementing them on a LaCie d2 Quadra Hard Disk NAS device to ensure they do not significantly impact performance or compromise data integrity.

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

Although NAS d2 Quadra Hard Disk (301542 / 301543 / 301549) 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:

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

Where are user’s files stored?

The LaCie d2 Quadra Hard Disk (301542 / 301543 / 301549) network-attached storage keeps LaCie NAS OS operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

  Recovering data from a physically damaged NAS device can be challenging and may require professional help. However, it is not guaranteed that data recovery will be possible in all cases. Here are a few steps you can try:
  Check the power supply and cables: Ensure that the power supply and cables are in working condition. Sometimes, the issue may be with the power supply rather than the device itself.
  Test the hard drive: If the power supply is working, try connecting the hard drive to another computer or NAS device to see if it is recognized. If it is not recognized, the chances of data recovery decrease.
  Seek professional help: If the above steps do not work, it is recommended to contact a professional data recovery service. They have specialized tools and expertise to recover data from physically damaged devices. However, keep in mind that this can be an expensive process.
  Remember, it is always advisable to have regular backups of important data to avoid such situations.
