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 Synology 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 can RAID (Redundant Array of Independent Disks) configurations impact data loss in NAS Synology Diskstation DS114 devices?

RAID configurations in NAS Synology Diskstation DS114 devices can have a significant impact on data loss. Here are a few ways in which RAID configurations can affect data loss in these devices:

  1. Data Redundancy: RAID configurations like RAID 1 (mirroring) or RAID 5 (striping with parity) provide data redundancy by distributing data across multiple disks. This redundancy ensures that even if one disk fails, the data can be recovered from the remaining disks. It reduces the risk of data loss due to disk failure.
  2. Fault Tolerance: RAID configurations with redundancy also offer fault tolerance. In case of a disk failure, the NAS device can continue to operate without any data loss or downtime. The failed disk can be replaced, and the data can be rebuilt onto the new disk automatically.
  3. Hot Swapping: Many NAS devices, including Synology Diskstation DS114, support hot swapping of disks. This means you can replace a failed disk while the system is running without shutting it down. Hot swapping reduces the risk of data loss and minimizes the downtime required for disk replacement.
  4. Data Recovery: In the event of a disk failure, NAS devices with RAID configurations often have built-in data recovery mechanisms. These mechanisms can automatically rebuild the lost data onto a new disk using the redundancy information stored on the remaining disks. This simplifies the data recovery process and reduces the chances of permanent data loss.
  5. RAID Expansion: Some RAID configurations allow for easy expansion of storage capacity by adding more disks to the array. This expansion can be done without losing any existing data. It provides scalability and flexibility, reducing the risk of data loss due to insufficient storage space.

However, it's important to note that RAID configurations are not foolproof and cannot protect against all types of data loss. They primarily address disk failures and provide some level of data redundancy. Other factors like accidental file deletion, file corruption, or multiple disk failures can still lead to data loss. Therefore, it's recommended to have additional backup measures in place, such as regular backups to external devices or cloud storage, to further mitigate the risk of data loss.

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

Although NAS Diskstation DS114 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.
