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 Netgear 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 network issues impact the data stored on NAS Netgear ReadyNAS RN426 devices?

Network issues can have several impacts on the data stored on NAS Netgear ReadyNAS RN426 devices:

  1. Data corruption: Network issues such as packet loss, network congestion, or unstable connections can lead to data corruption. When data packets are lost or corrupted during transmission, it can result in incomplete or incorrect data being stored on the NAS device.
  2. Data loss: If there are severe network issues like frequent disconnections or network outages, it can lead to data loss. If the NAS device is unable to establish a stable connection with the network, it may not be able to save or retrieve data properly, potentially resulting in data loss.
  3. Slow data transfer: Network issues can cause slow data transfer speeds, which can impact the performance of the NAS device. Slow transfer speeds can make it time-consuming to upload or download data from the NAS device, affecting productivity and efficiency.
  4. Inaccessibility: Network issues can make the NAS device inaccessible over the network. If the network connection is not stable or if there are configuration issues, users may not be able to access the data stored on the NAS device, leading to downtime and potential loss of productivity.
  5. Backup and synchronization failures: Network issues can disrupt the backup and synchronization processes between multiple NAS devices or cloud storage services. If the network connection is not reliable, backups may fail or become inconsistent, potentially leading to data loss in case of system failures or disasters.

To mitigate these impacts, it is essential to ensure a stable and reliable network infrastructure, including using quality network equipment, maintaining proper network configurations, implementing redundancy measures, and regularly monitoring and troubleshooting network issues. Additionally, having proper data backup strategies and implementing RAID configurations on the NAS device can provide an additional layer of data protection.

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

Although NAS ReadyNAS RN426 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.
