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 Overland Storage 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 hardware failure lead to data loss in NAS Overland Storage SnapServer 210 devices?

Hardware failure in NAS Overland Storage SnapServer 210 devices can lead to data loss in several ways:

Hard Drive Failure: The SnapServer 210 typically uses multiple hard drives in a RAID configuration to store data. If one or more of these drives fail, it can result in data loss. The failure could be due to mechanical issues, firmware corruption, or other factors.
Power Supply Failure: A malfunctioning power supply can cause sudden power outages or fluctuations, which may result in data corruption or loss. It can also damage the internal components of the SnapServer 210, including the hard drives.
Controller Failure: The controller in the SnapServer 210 manages the storage system and facilitates data access. If the controller fails, it can lead to data inaccessibility or corruption.
Fan Failure: The SnapServer 210 relies on fans to maintain optimal operating temperatures. If the fans fail, it can cause the device to overheat, potentially damaging the internal components and leading to data loss.
Network Interface Failure: The SnapServer 210 connects to the network through its network interface. If the interface fails, it can result in the device becoming inaccessible, leading to data loss.
Firmware or Software Corruption: Hardware failures can sometimes cause firmware or software corruption in the SnapServer 210. This corruption can lead to data loss or inaccessibility.

It is important to regularly back up data stored on NAS devices like the SnapServer 210 to minimize the risk of data loss in case of hardware failure.

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

Although NAS SnapServer 210 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.
