In this article, we’ll find out how to recover data from RAID 1 and RAID 0 based on Qnap TS-219P+ network-attached storage, how to recover accidentally removed files from the recycle bin, what to do if this option is inactive, if there is no access to the disk array because of a NAS failure, or if the RAID is degraded.

This QNAP NAS model is designed to use two hard disks. To improve resilience and data safety, such devices enable you to create RAID systems of various types. However, even the most reliable storage systems may encounter emergencies like accidental deletion of files, formatting or damaging the hard disk, system errors, controller failures and other hardware issues, which may result in loss of important data.

This specific model supports two RAID types, RAID1 and RAID0, as well as JBOD, which is sometimes referred to as linear RAID, but technically it isn’t a RAID at all. In the end, redundancy in this NAS is only achieved by using a mirrored RAID. But if one of the disks fails in either RAID0 or JBOD, a part of the information is bound to be lost. In this article, we will explore a situation when the NAS is broken; all the files are still on its disks but it’s impossible to retrieve them unless you use a specialized software tool.

The matter is that a NAS storage device uses its own operating system which builds the RAID in a certain way and then writes data to its disks. Even when the hard disks are connected to another storage device or computer, their condition cannot be restored.

For example, when the disks are connected to a Windows computer, you will see some partitions with an unrecognized file system; another possible case is that the operating system will suggest initializing them in the Disk Management app – which is going to erase all the data still remaining on the disks. So in the end, you are going to lose access to the files or even lose the files forever.

In a Linux operating system, the disk partitions will be displayed as Linux RAID, and the option to mount is unavailable.

You should remember that if you choose to initialize the hard disks in Windows or modify the volume in Linux, this action can erase all the information, and it will make recovery very difficult. Never take any steps involving the hard disks unless you really know what you’re doing, since there is a risk of losing your data permanently.

To retrieve the information from the hard disks, you will need a special tool to rebuild the RAID system and restore access to the files which are stored inside the disk array.
