It's important to get back to the data on a Thecus NAS N4100Pro RAID. This detailed guide has everything you need! If you want to know how to get back data from a Thecus N4100Pro RAID, follow these step-by-step instructions and get help from a professional. Say goodbye to worries about losing data and hello to recoverable files!
Renowned network storage vendor Thecus offers a range of NAS systems suitable for use in both residential and commercial settings. Many Thecus systems employ RAID; for two-disk storage systems, RAID 0 and RAID 1 are used, and for big systems with three or more hard disks, RAID 5.
Like other systems of this kind, these devices are pretty reliable in avoiding data loss, although there are a few reasons why your files can disappear.

What causes the loss of NAS data?
Most data loss is caused by system files getting damaged. Power outages or voltage spikes can damage your network access system's hard drives and additional infrastructure. Hard drives can lose data when they break down mechanically, when files are deleted by mistake, or when the drive is restored. Firmware upgrades on machines are another common cause of data loss.
Files, directories, and data may be hard to recover from a broken device since NAS systems normally store data in a RAID manner. It happens because data is copied to each disk that makes up the RAID volume in chunks, which means that before you can access the data, the damaged RAID system must be rebuilt. Selecting the appropriate tool is essential to the success of your endeavor if you wish to recover the data on your own; however, if the data is not critical, this should be left to an expert.
What causes data loss on NAS devices?
One of the main reasons people lose data is that system files get damaged. Loss of power or sudden changes in voltage can damage hard drives, network area system controllers, and other hardware. Reformatting, accidentally deleting files, and problems with the hard drive can all cause data loss. Machine firmware updates are another common cause of data loss.
Retrieving files, directories, and data from a faulty device may be challenging because NAS systems normally store data in a RAID fashion. Data is copied to each disk that makes up the RAID volume in fragments, which causes the RAID system to break before you can access the data. This is why it happens. The success of your mission depends on the instrument you choose if you wish to recover the data on your own; however, if the data is not critical, this should be left to an expert.
The formation of a RAID
First, let's examine how to configure a RAID system on a network storage device from Thecus. Expand the "Storage" tab to choose the RAID settings after the NAS management tool has opened.
If you are creating an array for the first time, click "Create," and if you need to remove or edit an array that already exists, click "Edit." The array can be moved or enlarged, and there is a "Remove RAID" option underneath. It will erase all disk data if you click on it. Click "Yes," then confirm your choice by typing "Okay" in this field. Okay, the RAID has been successfully removed.
To begin creating a new array, click "Create." After choosing the disks you want to include in this array, a file system, and a RAID level, click the "Create" button below. You can also modify the strip size (which is 64 KB by default) and RAID ID if necessary. Click "Yes" and then "OK" to confirm your choice.
Create a shared folder.
When you select the shared folder configuration option after building the RAID system, you can change the access rights or create a new folder.
To create one, select the "Share Folder" option under the "Storage" tab and then click the "Add" button on the right side.
From the "Storage" menus, decide "Share Folder" to make a folder of your own.
Once you have secured the access circumstances, assign it a name. Kindly verify your intentions through choosing "Yes" and then clicking and "Apply". The process of setting up a shared folder has come a long way.
Configure the access settings and give it a name.
Steps for enabling an FTP server
Now we need to set up an FTP server.
Open the "System Network" tab, choose FTP from the list, and then click "Enable FTP Connection." To validate the changes, click "Apply" and "Yes" after selecting other parameters and checking the box next to "Enable." Your FTP server is now functioning.
Expand the "System Network" tab to allow FTP connections.
At this point, you can access the network drive using an FTP connection and write files to the shared folder.
iSCSI volume creation instructions
To create an iSCSI volume, select the "Storage" - "Space Allocation" - "iSCSI Target" tab.
To create an iSCSI volume, go to Storage -> Space Allocation -> iSCSI Target.
Click the "Add" button here, then "Enable," check the box next to it, alter the size, name, and other details, supply login credentials if necessary, and then click "Yes" and "OK" to finish.
Name, size, and more parameters should be supplied.
The iSCSI volume has now been created. The final step is to attach it to your computer and format it via Disk Management. After that, it should appear in Windows Explorer.
Getting data recovered from a malfunctioning NAS
If you format a hard drive, inadvertently delete files from a hard disk inside a NAS system, miss configure the disk array, or experience other data loss scenarios like losing access to the network drive, damaging the RAID volume, or experiencing other data loss, you need a specialist data recovery tool to recover your data.
Whereas most NAS devices are Linux-based systems with hard drives formatted for the Ext file system, RAID arrays are often built using mdadm or LVM technologies. Such disk arrays that are connected directly to a Windows PC become unreadable.
Using the reputable data recovery solution for NAS configurations, BLR NAS RAID Recovery Software, you can read the devices and extract any information from them. With most file systems, technologies, and RAID kinds supported, it can usually instantly rebuild the lost RAID.
To start getting the data off of the broken NAS, the disks should be taken out and connected to a Windows PC. Windows might tell you to format or "initialize" the drives so that you can use them after the system starts up. Remember that allowing either method can erase all remaining data, hence you should never agree to it.
It can be advised by Microsoft to format or initialize the drives.
The disks will be automatically identified, their service information retrieved, and the compromised RAID configuration rebuilt using BLR RAID Recovery Tool. Once you've picked a volume, you can look at the detailed information about the set below to make sure the program got it their freedom.
Get data off of unreachable corrupted RAID arrays on a PC.
Compromise RAID will be immediately rebuilt by BLR NAS RAID Recovery.
Make a right-click on the disc and choose "Open" to start looking for files. At this stage choose the scan type. Upon correct construction of the array, "fast scan" will be available.
Click "Next" to start looking through deleted files. To go to the search results once the process is complete, click "Finish."
As can be seen, the software found every file on the network drive and easily fixed the broken RAID. If you search for deleted files, you can discover them indicated by red crosses. The files without these crosses are those spread over the array drives.
Choose the data you want back, then click "Recovery." Click "Recovery," choose the location to store the files, and then click "Finish."
Having chosen the files you want to recover, click "Recovery."
The files you have selected will eventually be kept in the recovery folder you have specified.
Getting data out of an iSCSI drive
If you use an iSCSI disk and inadvertently delete some files from it, no disks need to be removed from the NAS system and placed on a PC.
BLR RAID Data Recovery Tool can easily inspect and recover accidentally deleted data because such a drive is identified as physical.
BLR RAID Recovery knows a network iSCSI disk to be a physical one.
To begin the recovery procedure, right-click the disk and choose "Open." Choose the type of scan (a "Fast scan" should work well most of the time), let it complete, and then check the outcomes. The application has recognized the erased files. Replacing them is the last stage.
How to repair a damaged array by hand using the RAID Constructor
Sometimes corrupted disks or lost service information lead BLR RAID Recovery to have problems automating the array reconstruction process. Manually reconstruct the RAID using the RAID Constructor if the NAS data recovery software was incapable of doing so with the available hard drives and you are aware of their properties.
To start, open the RAID Constructor and choose "Manual mode."
Use the arrows to show the order of the disks you want to add, then click the "plus" button to replace the missing disks with empty drives. Fill in the following box with all the RAID characteristics—size, block order, and type—that you are aware of. Additionally adjustable is the offset, which helps identify the start of the disk. Every now and then the software may have trouble identifying it automatically; in such instances, you will have to enter the offset amount by hand.
Enter the disk addition, block order, RAID type, and any other information you know.
Once you hit "Add" and have listed every property you know, the manually built array will appear in the Drive Manager.
Start the scan, then when you identify the files you want to recover, choose "Recovery."
