While working as a systems administrator or data manager in an organization, you are likely to have a setup where the users’ files are stored on a network attached storage (NAS) drive that is further configured as RAID 0. Usually, everything works well, until a situation arrives when the data gets corrupted or deleted accidently. In such a scenario it becomes your responsibility to recover and restore the important records to ensure that the production of the company isn’t jeopardized.
That said, here you will learn how to recover your mission-critical data if it is no longer available on the RAID 0 drive. In one of the following sections, you will also learn how to recover corrupt or deleted data from a standalone hard drive that your PC has.
In case you are not aware, RAID stands for Redundant Array of Independent Disks which is sometimes also referred to as Redundant Array of Inexpensive Disks. As the name suggests, a RAID is a collection of physical disks (typically the SSDs or SCSI disks) that are configured to work as one logical drive. If you have NAS, the application that comes along with the hardware allows you to configure and access the RAID drives via a web interface.
When talking specifically about RAID 0, your data files are stripped and the slices are saved across all drives that are the members of RAID 0. Because all the drives simultaneously work during the data read and write process, the storing and accessing of the files is comparatively faster.
However, RAID 0 doesn’t offer any data redundancy and neither does it have any fault tolerance. In simple words, when you save files in a RAID 0, no data backup is created. Furthermore, because the data stripes are saved in different hard disks, even if one physical drive fails, the entire data is lost.
You will get to know if your RAID 0 has some issue when you are unable to access your files or save the new ones. You will also be notified about the problem when you will access the RAID configuration page on your web browser.
As mentioned earlier, all the physical disks in a RAID 0 configuration work as one large logical volume but without any backup. Therefore, if you lose your files or they somehow get corrupted in a RAID environment, there is no way you can restore them, and the only solution you are left with is data recovery using an efficient tool.
Because the physical attributes of the RAID setups are different from those of the individual disk volumes, you need a program that is specifically designed and developed for the data recovery from the RAIDs. One such tool that has been in the market for a while now is Stellar Data Recovery. The good news is, Stellar Data Recovery is free to download and use for Windows computers.
The step-by-step instructions on how to recover data from RAID 0 using Stellar Data Recovery on a Windows 10 PC are explained below:
Note: It is assumed that you are using a network attached storage (NAS) system for RAID 0.
Step 1: Connect the Physical Disks to a PC
Turn off the NAS device, and disconnect the physical disks from it. Now, depending on the type of hardware, use your preferred method to connect the RAID to a different computer running Windows 10, and wait while all the disks are detected by the operating system. Note: If the OS fails to recognize any of the disks, or the disk fails to function, you won’t be able to recover the data from the RAID whatsoever.
Step 2: Scan the RAID for Missing Files with Stellar Data Recovery
Download and install Stellar Data Recovery. Next, launch the program on your computer. On the main interface, check the RAID Recovery box present under the Other Locations section, and click Scan from the bottom-right corner. On the RAID Reconstruction box that appears next, go to the RAID 0 tab from the top, select the RAID disk under the Select Hard Drives to Reconstruct RAID window in the upper-left corner, and then click the button with the Greater-Than sign to add the hard drive to the right window.
Check the Don’t know start sector of drives box, and manually select the block/stripe size from the Select one or more probable start sectors list that gets enabled. Next, click Build RAID from the bottom-right corner, and wait while Stellar Data Recovery reconstructs the RAID. Once the process completes, select the RAID drive, and click Show Volume List from the bottom-right corner. On the next screen, click to select RAID 0 from the Physical Disk list, and click Scan.
Step 3: Recover the Missing Files
Once the scanning process is complete, check the box at the top in the left pane to select all the files that Stellar Data Recovery found and are recoverable. Alternatively, you can also select the important files individually by checking their corresponding boxes from the list in the lower-right section of the box. Click Recover to continue. On the next box that comes up, click Browse, select a location to save the recovered files to, and click Start Saving to begin the RAID 0 recovery process.
Although Wondershare Recoverit is an extremely robust software that can recover data from your corrupt or inconsistent disks, it would be good to take some precautionary steps to avoid the issue from arising in the first place. A couple of tips in this context are listed below:
Because Wondershare Recoverit is a multipurpose program, it is not limited to merely recovering the files from the RAID setups. In fact, the application is also helpful for home users where they can recover their lost files from the hard disk that their PC has.
If your home computer has lost some files, you can follow the instructions given below to recover them using Recoverit:
Step 1: Select the Culprit Volume
After launching Wondershare Recoverit, from under the Hard Disk Drives section, click to select the radio button representing the volume you want to recover the files from.
Step 2: Start the Scan
Click Start from the bottom-right corner of the interface, and when the next window appears, wait while Recoverit scans for and finds the recoverable files in the selected volume.
Step 3: Recover the Files
As explained earlier, select all or only the important files from the scan results list, click Recover from the bottom-right corner, select your preferred destination location on the next box (other than the one you are recovering the data from), and click Recover to start the data recovery process.
Although RAID 0 offers improved performance when it comes to data read and write, it doesn’t back up your files or has fault tolerance. This is a good reason to avoid using this configuration type, and picking RAID 1, RAID 5, or RAID 10 instead. Nevertheless, if you have a RAID 0 environment and you cannot upgrade it to an advanced one, using Wondershare Recoverit would be highly recommended to recover the information in case it gets lost or corrupted.
In addition to the above details and process, there are a few other questions that people usually ask before they start configuring RAID of any level in their office or home environment. A couple of such queries include:
