In this article, we will take you through a DIY systematic RAID recovery approach that you can apply to safely rebuild and recover data from a broken RAID 0, RAID 5, or RAID 6 set.
A damaged or broken RAID can be a result of human errors, hardware or software failure, malware infection, mechanical errors, power outage, failing drive, bad sectors, or abrupt system shutdown, etc.
When a Redundant Array of Independent Disks (RAID) array breaks or corrupts, the RAID volume becomes inaccessible, and the data is lost. But unlike normal drive, you can’t access or recover data from RAID hard drives independently. You need to reconstruct or rebuild the RAID configuration to get back lost data.
However, that’s easier said than done!
RAID is a complex data storage technology that uses multiple disks to create one logical volume. While building RAID, several parameters such as a number of disks, parity, block size, block order, disk offset, file system, etc. are defined. A user must document these RAID parameters while RAID array construction as they come handy when you need to rebuild and recover data from a broken RAID.
But today we have access to some of the most powerful RAID recovery tools such as Stellar Data Recovery Technician. The tool makes RAID 0, RAID 5, and RAID 6 recovery simple and easy—even if you don’t know or remember the RAID parameters.
Mentioned below are the steps that can help you recover your inaccessible and lost files by rebuilding a broken RAID 0, RAID 5, and RAID 6 set. Following are some instances where the steps will help you restore your critical files from a broken RAID:
After RAID is broken, failed, or turned inaccessible, do not perform any hit & trial method, especially if the data is critical. The longer you use a broken RAID, the harder (and sometimes impossible) it becomes to get back data.
At least keep the usage to a minimum.
Turn off or unplug the broken RAID set and carefully disconnect each hard drive from the RAID array. Place the drives somewhere safely.
After disconnecting drives from RAID 0, RAID 5, or RAID 6 array, connect each drive to a Windows PC. You can use SATA/IDE connectors or a SATA/IDE to USB 3.0 converter cable or enclosure—especially if you own a laptop or PC motherboard does not have enough SATA/IDE ports available.
Use a RAID recovery software such as Stellar Data Recovery Technician, which comes with a SMART disk monitoring utility. This utility helps you check the SMART disk status before recovery.
The step is most important, as you never know when a drive may fail due to some underlying problem, which might also be a reason for your broken RAID. Checking SMART status gives you a better and deeper insight about the drive. Also, if the drive is suitable for or can survive data recovery scan.
So begin by downloading, installing, and launching Stellar Data recovery Technician software. Then follow the instructions given below:
To clone the impending drive, you need a new or healthy hard drive of either the same or larger volume. For instance, if the failing hard drive size is 500GB, you need a drive with either 500 GB or more capacity.
PLEASE NOTE: In case you don’t know or remember the RAID parameters, select Don’t Know from the required parameter drop-downs and click ‘Build Raid’. The software intelligently rebuilds a few probable RAID constructions which you can choose to run a scan and get back lost data
Deep Scan thoroughly searches for lost files based on file-signatures and facilitates RAW data recovery by digging deep into the RAID drives. Therefore, it takes much more time than the ‘Quick Scan’ but gets back maximum recoverable data from the reconstructed RAID volume.
TIP: Save the scan information in your PC—weighs a few KBs. The scan information can be loaded later anytime to resume the recovery process. This saves you from scanning the RAID again. Just click on ‘Resume Recovery’ icon at the top and save the scan info at your desired location
NOTE: If the software is not activated, it will open a web page from where you can get the activation key. Once you get the activation key delivered on your register email, enter it and proceed with further steps.
Use a different external disk or internal disk with enough space to save recovered data. Alternatively, you can also save the scan information and recover data in stages—as per availability of time and storage space
So that’s how you rebuild a broken RAID set for data recovery and retrieve the lost data. For more info and help on RAID recovery, comment down below or get in touch with our data recovery experts.
RAID is a logical arrangement of multiple disks, thus, is prone to corruption, and may break due to various factors such as power failure, abrupt system shutdown, hardware failure, or human errors, etc.
At last, it all comes to data. After all, RAID is built to store and access data without worrying about data loss due to disk failure. Also, people often consider RAID as a backup. However, RAID can never be backups as they are equally prone to corruption while being used regularly.
Thus, it’s important to have a regular copy of data, which is stored on RAID so that files can be restored without affecting the workflow and business continuity. Nevertheless, a RAID recovery software such as the Stellar Data Recovery Technician makes getting back lost files from a broken, damaged, or corrupt RAID array easier and convenient.
The software is equipped with all essentials required for safer data recovery from a broken, corrupt, or formatted RAID 0, RAID 5, and RAID 6 arrays in Windows.
