Causes for the failure of RAID5
RAID is an acronym for Redundant Array of Independent Disks which means the disk can survive failure or malfunction of one of the member of the RAID 5 disk. If the failure of a RAID 5 partition affects only one member disk then it can easily get your partition data back, without having any interruptions in the whole array. But in case of multiple disk drive failures, there are no chances of retrieving the array data without an external aid.
Here are the general causes for a RAID 5 partition failure
A RAID 5 partition can fail due to any of the below mentioned reasons:
The symptoms one can notice if one of the member disks of RAID 5 array has failed are:
In all such situations, all one needs to do is to swap a failed disk with a new one and start RAID rebuild.
Since RAID 5 type arrangement is capable of surviving single member disk failure, for multiple hard disk failures it becomes impossible to recover contents that were stored on the damaged disks. However, you can try and recover data that is stored on the remaining normally functioning disks.
Data can be restored from RAID 5 disks in the following situations:
Recovering data from failed RAID 5 disks:
In the RAID 5 failures which include operator problems, device controller failures or RAID 5 software failures, only the data is lost but the member RAID disks are working normally. In such cases, it is possible to retrieve data from a failed RAID 5. In order to be able to do that, you should determine the RAID 5 array configuration specifications and then restore data from it by making use of a powerful and reliable partition recovery software such as Remo Recover.
Here are the inclusions of RAID 5 configuration:
Remo Recover is a renowned application for restoring data from failed RAID 5 disks effectively and reliably. By using this tool, you get the simple step by step instructions with their respective screen-snaps that will enable you easily retrieve data from failed RAID 5 disks without any technical help. Beside this, it even helps you to execute NAS data recovery from RAID 1 hard disk in order to recover missing data. Just download the software and install it on your computer to begin performing data recovery.
Step 1: Download and install the free version of Remo Recover program on your PC and open the program. Select “Recover Partitions” option from the main screen. Then, it shows all the logical and physical disks available in the system. Choose the RAID 5 disk and click "Scan" button

Step 2: Now the tool scans the RAID5 disk and locates all its partitions with their file systems. Choose the required RAID partition and click "Scan" button to start recovering your files

Step 3: Once it finishes the scanning and recovery process, it displays the recovered files in two views "Data View", and "File Type View"

Step 4: At the end of the successful recovery process, you can preview the recovered files by right clicking on the file and selecting Preview from the displayed options. as illustrated in figure 4.

Step 5: At last, if you are happy with the recovery results of the software, buy the complete version and save the recovered files at the location of your choice, as the demo version doesn't allow to save the files
