RAID 5 Data Recovery
The problems with your data are always spontaneous. Regardless of how well you prepared for blackouts, or virus attacks, when data loss happens, you will probably need some help. Your very first question will probably be:
How to recover RAID 5 disk failure?
First of all, calm down and realize that there is recovery software available that is able to save as much of your data as possible. If you are calm and ready to take the next steps, go to the next sections of this article, where you will be provided with proper instructions on how to recover RAID 5.
The first thing you need to determine before RAID 5 data recovery is RAID 5 array configuration.
It usually consists of the following parameters:
- The quantity of disks your RAID 5 contains. The minimal number for RAID 5 is three.
- The disk sequence and the block size used within an array.
- The stripe size used in your RAID 5.
This scheme is an example of basic RAID 5 containing three disks. The basic understanding of your RAID will be helpful before you start finding out how to recover RAID 5 data.
But if you don’t understand anything in tech, don’t worry. Diskinternals RAID recovery™ determines the configuration of an array automatically, and it takes a couple of minutes if proceed in the Reader/Uneraser mode. The next paragraph will be dedicated to an automatic way of RAID 5 disk failure recovery.
Recover Data from RAID 5 with software
The main thing to do to prevent data loss is backing up your data on a regular basis. Otherwise the possibility of restoring information correctly will be minimal. But anyway, you might try data recovery if you would like to save your data at least partly.
If you have encountered problems with RAID 5 data recovery, you can restore data with RAID Recovery™ by DiskInternals. This software will be able to save information and transfer it to a new location.
Defining disk configuration and technical parameters, as well as the possibility of recovery, will be made automatically. All you need is to follow the step-by-step guide provided below just for you.
Data Recovery from RAID 5 with 2 Failed Drives
RAID 5 users frequently have troubles with data recovery, regardless on array size. You will need the most powerful RAID recovery software to perform data recovery from the RAID 5 array because of complicated mechanisms of data storage. The good news is that RAID Recovery™ by DiskInternals can perform RAID 5 data recovery.
Again, if you cannot even remember when your last backup was made, the possibility of recovering your information, and, moreover, the functions of the applications you had, will probably not be restored. But you can try saving data anyway.
RAID Recovery™ by DiskInternals will make everything possible to save the maximum amount of information from your RAID 5 array.
Manual for RAID 5 array recovery
If you have faced the problem of data loss, and you are not a tech specialist, you might need some assistance to restore your data. Below you can find some step-by-step guides that might help you to make the RAID 5 data recovery process easier and faster.
The first tip is using the Diskinternals RAID recovery™ software in the Reader/Uneraser mode, because otherwise, you will spend a lot of time on disk checking. This small tip will save you a couple of hours, regardless of your array volume.
RAID 5 Data Recovery Guide:
The second tip about RAID 5 recovery is, never try to restore data on each disk separately. If earlier disks used to work as an array, restoring information from the whole array will be the one and only technically correct decision that will work. If you try to restore data on each disk separately, you are going to have multiple problems.
But let’s move on to array recovery. Regarding on the type of data loss you experience, whether the reason is physical damage to the drives or software errors, the steps leading you through data recovery will be similar. Notice that you will need a new physical drive or drives with the same capacity as your old RAID 5 array to transfer recovered information.
Steps to recover data from RAID 5
The most basic things you need to do in order to recover RAID 5 data from one drive are:
- Pull the disks out from NAS.
- Connect them to the computer.
- Open the largest EXT partition in the Linux reader.
- If that didn't work, use Linux RAID 5 Recovery.
These steps will help you to save the information you had on the array and then safely transfer them to the new storage. But if the reason for failure is not disk damage or software corruption, this way will probably not work.
Steps to recover data from RAID 5 with 2 failed hard drives
Performing RAID 5 failure recovery in cases when two disks have failed is risky and complicated. Even with Diskinternals RAID recovery™ software, data recovery can be done only manually. For example, if one disk is impossible to restore and the data on the second one is corrupted, parts of the data that can be read can be recovered manually.
To recover RAID 5 with 2 failed drives, do the following steps.
- 1. Connect the array disks to your computer as independent local disks.
- 2. Launch the Diskinternals RAID recovery™ software.
- 3. To repair RAID 5, open and perform the RAID Wizard; the new RAID disk will be added to the disk list.
- 4. In Reader or Uneraser mode, open the logical disk, which is contained in the Hard Drives section of the disk list from the RAID disk.
- 5. Highlight the data and save it to some new place using the Saving Wizard.
The software is pretty simple and intuitive, so you will be able to recover data from RAID 5 with 2 failed drives if you have a basic understanding of your RAID. Your data will be restored to some new location after the process is completed.
Diskinternals RAID 5 data recovery software will help you overcome complications to recover RAID 5 array.
