Yes, You Can Recover Data From Mirrored Volume Quickly Now

Part 1 – Files Missing on Mirrored Volume after Power Failure

"Hi, i was working on my accounts for my business last night when i had a power cut. When the power came back on 2 folders were missing from 2 locations. They were both holding the accounts files for February but the odd thing was they were in two different locations and i had finished working on them and had moved to doing the accounts for match. The files were on a mirrored volume which i thought would guarantee that nothing would be lost in the event of an error. I tried chkdsk which would not run until i rebooted. It seemed to find some of the missing files and folders while it was running but then said something about deleting them. When windows restarted i still could not find any of the missing files or folders. Can anyone help?"

Are you familiar with this? What will you do if it is you who lose important files saved on a mirrored volume? As far as we know, a lot of computer users have had the experience of losing data after power failure, but not many of them happen to lose data stored on mirrored volume. Today, we'll talk about how to recover data from mirrored volume.

Most people know that mirrored volume is one type of the dynamic disk volumes, but only a few of them know exactly what a mirrored volume is and how to create a mirrored volume independently. More importantly, when a file is deleted accidentally from a mirrored volume, can you recover your deleted file? Or after you formatted a mirrored volume, is it possible to recover data off a formatted drive?

By taking those factors into consideration, we decide to explain the methods for recovering mirrored volume in different cases carefully. You need to get a MiniTool Power Data Recovery immediately after data loss. Then, all you should do is carefully reading & following the steps we are going to introduce. After that, we'll tell you what a mirrored volume is, how to create a mirrored volume in Disk Management and the difference between mirrored volume and RAID 1 drive exactly.

Part 2 – Recover Data from Mirrored Volume

By taking a look at the name, you can find that mirrored volume refers to the volume which stores exactly the same content with another volume; it is used to achieve fault tolerance. That is to say, the mirrored volume can be served as an easy backup.

When disasters happen to you – you delete useful files from a mirrored volume & also lose those files in another mirrored volume or you find the mirrored volumes have been corrupted due to unknown reasons. What you will do? You must want to retrieve files from mirrored drive, right? Here, we'll show you how to deal with such situations with MiniTool Power Data Recovery. In both cases, we'll take Windows mirrored volume recovery as an example. (If you want to recover data from Mac, please resort to MiniTool Mac Data Recovery instead.)

Note: the scan will be finished in a few minutes if there are not so many files in the selected volume. Yet, the scan duration will be extended a lot if you have stored a large number of files there.

Step 3: when the scan is finished, the found files will be displayed in the following software interface orderly. Now, you should do the following things.

a). open the folders found by software to see files.
b). confirm the deleted files you need by looking at the "File Name", "Size", "Creation Date" and "Modified Date".
c). check the files to recover by adding a check mark in front of them and pressing "Save" button in the lower right corner.

Note:
  • You can also make use of the "Find" and "Filter" function to narrow your search range effectively.
  • Besides, if you discover that the total size of selected files is larger than 1GB, you'll receive a "File Saving Limit" prompt window. At this time, you may as well resort to "Export Scan Result" function to save the current scan result manually. Then, get a license to upgrade your software from free edition to break the free recovery limit and then choose to "Load manually saved scan result" in the drive selection interface which is shown in step 2.

When the selected files have been saved to your appointed place successfully, you'll see a prompt window in software. At this time, you can go to that place and check the recovered files to see whether you have got back all the files deleted accidentally from mirrored volume. If you're satisfied with the recovery, you can close the software and put an end to dynamic disk data recovery. If not, please repeat above process.

How to Create a Mirrored Volume in Disk Management

We'll take Windows 8 as an example in the following volume creation steps.

Step 1: open Disk Management in Windows 8 by using the way you prefer. And then please navigate to "Disk Management" under "Storage".

Step 2: you have 2 choices in this step. One is creating new mirrored volume by using unallocated space and the other is adding mirror to existing volume. Please see how to do:

  • Right-click on the unallocated space on which you want to create a mirrored volume -> choose "New Mirrored Volume" from the pop-up menu -> follow the New Mirrored Volume wizard to finish creation easily.

    Note: this process requires at least 2 disks. And after clicking "Finish", you'll receive a prompt saying that the target disks will be converted to dynamic disks if one or two of them are only basic before the creation.

  • Right-click on the target volume -> choose "Add Mirror" from the pop-up menu -> select one available disk and press "Add Mirror" button at the bottom part.

    Note: a prompt window will also appear at the end of above process to inform you that the selected disks will be converted to dynamic disks automatically. At this time, you should press "Yes" button in the prompt window to confirm your selection.

Break Mirrored Volume VS. Remove Mirror

What if you don't like mirrored volume anymore? How will you deal with the current mirrored volume? Will you choose to break mirrored volume or remove mirror in Disk Management? What're the differences between them? Now, let's focus on the differences between "Break Mirrored Volume" and "Remove Mirror".

Break Mirrored Volume: this action takes away a redundant mirror of a volume directly. One part of original mirrored volume will keep the original drive letter and the other part on another disk will be a drive with no drive letter. And the breaking action will not delete the data stored in original mirrored volume. You should notice that the data fault tolerance property will be gone with breaking.

Remove Mirror: the removing mirror action from a volume will remove/destroy the data from the selected mirror volume as well. But, the other mirror or mirrors will be left intact. Besides, after you removed a mirror, you'll find the space on the disk which is originally taken by the removed mirror becomes unallocated.

Mirrored Volume VS. RAID 1

A mirrored volume is only a partition on dynamic disk which is provided with fault tolerance. It can be configured in Windows Disk Management with ease.

However, the RAID 1 (RAID is the acronym of Redundant Array of Independent Disks) refers to two disks which share and replicate data to ensure continuous availability. The capacity of RAID 1 is only equal to the capacity of one disk, because the other one is just served as a data mirror. So RAID 1 is also known as disk mirroring.

If you happen to lose data on a RAID 1, you may as well use MiniTool Power Data Recovery to get back lost files since it is also a good RAID recovery tool which has helped lots of people get rid of RAID data loss trouble.

Part 4 – Sum Up

Mirrored volume is used widely during computing, so accidents like data loss happen to users now and then. In order to prevent users from feeling frustrating when come across mirrored volume data loss, we provide effective solutions for them to recover data from dynamic volume in time.

In the beginning of this post, we give a specific case to show file loss disaster on mirrored volume. Then, we explain the exact steps to recover data from mirrored volume. After that, we also tell you how to create a mirrored volume by using just Disk Management and distinguish break mirrored volume from remove mirror. At last, we compare mirrored volume with RAID 1 to help you have a better understanding of mirroring.
