Resort to Data Recovery if Partition Recovery Fails

Most of the time, Partition Recovery feature works for you to recover deleted partition. But if the hard drive is already repartitioned and has some new data saved, Partition Recovery tool is very likely to fail, either showing you overlapped partition or cannot find the lost partition.

Simply put, this Data Recovery feature is similar to MiniTool Power Data Recovery. OR we can say, Partition Wizard just puts that tool inside. Whatever, it is good news that now you can have a second choice to recover lost partition files using the same disk partition manager.

Note: Never install Partition Wizard to the location where you want to recover lost files.

Step 1. Right-click the partition/unallocated space to be recovered and choose Data Recovery from the context menu. OR you can go ahead to select Data Recovery from the toolbar.

Step 2. In the pop-up data recovery window, choose the partition or unallocated space to have a deep scan.

Step 3. Depending on the hard drive performance and the file size, MiniTool Partition Wizard needs various time to finish the scanning. It is worth mentioning that this tool will show the found files during the scanning process. So, if you have already found the files you need in the tree structure, you can pause the scanning process and then start data recovery immediately.

Please make full use of the Preview function to pick out the text and image files you really need. And then put a check mark in front of such files and Press the Save button.

Reasons Behind Partition Loss

While we do have some ways to recover lost partitions or lost files, it is better to figure out the causes behind partition not found which could help us deduce the possibility for partition not found. In fact, the possible reasons can be one of the followings:

1. Mistaken Partition Deletion

Human errors, as we can see, are rated as the main cause for partition loss. Human mistakes are unpredictable and inevitable in some degrees, especially when you are using some tools that have no warning message before execution. Obviously, accidental deletion can result in partition deletion.

2. Improper Partition Resizing

Partition resizing is actually quite risky and is vulnerable to error. If something went wrong during this process, such as sudden operation interruption, the partition can get lost. Therefore, it is not recommended to resize partition if you do not have sufficient knowledge about this operation.

3. Partition Table Loss or Damage

Partition table displays each partition to users. Although it is really significant, it is also ease of is corruption. Once the table becomes corrupt or gets lost, partition loss happens, and you will be unable to read or write data on that drive.

4. Partition Gets Corrupt

A partition may get corrupt due to various reasons. For instance, there are a large number of bad sectors on the partition, or your PC is running on defective RAM, or there are virus or malware infections or hardware issues. If the corruption happens in the partition header, the infected partition may disappear.

5. File System Corruption

Like the above reason, if the file system gets corrupt due to virus and malware infection, the hard drive will not be able to function as normal. Under this circumstance, some partition may disappear unconsciously.

6. Unexpected Shutdown

Unexpected system shutdown happens due to abrupt power outages, abnormal BIOS upgrading or mistaken application installation. In this course, not only will the computer malfunction but also the internal hard drive will suffer. If the system shuts down while the partition is being read/write accessed, partition may get corruption, leading to partition not found.

7. Run CHKDSK after Disk Defragmentation

To improve hard drive performance, you may run disk defragmentation on a regular basis. This will make your files organized contiguously. Nevertheless, if you run CHKDSK on Windows-based computer when disk defragmentation completes, the hard drive structure is likely to get corrupt and then result in serious partition loss.
