Here, we strongly recommend Eassos DiskGenius to recover lost and deleted partitions. This recovery tool provides partition recovery feature which is able to search for lost partitions on specified area, and then restore lost partitions to partition table. Therefore, lost partition can be restored to the state when it got lost. Besides, you can use this tool under Windows, DOS or WinPE environment so that you can carry out partition recovery even Windows cannot boot normally.

Now we're going to present the recovery process step by step. In this example, we choose a disk whose partitions have been deleted and it is full of unallocated space.

Step 1   Launch Eassos DiskGenius and you can see the disk that loses partitions. Select the disk and click "Partition Recovery" button.

Step 2  Click "Start" button and DiskGenius starts searching for recoverable partitions. Searching process is read-only and does NOT write any data to disk.

Step 3  Reserve partition you want to restore and ignore wrong partition.

Once a partition is found, you'll be asked to choose "Reserve" or "Ignore". How to make the choice? You can preview files in the partition, as the program allows to preview photos, videos, audios and documents. Thus you can easily make sure whether it is the lost partition you want to recover.

Select "Reserve" button if the partition is correct, and choose "Ignore" if the partition is wrong or contains no data. Selecting "Reserve" here does not mean writing the partition to partition table, for the action is still read-only to hard drive.

In the picture below, DiskGenius discovers a 5GB partition with FAT32 file system, and we can see files and folders in this partition. It is just one of the deleted partitions we are trying to restore, and we should click "Reserve" here. Then partition searching continues.

Now another partition is found and it is 9.4 GB in EXT4 file system. Still we need to preview files to decide if it is the one we need restore. All files in this partition are correct, and we should click "Reserve", as well.

Step 4  Click "Save All" to save partition table, so that lost partitions can be restored.

Since all lost partitions have been found, we can save them to current partition table, after which they will be restored successfully. Saving partition table changes information in partition table, which does not affect data on the hard drive. If you save wrong partition to partition table, you can search for partitions once again and then save correct partitions.

Guide 2: How to recover files from formatted partition?

Partition formatting wipes data and frees up disk space so that you can store new data. In other words formatting is the process to erase or delete data. In most cases, formatting partition is done on purpose to free up disk space, fix partition errors or change file system, but formatting a wrong partition by accident also happens.

Can files be recovered from formatted partition?

Formatting causes data loss issue, but formatted partition is still recoverable as long as files are not overwritten. Why formatted data is recoverable? When a partition is formatted, only file information such as name in the root directory and file allocation table is deleted; all file data is not wiped, which can be overwritten by new data. Hence, we should not do any writing actions to the formatted partition in case of destroying recoverable data.

Note: Windows provides two methods to format partition: quick format and full format. Full format wipes all data sector by sector and lost files are not recoverable. Fortunately, in most cases, we format partition or disk via quick format, thus lost data can be recovered from formatted partition. What's more, data recovery software can do formatted partition recovery.

Have you ever encountered the situation that you are not able to access a partition and get certain error message? If you check the partition in Disk Management or partition manager software, the file system is displayed as RAW or unformatted. If that is the case, the partition is damaged or corrupted and what you should do is RAW / damaged partition recovery.

Symptoms of RAW and damaged partition

When partition turns to RAW or gets damaged, the drive cannot be opened and its file system in Disk Management is displayed as RAW. If you try to open damaged drive, you may see following error messages:

The drive in G:\ is not formatted. Do you want to format it now?

H:\ is not accessible. The file or directory is corrupted and unreadable

Location is not available. H:\ is not accessible. The parameter is incorrect.

You need to format the disk in drive F:\ before you can use it. Do you want to format it?

D:\ is not accessible. The volume does not contain a recognized file system. . Please make sure that all required file system drivers are loaded ant that the volume is not corrupted.

While running CHKDSK, you'll get the error message saying" The type of file system is RAW. CHKDSK is not available for RAW drives "

Please do not format the RW or damaged partition although it asks to do so and there is no need to be that anxious when such errors appear. Formatting is likely to destroy information which is of great importance to successful recovery. You can retrieve data from damaged partition easily all by yourself, and the follow part presents the recovery procedure step by step.

How to recover data from RAW or damaged partition?

Step 1  Launch DiskGenius from your computer and select the RAW or damaged partition in the software.

In many cases, you can see files in the RAW NTFS partition directly without any scanning or searching. If you can see files, then save them to a secure location. If not, try following steps.

Step 2  Click "Tools" and choose "Load Current Partition Intelligently" option, as follows:

Note: this feature is specifically designed for corrupt NTFS partition recovery and it is able to list files in damaged NTFS drive immediately. For example, when NTFS partition cannot be opened in File Explorer and prompts "The file or directory is corrupted and unreadable", you can use this feature to do NTFS recovery without scanning the partition.

Step 3  DiskGenius displays data with original directory structure quickly. Then you can check if files are complete and correct.

If the partition is badly damaged, files cannot be listed in this way, you'll have to scan the partition using "File Recovery" feature.

Step 4  Copy and recover data. Select files you want to restore and choose "Copy To", then you can specify a path to save recovered data.

Step 5  Check recovered files.

You can open target folder to view recovered files and check if all your files have been recovered successfully. If yes, you can format the damaged or RAW drive and then copy recovered file back to that drive.

Case 4: Encrypted partition recovery

Many users are fond of protecting their private data by encrypting the partition that contains sensitive files. Other users cannot access the partition without correct password or secret key. Partition encryption is a double-edged sword. It protects personal with guaranteed safety, but you'll lose your data if password is lost. What's more frustrating, if the encrypted is formatted, damaged or gets lost such as deleted by mistake, do you know how to restore lost encrypted partition?

Since files in encrypted partition are private and sensitive, it is not appropriate to ask others to recover data in case of data leakage. The best choice is recovering lost or deleted encrypted partition on your own using partition recovery software.
