How to recover NTFS partition without losing data

"I lost the D-partition in My Computer. I went to Disk Management and found it available as free space. So I tried to make it NTFS, but I had to format the drive and I don't want to, since it will erase my data. Does anyone know how I can restore my partition without losing my data?" -- from superuser.com

You save a lot of important information from your career, education, and social life on a computer and portable devices as everything becomes digital. If you don't have the most recent data backup, for Windows users, losing an entire NTFS partition or all of the NTFS partitions on a drive might cause significant data loss.

This article will introduce 4 ways for NTFS partition recovery and tell you how to recover an NTFS partition without losing data.

Can I recover from deleted or lost NTFS partitions?

Yes, lost data from a deleted or lost NTFS partition can be recovered through whole NTFS partition restoration or reliable data recovery software. However, the success rate of data recovery varies depending on how long ago the partition was lost and how the drive has been used afterward.

Common causes of missing Partitions

Knowing the common reasons behind the lost NTFS partitions, you will be able to avoid partition damage in the future.

  • Human error. When you attempted to clear a particular partition, you inadvertently or incorrectly cleaned the entire disk.
  • Corrupted partition table. The most likely causes of a corrupted partition table include viruses, sudden power outages, and bad sectors. Partitions may be lost as a result of the broken partition table.
  • Repartition or merge partitions. All current partitions will be destroyed if you repartition a hard drive or merge partitions into a single larger partition.

If you have overwritten your partition with new data, the chance of successful data recovery from a deleted NTFS partition will be very slim.

You should quit using the drive containing the lost NTFS partition and perform recovery as soon as you realize your NTFS partition has disappeared. Various methods prove to be quite effective in recovering lost NTFS partitions. Follow them one by one to recover your NTFS partition without data loss.

#3 Recover lost NTFS partitions by assigning a partition label in DiskPart

Another reason why your NTFS partition is invisible could be that Windows failed to give it a partition label. Hence Windows can't locate the NTFS partition for accessing the data. You can attempt to fix the NTFS partition that isn't showing up in Windows by manually assigning it a letter in the Command Prompt.

Here is how to do it via DiskPart:

  1. Press the Windows key to open the search box and search for cmd.
  2. Right-click on the Command Prompt and select Run as administrator.
  3. Type the diskpart command in the window and press Enter key to run.
    Run cmd as a administrator
  4. Run list disk to list all detected hard disks. 
  5.  Run select disk 1 to select the disk that contained the deleted or lost NTFS partition. Replacing 1 with your disk number. 
  6. Type list volume to list all volumes and press Enter to run it. 
  7. Run select volume 3 to select the volume that represents your missing NTFS partition without a label. Replace the volume number 3 of your own. 
  8. Run assign letter=d to assign a new label (letter) to the lost NTFS partition. Replace the letter d with any letter available. 
    cmd assign letter

You can now exit the Command Prompt and check in Disk Management to see if you have recovered NTFS partitions.

You did it! Share your joy with your followers.
