How to recover data from the deleted partition? This post speaks the ways to recover lost partition data and why a professional approach is a viable option.

Partitions are the logical disk that enables users to divide the computer’s hard drive into different partitions. Further, it turns your system into a more secure environment. For instance, you may have at least two partitions of the hard drive – one for operating systems and the other for data so that in case if system crash, then your data is less likely to get affected.

What’s the Purpose of a Partition?

Your computer treats each partition as a single drive. Depending on the requirement you can create multiple partitions. Allocate one for system files and others to manage your data files such as pictures, audio, video,  and documents etc. Always store your files on a separate partition rather than storing them in separate folders within the single partition. In the case of the system failure, you need to install OS in the primary partition without formatting other partitions.

Another feature of partition is that it allows dual-booting, i.e., you can install multiple operating systems on the same hard drive.

The Most Common Reasons for Partition Loss

We cannot deny the significance of partitions as it increases our productivity and protects our data. However, if something unexpected happens to the partition’s index file, then you won’t be able to access the data on that partition. Sometimes, there are situations when we are unable to access the partition:


  • Computer virus intrusion: When the partition is infected by the virus, then the Operating System is unable to locate it. Further, we cannot locate the partition in Disk Management as well.
  • Damaged Master Boot Record: Master Boot Record contains information about the partition and includes a table that locates each partition, master boot code, and disk signature.
  • Partition is hidden/drive letter is missing: If a partition has not been allocated a drive letter, then it remains hidden from Operating System. Also, if the assigned drive letter is changed, then accessing it with the previous letter runs an error.

  • Partition becomes RAW: This is the case when the partition is not formatted with the file system.
  • Access is denied to the partition: This error indicates that you don’t have access to the partition. To have permission to access the content of the partition, you need its ownership.

  • Partition shows unallocated space: This is the error when the partition has data; still, it shows unallocated space.
  • File directory becomes corrupt and unreadable: This error occurs when the MFT (Master File Table) is damaged.

What to do to recover lost partitions?

Your prime concern is to recover lost partition data, but there are certain things that you should consider:

  • Do not perform further operations as the more you mess with the hard drive more are the chances of overwriting it, and less will be the chance of recovering data.
  • Don’t format the disk thinking that it may bring back things to normal again. Formatting the partition only reduces the probability of recovering lost partition data.
  • Abstain from hit and trial methods as they can make the matter worse (permanently deleting your files) if done inappropriately.

How can you recover lost partition data?

If you are unable to find the partition in Windows Explorer, then you can check Disk Management.

Go to Control Panel, then click on Administrative Tools, after that click on Computer Management and locate the partition.

If the partition is there without the drive letter, then it means only the drive letter is missing, and you can access the partition again by assigning the drive letter.

Disk Management - Partition Recovery

Run Chkdsk Command

Chkdsk checks and repairs error such as directory errors, cross-linked files, lost clusters, etc. To run Chkdsk, follow these steps:

  1. Search CMD in a windows search box and then Run Command Prompt as administrator
  2. In the cmd window, type ‘chkdsk E: /f where ‘E’ is the drive letter and ‘f’ fixes errors on the disk

Note – chkdsk is not useful in case of RAW Partition error.

Once the process is complete, chkdsk repairs errors; however, this command-line is not preferable when you want to recover lost partition data.
