This tutorial analyzes why the data on the deleted partition is recoverable and demonstrates the method of how to recover data from deleted partition easily.

Overview on the issue about deleted partition recovery

As we all know, partitioning a hard disk is required before the hard disk is used to store data. In order to better manage the hard disk, we can divide it into one or more partitions. However, once a partition is lost or accidentally deleted, the data on that partition may also be lost. So, If the partition is lost, is it recoverable? Is it possible to recover data from a lost partition? Is there any suggestion about how to recover data from the deleted partition in Windows 10/8/7?

Why the data on the deleted partition is recoverable?

Many users may be puzzled about why the data on the deleted partition is recoverable. In fact, if a partition is deleted, the system will remove partition information from partition table instead of completely wiping the disk area once occupied the deleted volume. The disk space becomes unallocated only without being wiped, which means partition recovery is possible. If the partition table and boot sector of the disk are not deleted, you can recover data from the deleted partition through Windows built-in tool or a third party data recovery software.
