In this comprehensive guide, we will explore various methods to help you learn how to recover data from lost partitions in Windows devices. Just go with these recovery workarounds one by one to restore data from lost partition easily.

What Causes Partition Loss on Windows Devices?

There are several reasons, ranging from human errors to technical issues, that contribute to the loss or deletion of partitions on Windows devices. It is important to understand the exact cause so you can apply adequate partition recovery methods and preventive measures to avoid such issues in the future.

Here are some of the main reasons for partition loss on Windows:

• Accidental Deletion: One of the main reasons for partition loss is accidental deletion. You may have inadvertently deleted the partition while managing or resizing the storage space using disk management tools. Such action deletes the partition and all the data stored within it.
• Formatting Errors: When you format any partition, all data on that particular partition will get deleted. It is important to create a backup of important files before you proceed with formatting the drive.
• Corrupted Partition Table: The partition table is a critical data structure that stores information about the partitions on a storage device. If the partition table becomes corrupted due to software bugs, hardware issues, or sudden power failure, it can cause a loss of partition information.
• Virus and Malware Attacks: Malicious programs like viruses and malware can infect the file system and cause damage to the partitions on a Windows device. Some programs can corrupt or even delete partition data, making it inaccessible or leading to complete partition loss.
