Hard drive partition may get deleted due to human error, virus infection, etc. Here this MiniTool tutorial is intended to introduce the best data recovery software to help you recover data after deleting a partition.

Common Causes of Partition Loss

Disk partitions are used to store personal data, applications, or files required to run Windows systems. Usually, we divide a disk into multiple partitions to separate personal data from system data. This helps prevent the system partition from becoming full and causing the system to become slow or unusable, and it also facilitates disk management and backup.

However, during the daily use and management of disks, partitions may be deleted or lost under various situations. Here is a true example:

“Hi! I accidentally made a mistake and already deleted a wrong-selected partition with data on it through the Diskpart app on Win 10. I have a backup of course but some of the files are not included in the last backup. I would like to recover the partition. Is there a good and free app to do that kind of task? Or what do you prefer from these commercial apps to buy for home users? Such of app would be handy I think on most of our PCs...Cos we never know when such of accident can happen.”www.tenforums.com

Here are some common causes why internal/external/removable disk partitions get deleted:

  • Accidental deletion: Partition deletion due to human error is the most common cause of partition loss. You can delete disk volumes through multiple tools such as Disk Management, CMD, PowerShell, etc.
  • Partition table damage: If the partition table is damaged, the system will not be able to locate the partition from which it was booted, which may result in data corruption, data loss, or partition loss.
  • Bad sectors: If one or more sectors on the hard disk are physically damaged, data or partition loss may occur.
  • Power failure: If you encounter a power failure during disk operations, such as formatting, the partition may be damaged or deleted.
  • Virus infection: If your computer or hard drive is attacked by a virus, the disk volumes may get lost.

Regardless of the circumstances under which the partition is lost, as long as the lost partition contains important files, you should stop using the disk as soon as possible and recover files. This can effectively prevent the data on the deleted partition from being overwritten by new data. Overwritten data cannot be recovered by any data recovery tool.

Now, you can see how to recover data from a deleted partition.

Safely Remove External Hard Drives/Removable Drives

For external hard drives or removable drives, if you do not remove the disk correctly, it may result in data loss or partition corruption. To avoid this, you should use the “Safely Remove Hardware and Eject Media” option provided by the operating system before removing the disk.

Use Reliable Antivirus Software to Kill Viruses

Virus attack is an important factor leading to data loss and even system failure. Windows comes with a virus scanner, Windows Defender, to protect your computer from virus attacks. It is recommended to keep Windows Defender turned on.
