How to prevent partition loss in the future?

Partition deletion or loss is complicated and varies for different reasons. Partition deletion would happen when you delete one of the partitions accidentally or without your consciousness, for example, a virus or malware attack.  

Many people have no idea what happened to their hard drives and why their partitions were lost. If you haven't backed up the important files, the data may be lost forever.

Therefore, prevention is more important than problem-solving. It may be helpful to pay attention to the following tips in daily use.

  • Back up vital data. The most important is to back up data to another external hard drive. Alternatively, AOMEI Backupper could help you to back up files for various needs.
  • Double-check before delete. Before deleting files or partition, or even format partition or hard disk, it’s better to double-check the data stored in the partitions or hard disk.
  • Use anti-virus software. Regularly detect the hard disk with reliable anti-virus tools to protect the important data from being lost or deleted for no reason.
