  • 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.
