Quick Scan The Quick Scan option allows you to recover files on your Mac with all their metadata intact – including file names and locations. It is a good option if you have just deleted the file you are trying to recover.

Deep Scan A Deep Scan takes the longest to complete, but is the most thorough scan for your Mac and can find files that the other scanning methods can’t. Chances are some files may be corrupted.

Undelete protected data Undelete is your best option for Mac data recovery if you installed Disk Drill before you suffered data loss, and you had the Recovery Vault and/or Guaranteed Recovery features enabled.

Universal Partition Search This function allows you to recover partitions on HFS+, FAT and NTFS volumes from your Mac. It works on a disk level and treats the disk as a binary entity, quickly scanning the disk for signatures of known partition headers.

Allocate existing files Finder fails to read your data, but you are sure it's not lost? Disk Utility reports your drive as unformatted? Disk Drill will scan the partition and retrieve the existing data from your Mac bypassing system data reading methods.
