To help you recover information in complex scenarios, Uneraser™ employs the highly sophisticated Comprehensive analysis mode. In addition, the Quick mode won’t be much use if you formatted the disk (or flash drive, or memory card) as the file system will be empty after formatting.
This mode is blazing fast, really, but it can miss certain data, especially if a file was deleted a long time ago.
In Quick mode, Hetman Uneraser will scan the data in the file system, returning the list of recently deleted files in a few brief moments. There are two approaches to the recovery: Quick and Comprehensive. In fact, it shares the recovery engine with the much more expensive, professional tool Partition Recovery™. Uneraser™ may look simple, but it features a highly sophisticated data recovery engine under the hood.
