1.3. Partition Damage

In the case of partition damage, the job for the undelete files software is to analyze the surface of the HDD and retrieve clues around structure of the logical data in order to reconstruct the partition or drive parameters (such as the first sector number, cluster size, file system type, etc.).

As this process makes logical connections based on probability, it creates an entity called a virtual drive. Without any kind of drive structure, no data can be retrieved. The virtual drive partition will give the user some data to work with.

This User Guide assumes that you have some basic knowledge of hard disk drive and file system organization to be able to understand the recovery terminology and examples.
