Learning data structure knowledge would yield twice the result with half the effort when user wants to recover data. How is the data stored on hard disk? What's the working principle? What's the data structure on hard disk? All these are basics of data storage. Yet some may say they just need to know how to recover data rather than how the data is stored. However, Just like opening a door, user should first understand the door structure so as to perfectly open it. If one really knows little about data recovery, I would like to recommend a wizard-style data recovery software, MiniTool Power Data Recovery, which doesn't require professional data recovery knowledge.

The more one knows about data structure, the better the data recovery
Talking about data recovery, we have to mention data structure, file storage principle and even the boot process of operating system. For a new hard disk, user should first partition and format, then install operating system on it so as to be able to store data. Let's take the Windows operating system for example. A hard disk generally comprises MBR, DBR, FAT, DIR and DATA field, which are closely intertwined with data storage.
1. DPT on MBR describes the partition number, size and other information on hard disk.
2. BPB parameter on DBR records the starting sector, terminal sector, file storage format and FAT number of partition where data exist.
3. The location of data is not stored sequentially but dispersedly on sectors and the function of FAT is to accurately find location of every sector and read them.
4. Dir records the files starting unit and properties, locates the file location and make sure the file size in combination with FAT.
5. DATA field is the real area for storing data and takes up the vast majority of hard disk space.

Easily recover data with MiniTool Power Data Recovery
Employing MiniTool Power Data Recovery to recover data is the very shortcut and user could download this data recovery software at http://www.powerdatarecovery.com for free. Remember not to install it to partition suffering data loss.
Launch MiniTool Power Data Recovery to meet the following interface:



This is a demo on recovering data from damaged partition. Select "Damaged Partition Recovery" to activate next interface.



Select the damaged partition, then click "Open" to meet the following interface, or we need to click "Full Scan" to check partition files (this operation is demonstrated on other example at our website).



After clicking "Open", user would see the partition data and user could click "Advanced Filter" to help find needed files as quick as possible.



In the "Advanced Filter" window, user could find desired files by file name, extension, size, creation time and data, etc. After setting, click "OK".



Now check desired files and then click "Save Files".



Click "Browse…" to specify saving location, and then click "OK" to finish data recovery.
