DISK DATA RECOVERY

Short for Universal Serial Bus, USB is widely seen and used in our life. Common USB data storage devices include USB flash drive, USB hard drive, USB memory stick, and so on. Almost every USB data storage device is greatly welcomed by users. Correspondingly, USB data recovery issue becomes quite important. What if users deleted valuable data from USB drive by accident? What if they formatted the drive due to wrong operation? Though the methods for corrupted USB file recovery may be different, all users who are suffering from USB data loss have a common desire: recover as many files from USB drive as possible.
 

Know USB Software Architecture

Before telling users the way to achieve USB data recovery with the wonderful free program – MiniTool Power Data Recovery, we’d like to talk about the software architecture of USB.
 
As the bottom layer, UHCD is used to manage and control the USB host controller, which is a programmable hardware interface. Besides, it is invisible for other parts of its system software.
 
As the intermediate layer, USBD is on top of UHCD; it provides driver-level interface to meet the requirements for the driver design of existing device. USBD provides data transmission infrastructure in the form of I/O request packets (IRPs). It consists of the demands of data transmitted through specific pipe. In addition, USBD enables an abstract of device to appear on the client, so as to realize convenient management. As part of the abstract, USBD has the default pipeline, through which users can access all USB devices for standard USB control. The default pipeline describes the logical channel of communication between a USBD and a USB device.
 
As the top layer, USB Client Software (also known as USB Device Driver or client driver) is Responsible for handling specific USB device driver. Client layer describes all software entries which have direct impact on device. After the device was detected by system, these clients will have a direct effect on peripheral hardware. This sharing feature put USB system software between the client and its equipment. Thus, client will deal with this device according to the device image formed here by USBD.
 

USB Data Recovery – Safer Is Better

Now, let’s see how to recover files from USB drive by using MiniTool Power Data Recovery.
 

 
Actually, this recovery process can be roughly divided into three steps: choose function -> scan the target drive -> select files to recover. Of course, different functions should be chosen in different data loss cases. We mean, why do you think there’re so many functions waiting to be selected? For example, if formatting was performed to a USB drive with valuable data saved in, users should choose “Damaged Partition Recovery” for corrupted USB file recovery.
