Friends will often use the computer encountered due to the negligence or other reasons, some required data permanently deleted. However, these data can not be found elsewhere, it is difficult to re-do them. That encounter such problems in the how to do? Is it hard to do out of their own, or get the data so there is no, and paid so wasted energy and sweat on it? Not! In many cases, we can find out the data! Here, I tell you some ways.
Permanently delete the data in two ways: one, delete the data related to empty the Recycle Bin and clearing system information. 2 Under normal circumstances, we are talking about permanent deletion is the first. The first case, the data in not re-cover the time, basically be able to recover. I want to say is the first case, the data recovery.
WINDOWS system is the most commonly used system, here I introduce to you under the WINDOWS system to permanently delete data recovery methods. Up points from the storage address, a data storage mainly consists of two parts, one is the directory information to facilitate rapid system for all data management; one is the data itself. In the deletion of data under WINDOWS, only the directory area (FAT or MFT) has made some changes to the system default piece of data that no longer exists, the data stored in the local air out. In fact the data itself stored in the region did not have any change, which means the data is still needed to code all. Based on this principle, as long as the delete operation, the address of the data itself is not stored the new data to re-write the code, then the data can be re-find out! Any one single document, all have its own unique file format has its standard start code and end code, but also its size, based on these initial code, end code and size, we can limit the use of this document code area, this code is extracted from the area marked up inherent in a separate format, a data also successfully restored.
Above describes a data deletion and recovery of the basic principles and operations. The resumption of the operation that there are certain limitations, and must be complete in the data region itself circumstances, in order to restore the data, so we met accidentally deleted data, they must stop using the hard disk, or even not to start the hard disk, in particular, deleted data is located in the system area, it should immediately shut down because the system is running a temporary file is likely to hurt your lost data. In the case that they are not really understand them, do not do so indiscriminately operation, the third party to seek professional help.
