数据恢复与备份（Data recovery and backup）.doc

数据恢复与备份（Data recovery and backup） Rationale: advanced data formats such as formatting! It can be restored! Because the window system only changes its own record on the hard disk (so you can understand that the window system thinks Ive deleted it, but the data actually doesnt have to be deleted!) So it can be restored! Note: the biggest disadvantage of data recovery is that you cant recover low-level formatted hard disk data, or use data software to write each byte of the hard disk into the same characters! Its also conceivable that formatting is invalid for viruses, because they are still inside the hard disk! So it must be anti-virus! Operating procedures: 1: no more copy files, and also minimize the hard disk! Two: soft data recovery. To identify the hard disk, but the data lost, deleted, false cloning, software conflicts, virus damage, data recovery software, artificial restoration! Three: can not identify the hard disk, and no hard disk, the outer circuit board damage, chip breakdown, unstable voltage burned! Program: circuit board maintenance! Four: cannot distinguish the hard disk, and the hard disk has the unusual sound! Causes: physical track damage, internal circuit track breakdown, head damage! The inner circuit is repaired, and the disc cavity is repaired in the ultra clean room! Choose recovery software: generally easyrecovery software, which contains files, photos, U disk, etc., as well as advanced recovery! Deleted recovery after formatting, recovery! Recovery of the recycle bin after deletion! Note: be patient, and if you dont succeed, test multiple software or software a variety of methods! It is normal to find part of the data missing or part of the file not available! Software document recovery, note: 1, the partition will file inside the filter (*. *) to (*.doc) and a finaldata software is more convenient, common is the standard version of OEM file - Open - select the driver (and physical drive oh) Note: the missing folder is restored file!
