I want to delete the annual account of 20 10, but because I changed the name of the account set and forgot to back it up, I only have the backup file of 2009, but after the annual account is established, it will become 20 1 1.
Digital speaking: 75% misoperation leads to data loss.
Hurriedly deleting useful documents without careful consideration or misoperation, such human errors or software and hardware problems, as well as system problems, sometimes lead to the loss of important materials. The "2006 Annual Data Repair Report" released by the Information Security Research and Service Center of the National Information Center in the first half of the year shows that from the data repair situation in China in 2006, hardware failures accounted for a considerable proportion, 80% of which were hard disk failures, which was related to the bottleneck stage of storage media. The large capacity, small size and high speed of hard disk all affect the quality of hard disk. In software failures, 75% are caused by user's misoperation. Although the success rate of software fault data recovery is as high as 98%, the disaster of data loss can actually be avoided if users pay attention to operating procedures during use.
A regular thing is that most of these security risks exist in PCs and notebooks. The server has strict requirements for data security backup and is maintained by professionals, so the frequency of data disasters is relatively low. Because PC and notebook are basic office tools, users' awareness of data security and backup has not been fully established, resulting in a relatively high proportion of data loss.
97% of multiple data failures can successfully recover data.
Forced shutdown and source disk operation will further aggravate data loss. According to the report, 7% of the people turned on and off the machine repeatedly after the problem occurred, resulting in 28% of the data of these people being unrecoverable. At the same time, 42% people did nothing after the problem occurred, and the success rate of data recovery reached 97%.
For computer users, deleting a file in Windows environment, even if the "recycle bin" is emptied, actually only deletes the directory information from the computer. As long as you don't format the hard disk or store new files on it, the data of the files that were deleted will actually remain on your disk.
The right medicine: you can use tools and software to rescue in time.
From a technical point of view, download appropriate tools, such as easy recovery, floppy disk Zip rescue, intelligent NTFS recovery, Recuva, power data recovery, etc. , you can recover files that were deleted by mistake. Even in extreme cases, even if some deleted files are partially destroyed, some tools and software can be used to restore some of their contents.
Need to remind everyone that some softwares can completely recover files of any format that have been deleted by mistake, and some softwares are special tools for recovering different types of files, such as compressed files, USB flash drives, video data, audio data and picture files. Therefore, in use, you should carefully choose the appropriate drugs.
In addition, some technical experts suggest that you copy the hard disk first, turn off the computer, then remove the hard disk before data recovery. Install the spare hard disk on the computer, and then install the Windows operating system.
When running Windows on the spare hard disk, you can install the data recovery tool software. After the installation, turn off the computer, and then install the newly removed hard disk on the computer, and install another blank hard disk with the same size. Start the system and copy a sector from the hard disk containing deleted data to a blank hard disk. After the copy is completed, turn off the computer and then remove the hard disk containing the original copy of the deleted data, and you can continue the data recovery process.
However, this method is more complicated, so it is best to ask experts for help, especially users who can't install Windows. Don't try it easily.
Key tips
1. Read the computer prompt before operation.
Some computer users don't like to read the tips carefully, and the "dialog box" is just a quick click. Problems are prone to occur at this time. You may have deleted files or documents that you shouldn't have deleted. So when you delete a file, be sure to read the prompt. In addition, before emptying the recycle bin, make sure it is a useless file again. When there are too many files in the recycle bin to be confirmed, select the "Restore" function to "restore" potentially useful files to the hard disk, and then delete them after determining that they are unnecessary.
2. Don't name the file at will.
Many computer users have been naming files at will for a long time, and you may forget the name of an important file, laying the groundwork for deleting files by mistake in the future. So when naming a file, please try to name it according to the actual content of the file. For frequently revised documents, it is best to indicate the revised draft or version after each revision. In this way, even if the files are sorted in the future, important files will not be deleted by mistake. In addition, you should know which disk and directory the important files are stored in to avoid being deleted by mistake.
3. Backup is very important
For files with small capacity, it is recommended that you back them up on a local disk. It is best to back it up to a disk in a different partition. For example, back up the files on disk D to disk E, so that even if disk D is formatted later or the whole disk fails, the files you need can be found on other disks. In addition, for large-capacity files, such as movies, you can burn them to CD-ROM, or store them on large-capacity USB flash drives and mobile hard disks, and keep a backup.
4. Don't save the new file before recovery.
At present, software repair technology is not as difficult as hardware repair technology, as long as the data is not overwritten, it can basically be successfully restored. However, there is a problem that needs your attention at this time, that is, remember not to store new files on the same hard disk before the files are restored. Because of the new file you saved, it is very likely that the file to be restored will be overwritten, resulting in the original file being unrecoverable.
Practical question and answer
1. Make full use of system recovery function.
Q: I deleted a system file by mistake, which caused the computer to run abnormally. Is there any way to fix it?
Answer: If this system file is only deleted to the recycle bin, it can be restored in the recycle bin. If it has been completely deleted, you can restore it through System Restore. At this time, you only need to click Start → Programs → Accessories → System Tools → System Restore, and then choose to restore my computer to an earlier time according to the prompts. Please note that the restore point time you choose must be the time before you delete the system file. Then restart the computer according to the system prompt.
2.Word, please set automatic saving.
Q: If you shut down because of power failure, and there is no saved Word document content, how can you recover it?
A: In the popular Word 2003, when you open Word again after power failure, the system will automatically prompt you to find unsaved files. After opening, select Save. In addition, I would like to remind you that it is best to set the auto-save function in the "Tools → Options → Save" menu of Word, and it is best to set the time interval of system auto-save to the shortest 1 minute, so that basically the problem of file content loss will not be encountered again, and because it is auto-save, the system will not pop up prompts frequently.
