Recover Hard Disk Data

During the use of computers, we often encounter unexpected things, such as software setup errors, system viruses, accidental deletion of files, and so on, which may lead to damage or loss of data on our computers. If God gives you a chance, do you know how to save these important data? Come and see the following. How is data lost? Unfortunately, data loss caused by incorrect formatting or deletion. In this case, as long as you do not write new data to the partition where the lost data is located, the data recovery software has a high success rate for data recovery and the recovery rate is close to 100%. However, if you first use a professional data deletion software to delete data and repeatedly Delete and overwrite the data, then the data is basically lost. Unfortunate 2: Data loss caused by viruses. Because there are too many ways to destroy the hard disk by viruses, and most of the damages cannot be easily restored using general software, so ...... When the virus destroys the hard disk, pray that the success rate of data recovery is only about 30%. Unfortunate 3: Partition Table loss/error. The drive letter suddenly disappears due to virus infection, the drive letter cannot be opened, or the partition table is lost due to human operations, such as partition, merge, conversion, expansion and contraction, and Partition Table loss due to sudden power failure during work. Generally, 100% of data loss caused by manual operations can be recovered. If you have backed up the partition table, the success rate of data recovery will be greatly improved (see What should I do if hard disk partition is broken?). Unfortunately, data is lost after the system is reinstalled or the "Ghost" is incorrect. This type of problem is generally because the source file has been overwritten by the written data, the recovery rate is not satisfactory, only about 30%. Unfortunate 5: data loss caused by power failure during operation. This type of data recovery depends on the situation. If the data is not saved and the program used does not have the automatic saving function, it is generally difficult to recover. Programs such as Office XP and later versions are generally automatically backed up and restored. What should I do if data is lost? One of the conditioned reflections: if you do not have data restoration software installed, do not perform other read/write operations on the hard disk after data is lost. Do not install or store any files or programs on the hard disk. Otherwise, they will overwrite the files to be restored, making it difficult to recover data and affecting the success rate of restoration. Note: When installing Windows, you should install the data recovery software and immediately restore the deleted file after it is deleted by mistake. In this way, you can recover the deleted file. Conditioned Reflex 2: If the lost data is in the system partition, immediately shut down the system, take the hard disk, and attach it to another computer as the second hard disk for restoration. If your data is very important, especially after formatting and writing data into it, it is best not to take the risk of repairing it yourself, or ask a professional data recovery company to recover it. Conditioned reflex 3: When repairing damaged data, you must back up the source file before repairing it. If the disk partition is incorrectly formatted or deleted by mistake, we recommend that you first use Ghost to clone the incorrectly formatted partition and accidentally delete the partition where the file is located, and back up the original disk partition status, so that data can be restored again in the future. Many data recovery software have their own characteristics, and the data recovery rate also varies. Here we will introduce some typical data recovery software for your needs.

Software name: EasyRecovery Professional Software size: 32164KB adaptive platform: Win9X/Me/NT/2000/XP: [url] http://www.mydown.com/mydown/soft/35/35389.html [/Url] Start EasyRecovery Professional, as shown in 1.

The hard disk starts to read (the time for reading is determined by the size of the formatted partition, and EasyRecovery takes nearly half an hour to scan the author's 40 Gb partition). After scanning and searching, you can find the file you want to restore, click "Next" and select the storage location of the file you want to restore (do not select the formatted partition for the storage location, and select another partition to avoid overwriting the source file ). Then, click "Next", and the software will automatically recover. After the recovery is complete, click the Done button in the pop-up dialog box to exit.
This method can also be used to fix the misoperations when using Ghost to clone a partition and overwrite the wrong partition. However, the success rate of the restoration is very low, and readers should be prepared. 2. to recover Data corruption caused by virus infection or abnormal shutdown, you can start EasyRecovery Professional and click the "Data Recovery → Deleted Recovery" option, as shown in figure 2, in the open data recovery dialog box, select the partition where the data is lost or accidentally deleted.
By default, EasyRecovery Professional performs a quick scan on the selected partition and uses an existing directory structure to find the deleted directories and files. If the file is badly damaged, select "Complete Scan" for a full Scan. After scanning, all you have to do is find your data and recover it as much as possible. This method can also be used to restore the data of the USB flash disk. 3. Fix the Office File and enable EasyRecovery Professional in OE mail, and click "File Repair", as shown in figure 3. Its content is quite rich, "Access Repair" for Mdb files, "Excel Repair" for XLS files, "PowerPoint Repair" for pptfiles, "Word Repair" for DOC files, and ZIP compressed files. Their usage is similar. Here, we will take the DOC File for repairing the Word as an example. Select "Word Repair" and click "Browse for File" in the pop-up dialog box to find the DOC File to be repaired. Click "Next" and wait a moment. EasyRecovery Professionaly will generate a recovery file named "fixed file filename _ BAK" in the directory where the damaged file is located. TIPS: Before you fix a file, remember to close the corresponding program. For example, to fix the XLS file, remember to close the Excel file. Remember to back up damaged files. If it still cannot be repaired, you can use another repair program, such as the professional Word file Repair Tool DocRepair.
