Generally speaking, the recovery software can recover the files that have just been deleted and have not done anything, which is basically 100% recovery, but your situation is to format it first, and then install the system, then you have carried out subsequent operations, then the possibility of recovery is much lower, after all, reinstalling the system may overwrite the location where the original data was stored, so there are the following suggestions.

First, if the data is really important, then spend money to hire a professional data recovery lady to recover, before the data recovery, do not do anything on the computer to prevent overwriting the data.

Second, if it is not very important, then you find a data recovery tool to try to recover, and put the recovered data in other drive letters, and the data recovery software you install should not be installed in the system disk. Fit other plates and you're good to go.

Tool required: AuroraDataRecovery. The steps are as follows:

2. After the software is running, directly double-click the E disk that needs to recover data.

3. After the program finds out the data, it will be put into the directory with the disk E disk to be recovered, and check all the data that need to be recovered.

4. Then click Save File, and the program will re-call the selected file to make it.

If you overwrite your system and overwrite important files and don't back them up, it can lead to permanent loss of files. However, if you quickly realize the problem, here are a few methods that may help recover your files:1

Use Data Recovery Software: There are some data recovery software that can scan your hard drive to find deleted or overwritten files and try to recover them. For example, Recuva, Easeus Data Recovery, etc. are some of the more well-known data recovery software.

2.Restore System Backup: If you created a system backup before the system overwrite, you can try to recover the lost files from the backup.

3.Try to restore the system state before the overwrite: If you made a system backup of your computer and the backup file contains a version of the overwritten file, you can try to restore the system state before the overwrite.

However, these methods do not guarantee a successful recovery of your files. Therefore, in order to avoid losing important files, we recommend that you back up your data regularly to prevent the unavoidable.

If you also work in the IT industry, then you should know that after the data is overwritten, it is basically impossible to recover. However, the data you covered to the E disk is just a ghost system, not all of which have been covered by the E disk, so the part of the data that has not been overwritten is still possible to be recovered, but in this case, even if it is recovered, the original file name and other information are also lost, and only some of the remaining content of the file can be recovered, and how much can be retrieved depends on luck, this does require professional data recovery personnel to do, and it is difficult to do it with simple recovery methods.

You should also know that in the case of professional data recovery, the cost is generally very high, because it takes a lot of manpower, material resources and technical means to restore it for you. It is recommended that you evaluate the importance of the data, and then comprehensively determine which data to recover according to the importance and possible cost.

If you only have a few small and important files, I can help you analyze the data corruption, if there are a large number of files or data is very important, please stop using the hard drive immediately, it is best to shut down and remove the hard drive, and then seek help from a professional data recovery agency. Do not use the software to try to recover by yourself, and do not read the data in the e-drive, otherwise it may further damage the file and increase the difficulty of recovery.

Overwritten data cannot be recovered, no matter what type of data it is, as long as it is overwritten, there is no way to get it back. If there is a backup of the lost data, try to restore the data from the backup.

If the file is overwritten on the hard disk, it cannot be recovered, but if the process is overwritten the text, it can be recovered.

If a Word document is stored on a hard disk and a file with the same name is later copied and overwritten, the source file cannot be retrieved.

If a piece of word overwrites the original text with another text, if the word is not closed, you can retrieve the source document by pressing the undo button. If you choose not to save, you should confirm that you did not click save during the process, otherwise it will stay in the state when you save, and the process save state may not be the same).

Ask how you know that it has been overwritten, a common sense is that as long as it is overwritten, there is no way to recover, no matter what, there is a follow-up data write, it will not necessarily be overwritten, and only after detection can you draw conclusions. If you need help, you can q me, I am manually recovered, first free detection and then recovery, the success rate is the highest, 1445207240

Hello, how big is your original E drive? How much data is there? How much data is covered? If the back coverage is greater than the previous one, then there is little hope.

Suppose the misoperated database is named tempdb and the recovery model is set to full.

1. Back up the logs of the database after misoperation:

backup log tempdb to disk='d:\tempdb_'

2. Restore the full backup you did before, assuming that the file name of the full backup is d: tempdb

restore database tempdb_2 from disk='d:\tempdb_' with norecovery

Note: The reverted database is named tempdb 2 and should not overwrite the library in use.

3. The last step:

restore log tempdb_2 from disk='d:\tempdb_'

with stopat='2009-06-04 23:50:00'

stopat represents the moment the database is to be restored to its state, that is, the time before you misoperate.

Commonly used hard drive data recovery software.

EasyRecovery is a very powerful hard drive data recovery tool. It can help you recover lost data and rebuild the file system. EasyRecovery doesn't write anything to your original drive, it mainly rebuilds the file partition table in memory so that the data can be safely transferred to other drives.

You can recover data from hard drives that have been damaged by viruses or that have been formatted. The software can recover hard drives that are larger than . Long file names are supported.

If the file is overwritten, it is still difficult to recover, but you can still use professional data recovery software to operate, and then you will know if you can get back the files you need. Here's how it works:

Step 2: There are three recovery options on the interface of the software, the user can choose the appropriate one according to the actual problem encountered and the function description, here select the "Quick Scan" option according to the situation.

Step 3: After that, there is the partition information of the computer on the interface, in which you can find the partition where the deleted file is located, check it, and then click the "Start Scan" button, the software will start to scan the selected partition, wait patiently for the scan to complete, Step 5: Click the "Browse" button to select the storage location of the file, and then click the "Recover" button to recover the selected file, after the recovery is completed, the prompt appears, click the "OK" button to view the recovered files.

Open Excel, press F12, click "Tools" in the upper right corner of the Save As window, and tick in front of "Generate Backup File". After saving the file, you will find a backup of the file with the same name in the same directory, and the suffix is xlk. Don't touch this file on a regular basis.

If you open the normal file and modify and save it, and find a mistake, you can open the backup file immediately.

It's the result of your previous save, and you can save it as the original file name after opening it.

Unfortunately, it is almost impossible to retrieve the overwritten files, you can take a look at the folder in that folder, the suffix is. tmp file, change it to an excel file, and then open it again.

The chances are slim.

Rearrange it and redo it.

If you want to open a little, pay attention to the next operation.

Good luck.

First install a recovery software on the computer, such as EasyRecoveryPro or the like, and then, try it with recovery software, if it is very important, it is best to install recovery software on another computer, remove the HD and restore it, the sector of the original file is not occupied, and it can generally be restored.

1. If all files are overwritten by data, generally speaking, they cannot be recovered by data recovery software (such as lost and easy data recovery) or general offline data recovery methods, but if they are not overwritten by data, files can be recovered through data recovery software. Of course, if you want to recover overlay data, under high-end laboratory conditions, there are still opportunities to recover through methods such as spectral scanning and data analysis, but it is expensive. And if you have a lot of coverage, these methods are not the same.

Here's a basic introduction to data overlays.

Data overwriting is actually very simple to explain, when we delete the data, normally in a short period of time, the data is still saved in the computer disk, but the deleted data, the display is marked with deletion, with time and new data overwrite, the data will really be deleted, so if there is a case of accidental deletion, be sure to stop using data read and write, non-stop reading and writing will let the new data overwrite the old data, so that the chance of complete recovery will become smaller. Data overwriting can be understood as data replacement, that is, the original data is replaced by new data.

Mini Rabbit Data Recovery: Data can be recovered normally without overwriting or corruption!

Therefore, do not write new data after data loss to avoid data overwriting!

You can install a computer manager on the computer.

Then select the toolbox and you can see there is a file data recovery tool.

With this tool, you can detect files that you have deleted by mistake on your computer and recover them.

Under normal circumstances, it is possible to recover the deleted Chinese files of the hard disk, and if the hard disk is deleted by mistake or formatted without other writing operations, it can basically be completely recovered.

DiskGenius can be used to recover accidentally deleted files

2. In the Recover Files dialog box, select "Recover Accidentally Deleted Files". If there is a write operation on the partition where the file is located after the file is deleted, it is better to check the "Additional scan for known file types" option and click the "Select File Type" button to set the file types to be recovered. Tap the "Start" button to start the search process:

3. After the search is completed, the Recover Files dialog box will be closed automatically. The main interface of the program will show you the searched files, each deleted file with a checkbox in front of it, and the entries in the folder hierarchy chart on the left will also have a checkbox. See diagram below.

4. Check the files you want to recover, right-click "Copy to" and select a directory to copy the files.

Wait for the copy to complete to recover the files.
