When you delete a file on a hard drive, the data in it isn’t really deleted at all. Instead, the system marks the deleted file as no longer accessible and marks the space occupied by it as deallocated (free). After that, the space can be available to use again when new data is written to the disk. That is why, until the space is overwritten by new data, you can recover the deleted file by using data recovery software. Meanwhile, anyone can easily recover your deleted file through unauthorized access.
In order to wipe out deleted data on the disk without recovery and protect your privacy, you could take the help of Windows built-in “Cipher /w” Command or Wise Care 365. Please continue reading on.
What is “CIPHER /W” Command
The "CIPHER /W" command is a command used in Windows to overwrite the free space on the specified drive with random characters. This command is often used to ensure that previously deleted data in the drive is virtually impossible to be recovered.
Steps to overwrite the deleted data by using “cipher /w” command:
It does not overwrite undeleted data, so doing this will not remove the files existing on the disk.
- Press Windows key + R to open the Run dialog box.
- Type “cmd” in the text field.
- Press the Enter key.
- Type cipher /w:? command in the Run app. “?” stands for the drive you want to wipe. For example, the cipher /w:e command causes all free space on drive E to be overwritten.
- Close all other apps before running this command.
- Then press Enter key again.
- Close the Run app after overwriting.
