Hardwipe is a powerful data deletion program today, it uses the file deletion mode by overwriting, the data after deletion will not be recoverable. To know how to use Hardwipe, please follow the steps below.
Instructions to delete data from your computer with Hardwipe
Step 1: Download and install Hardwipe on your computer.
Step 2: After installing the software successfully, you set the delete mode on Hardwipe by going to Tools ->Options
– Switch to tab Wipe Options, in section Default Scheme Allows you to select the deletion mode:
+ Zero Overwrite (1 pass): Clear data by overwriting 1 time
+ GOST R 50739-95 (2 passes): Clear data by overwriting 2 times
+ DOD 5220.22-M (3 passes): Clear data by overwriting 3 times
+ Schneier (7 passes): Clear data by overwriting 7 times
+ Gutmann (35 passes): Clear data by overwriting 35 times
Usually you should use DOD 5220.22-M (3 passes), when deleting data will overwrite 3 times so data recovery software is also difficult to retrieve deleted data by software. If the method of deleting overwritten data is less, the deletion time is faster but it cannot be equal to the method of deleting overwritten data many times. Gutmann (35 passes) is still considered a fairly effective method but the removal time is very long.
Step 3: Delete data with Hardwipe, right-click on the file or folder to delete and select Wipe File, the deletion process is very fast. And the file, folder you just selected has been deleted from the computer.
– However, to delete this data more thoroughly, on the software interface you enter Free Space. A window appears, select the drive (this drive contains the data you just deleted from) and press OK, got it. This will completely eliminate data and space when deleting data created on the computer.
Above, Taimienphi.vn has instructed you to permanently delete data from the computer with Hardwipe, so that you can apply and delete unnecessary data on your computer.
