As we all know that
formatting a hard drive will not permanently erase the data from the drive.
Even when you delete the partition, the data on this partition cannot be read
by system but the content of data still stays here. If you sell your computer
or send it to others, they can easily recover your data with data recovery
software. Therefore, you have to handle your unused computer correctly to
secure all the data on the drive have been completely erased.
Data
wiping software
The most widely used
data wiping software is DBAN, which is a popular and free tool can help you to
complete delete the data on the hard drive. It is very simple for all of us to
use. Once the data are completely destroyed by DBAN, no one can recover them.
Download the Dban
software from the website and then boot your computer from the USB stick. If
you do not have a bootable USB, you need to create one. The system will
automatically enter main prompt, enter the command of autonuke and then press
enter. The Bban will automatically starts to wipe the data. The wiping process
may take you several hours, the time depends on the size of your file. After
the wiping process completed, the data have been completely erased and
unrecoverable. If you accidentally use the Dban to wipe your data, you should
stop this process to reduce the data loss.
Use
hard drive eraser
The hard drive eraser
is a device designed to help you wipe hard drive. It is very cheap and easy to
use. You just need to press the button on the device. If you have different
hard drive to wipe, it really useful to easily wipe the data.
Format the hard drive
after you have encrypted it. If you perform a full disk encryption on the
drive, no one can access to your data. After that , you can perform a format.
In that case, formatting will permanently erase your data. Then you have
successfully secure your data.
The last way may be to
physically destroy the hard drive so that the data become unrecoverable. You
can use a hammer to destroy the hard drive but may seems unwise.
At last, I would like
to remind you that do not forget to back up your important data before you are
planning to erase all the data. All the data recovery software can only recover
the files that have not been erased.
To recover data on HDD,
you should take data recovery
