If I use third party software to wipe the unwanted data, I actually write bunch of 0's and 1's to the hard drive in order to block that the data I wanted to erase.

The different levels of secure deletion are reasonable for many perspectives:

• Permanent/ Temporarily: Some data we might don't want to keep anymore, however, some data we might don't need at this point. Thus, we need to separate
