What is data erasure/ wiping?

Data erasure (also called data wiping) is a software-based method of overwriting the data that aims to completely destroy all electronic data residing on a hard disk drive or other digital media. Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to the data disk sectors and make the data recovery possible with common software tools. Unlike degaussing and physical destruction, which render the storage media unusable, data erasure removes all information while leaving the disk operable, preserving IT assets and the environment.

Why should we wipe data?

If you run a file-recovery utility, you can recover data from these “unused” sectors, assuming they haven’t been overwritten yet. So if you have some important or sensitive data which you don’t want others to get, you must delete it completely and make it unrecoverable. This when we need data erasing tool.
