What is the process of overwriting data media for internal reuse called?

The process of overwriting data media for internal reuse is referred to as clearing. Clearing involves the removal of data from storage devices in such a way that it is no longer accessible by normal means but allows for the media to be reused internally. This process typically includes overwriting the data with new data or patterns, making it difficult to recover the original information, but not to the extent where the media is physically destroyed or rendered unusable.

In contrast, purging generally refers to a higher level of data protection and often involves more rigorous methods, possibly rendering data unrecoverable by advanced forensic techniques. Destruction, in both forms mentioned, implies that the physical media itself is disposed of or completely destroyed, which goes beyond the scope of internal reuse. Thus, clearing strikes the right balance as a method that enables data to be safely overwritten while ensuring the media remains functional for further use.
