How to Wipe a Mac Mini Hard Drive

To wipe the hard drive of a Mac Mini, you must zero all the data on the disk. Computer information is in binary, zeros and ones. These zeros and ones are behind everything you see on your computer. When you zero out the data on a hard drive, all of the binary changes to zeros, a state the Apple website refers to as “digitally blank.” Zeroing out data is irreversible and files will not be recoverable, so make external copies of any information you value before you begin.
