Otherwise when you deleted a 1 gigabyte file you’re disk free space wouldn’t go up by the same amount! However, once it has been overwritten (in whole or in part) by future files like videos, emails, documents or resources used by your operating system, the physical area on the disk may or may not right now be in use. Your files should disappear from the Mac Finder, and assuming you have your volume turned on, you’ll hear the familiar crunching noise of the files going into the Trash. Press the command delete keyboard keys at the same time. When a file is removed the normal (non-secure) way, the physical space on disk although not overwritten is now available for other files to be written to.

There is a disadvantage to using Guttman’s method: The process is a whole lot slower than the DoD’s method and obviously orders of magnitude slower than a standard delete. Very clever, very scary.Īnyway, the DoD specification reads quite simple compared with a data overwriting algorithm specified by a guy called Guttman which basically entails random data repeatedly written over the data thirty six times. However, remove those letters and although the information cannot be read by the naked eye specialist data recovery firms (and law enforcement agencies) have methods and tools to retrieve the fingerprints just like they were ghosts or shadows of the original data. Consider a fridge door with magnetic letters spelling out a message. Basically hard disks are like magnets and file data is stored as magnetic fingerprints (yes, this is highly simplified) on those disks.
Now, the US Department of Defence specifies certain requirements about the overwriting process to ensure the chances of recovery are limited. If you want to select multiple files, hold Shift and click all the files you want to select. Alternatively, you can right-click the file, if your mouse or trackpad has a right button.

Under Linux I always used wipe within a terminal to securely delete my files, and I was about to purchase “ShredIt X” to essentially perform the same thing under Mac OS X when I came across a comment on a software download forum mentioning srm. Mac users haven’t been so lucky, until the release of OS X 10.11 El Capitan.
