Release the key when you see a small spinning gear appear below the dark gray Apple logo. The Mac OS X Disk Utility app provides an ability to erase free space on traditional hard drives, which overwrites vacant disk space on the drive to prevent any potential recovery of deleted files that is, files that have been removed traditionally, rather than through secure methods. Yes, this only works on traditional hard drives of the spinning platter variety, which is typical for MacBook Pro, Mac Mini, and iMac models, and is the case with most external hard drives used for backups.

This option is not available for flash-memory based SSD models like those bundled within the MacBook Air, Retina MacBook Pro because those drives use the TRIM function to quickly remove and recover blocks instead, which has the side effect of automatically preventing file recovery fairly quickly — often within 10 minutes of emptying the Trash.

Keep in mind that the latter two options take longer to complete, because they are performing the same overwrite task either 3 times or 7 times. Of course the difference here is that this trick focuses only on securely erasing the free space i. This makes it a great solution for situations where you clean up an existing OS X installation for a new owner and want to preserve things like installed applications, but do not want any of your deleted personal data to be potentially recovered by anyone.

Again, this is largely unnecessary for most users, but it is good practice to erase free space on any traditional hard drive that will have ownership transferred. This can also provide for a delayed alternative to using the secure empty Trash function of OS X if you decide later that you want to prevent the recovery of some files that were deleted.
