Will be moved to the original hard drive, and restore all your personal files from the backup image.. ' The fact that, currently, the only DoD/NSA approved SSD sanitation procedure is somewhat echoes the challenge in being able to wipe a drive, for sure.. The data isn't necessarily encrypted, but it is distributed data over many locations in order to perform as few writes as possible to a single location (both for performance and for drive longevity).. , i e They generate a random key and store it in the disk's metadata and encrypt all data stored to the drive with that key (additional explanation ).

I'm a couple years late to the party, but it might be worth pointing out that Apple (who has now entirely remove 'Secure Erase' options from the Disk Utility app) hasn't really removed the option because it 'isn't necessary' according to its, they did it because they can't guarantee a secure erase: Description: An issue existed in guaranteeing secure deletion of Trash files on some systems, such as those with flash storage.. These options are not needed for an SSD drive because a standard erase makes it difficult to recover data from an SSD.. When I use Disk Utility's Erase button on an SSD, the Mac clears out that key, so even though the data hasn't been overwritten, it's all inaccessible ciphertext now that the key is gone, and is as good as zeroed-out..

These options are not needed for an SSD drive because a standard erase makes it difficult to recover data from an SSD. b0d43de27c 4
I'm about to trade in a 2010 MacBook Pro with an SSD However, I'm unable to do a Secure Erase from the recovery disk (as I used to do with mechanical hard drives before selling or giving away a computer) since the 'Security Options' button is grayed out.. So once data is deleted, find the place a file used to reside in is like putting together a multi-million piece jigsaw puzzle (all before any garbage collecting the drive may decide to do). HERE
