Erase And Format Crucial Ssd For Mac Os
Hello everyone, really hoping someone can help me out, i'd be very very grateful! Its come to the time to upgrade and therefore sell my old laptop. Its a mid-2012 13' macbook pro with an intel core i5 and 4gb ram. Originally it came with a 500GB hard drive but I have upgraded this myself to a crucial 480GB SSD. After I used time machine to back up my data, it came time to wipe the SSD. I did some research beforehand and was told a secure erase with multiple passes is unnecessary on an SSD, and I therefore followed apples instructions on how to prepare my laptop for sale: 1) I logged out of all icloud services, 2) restarted and booted into (i think) recovery or internet mode (command + R), 3) I went into disk utility, selected erase, selected my crucial SSD and erased it with the AFPS format, 4) I then reinstalled OSX High Sierra and created a new user. I wanted to test if the erase had worked, so I went on the internet and downloaded some free data recovery applications (Disk Drill and Easeus).
The SSD has now been formatted as a Mac OS Extended (journaled) volume named ‘MacOS’. Continue using this guide to format the disk as an AFPS volume, however if a Mac OS Extended (journaled) volume is desired you may now stop.

OCZ is only company who offers a bootable USB image with script that runs ATA Secure Erase commands on Mac’s. Any bootable linux image like ubuntu, mint, & etc has “hdparm”, which will allow you to run ATA Secure Erase commands.
After a few hours, to my horror, all my data came back, in the exact same path and was easily readable and recoverable. I did some more research and was told that encypting the disk would be a good way to securely erase the data (i wish i knew this beforehand!), so I turned on filevault, let it encrypt the disk and then went through the same stages again of wiping the drive with AFPS format. My question is, does firevault encypt data that has already been deleted? I ran the same recovery software for a second time, which again, found all my old files in the same paths, however this time I couldn't preview or open them once recovered.

Please can someone advise me on what to do? It's alarming me that the names of all my files are still easily found in the same directories with free software found at the top of a google search, but I don't mind too much if they cant be opened.
Is there something else I should be doing to permanently erase this free space? Is my data essentially safe? Thank you so much for anyone that can help, hopefully you can highlight a stage that I may have gone wrong at! The reason why your data was found again is because being in the user account that you used to turn filevault on, the volume is in an unlocked state. If you were to have it encrypted like you do now, use the recovery partition and erase it and reinstall the OS and give it to me, I would not be able to recover the data after I make my user account because the data was encrypted using the password you used to make the test user account.

If you would like to zero out or 'randomize' the bits on disk, go to internet recovery, go to terminal, type 'diskutil unmountdisk disk0' and hit enter, then 'diskutil zerodisk disk0' or, I think this is still a thing, 'diskutil randomdisk disk0' both of which will take a long time as they write data, either zeros or random, over the entire disk. If you ran the recovery software after this it will find nothing. EDIT: To answer something I missed, FileVault is whole disk encryption so every bit, even free space, is encrypted. The reason why your data was found again is because being in the user account that you used to turn filevault on, the volume is in an unlocked state.
