Has anyone had any success doing an ATA secure erase on a Retina MacBook Pro? Since the release of Mavericks and Windows 8.1, I thought it would be a good time to rebuild from zero. I have a 2012 15" rMBP and I'm about to give up. There just doesn't seem to be a way to unfreeze the SSD. There are some threads from about a year ago where people have had success, but none specifically with a rMBP. To be clear, I'm not talking about wiping the data from the SSD. I'm talking about resetting it to original performance. I have tried booting into a live Ubuntu distribution and performing the following using hdparm: http://mackonsti.wordpress.com/2011/11/22/ssd-secure-erase-ata-command/ You're supposed to be able to unfreeze the drive by closing the lid, thus putting it to sleep, then waking. Unfortunately, when I wake the laptop, I lose the ability to use the keyboard, and eventually the mouse. After multiple attempts, and searches on the web, I saw that some people had success by using Parted Magic. So I dropped 4.99 for it (it's no longer free) and... failed. I booted and loaded PM into RAM and ran the erase program, internal option. Clicked the sleep button but there seemed to be no way to wake the laptop. I had to hard reset. I tried with and without the USB drive in the port. So, as I said, I'm about to give up and just install Mavericks unless there's anyone out there who's discovered a procedure that works. Thanks!
