Your thoughts on data security when recycling? thanks. What is your level of comfort regarding how you choose to remove data from these newer SSD drives for the purpose of recycling a Mac? Or would you open the computer and destroy the SSD? I've had that thought. And such erased is recoverable I think if someone was so inclined. But what about the SSD's where you can't do that? Would just erase and be happy? I just have family business type stuff on the drives that I erased long ago but not yet the entire drive. The 2009 is a HDD (two in fact one I once put in in place of the CD (remember CD's?) and is HFS+ I think.Īpple did away with the ability to overwrite drives what 1, 7 or 35 times or whatever it was? when they went to SSD's because they said the way files get stored on SSD's, that method of eliminating data doesn't really work or something like that? My guess is I will be able to overwrite the 2009 HDD's if I choose to go to that trouble. If you choose the wrong drive identifier you may lose data on another drive/device. The 2013 is SDD and runs Catalina (APFS). Once all the volumes on 'diskN' are unmounted, you erase 'diskN' using the following command: sudo dd if/dev/zero of/dev/diskN Note: Remember to substitute the correct identifier in place of 'diskN'. What are your thoughts on simply erasing disks and then recycling for perhaps some next guy to have the old computer? I have a 2009 and a 2013 MacBook Pro I want to recycle.
