Simply buy their 2nd hand drives, that IT didn’t erase, because IT is underpaid and undervalued in a lot of companies. Most companies that get rid of their drives physically destroy them as it takes a lot less time.Īlso, some companies don’t at all, which is a great way to find company secrets. Normally formatting takes a minute (it’s only deleting and rebuilding a new reference list). I believe it’s an option when you go into the disk utility and want to format a drive. Or write those zeroes on the entire disk seven times.

Fun fact, there are options to delete a disk and then actually write zero’s on the entire disk. Edit: I did a quick Google and found Disk Drill allows the first 500 mb to be free. I accidentally selected too many packages for update, like hundreds of them by doing. You might want to Google for alternatives that are cheaper or free. Recoverit is one program I had success with (finding deleted audio files on an SD card and finding erased pictures on an SD card). If you don’t have access to another Mac and cable that can connect the two, you can still try it on your Mac itself to scan your disk. Look up “disk mode” to see how you can turn your Mac into a big hard drive and connect it to another Mac. It’s a good idea to turn off your Mac and use another Mac to perform the search.

Sometimes, your computer needs more space for it’s calculations and will use your hard drive to temporarily, and invisible to the user, store it’s data). But the bits are still there, when they’re not overwritten yet with a new file (or, with files from your RAM. When you delete a file, the bits are often not erased, as this takes time. When you navigate to the file, it uses this reference list to find the actual bits on your disk. (It’s $76 for a one month license: )Īs far as I’m aware, files are written somewhere on your disk and then placed in a reference list.
