I've got a MBWE I with a 500 GB HDD. I've failed at every attempt to use Apple's Time Machine to back up to the drive and I'm done with it. I want to sell the drive because it's too much hassel and I don't have the time to fiddle with. I love having the drive not directly connected to my computer, but it's not worth it any more.
Anywho, I need to delete the data on the drive so nothing personal is on it. Is dragging everything to the trash enough, or could personal files be recovered after I sell the drive? If so, how can I securely delete all the data on the drive? Any help would be appreciated.
