I can't seem to find anything identical to my case so I figured you guys would know. What happened was I sold my Seagate external HD on amazon that I previously used for time machine. I did the "erase" function in disk utility but I did not use the erase free space option because I didn't understand what it would do and I was in a rush. So basically my question is, how secure is my information of TM against hacking? Also, I formated it for FAT32 for windows users, so I dont know if this will affect anything. Thanks in advance.
