El Capitan Disk Utility How to Format External Hard Drive with Secure Options?
Hey EE world, looking for a little help. It looks like the new version of Disk Utility that installs with El Capitan no longer gives me the erase options for number of passes written to the drive during erase. Any third party software that will serve the same function? Looking to do at least 3 passes on overwrite. Thanks in advance for the suggestions!

I see. I don't wipe drives directly from my mac. I have a box that I regularly switch hard drives out of, and just do it all there. I am want to take and move my mac more frequently than would support wiping of a 2TB drive with three passes.
Are you trying to erase an HD or an SSD? According to Apple, Secure Erase is not needed with an SSD: https://support.apple.com/en-us/HT201949 (scroll to the bottom). Secure erase will also shorten the life of SSD's.
If you are using an HD, you can in effect securely erase by turning on FileVault, then erasing the disk.

I have used DBAN before, it works great, but I am looking for something that can run in my life OS X session rather than having to boot to a disk. Any other thoughts? It was certainly easier when Disk Utility did this function.
