Hello Guys,
I would like to use the the native ATA SECURE_ERASE function to wipe my SSD drives and restore their performance.
My current platform is FreeBSD 9.0 and I have discovered a couple of patches for the secure erase function, but they appear to be out of date.
The first one was a perfect implimentation for atacontrol (http://www.roe.ch/ATA_Security). It was submitted but rejected with the explanation there will be no more development on atacontrol as camcontrol will be the common access interface (yay!!).
The latest effort that I was able to find was somewhat of a port of the atacontrol patch effort to a camcontrol patch for FreeBSD 8.2 (http://blog.multiplay.co.uk/2011/08/freebsd-security-support-for-ata-devices-via-camcontrol/). This was almost perfect, but I am running v9.0.
I'm very much of a newb when it comes down to compiling or making patches, so I have two questions for this thread:
1) Is there a way to use ATA SECURE_ERASE under FreeBSD v9.0?
2) Can I apply a patch written for FreeBSD v8.2 camcontrol to v9.0?
I tried to apply the patch but I did not get a return status:
FYI - I did not modify the 8.2 patch.
Any help would be greatly appreciated.

ATA_CAM option is enabled in kernel.
Please use camcontrol instead.I'm very much of a newb when it comes down to compiling or making patches, so I have two questions for this thread:
