Hello,

i can't see a post with this as content so apologies if i'm repeating something that's already been posted...

I normally erase free disk space once or twice a year or so trying to keep my 2007 MBP, Santa Rosa, as fresh as i can. Since upgrading to Yosemite every time i try to EFDS it creates temp file, then goes through erasing the free disk space and at 99.9% through the process says something along the lines of:

Erasing free disk space failed, cannot create temporary file.

Anybody else getting this? any suggestions on what to do?

4MB RAM
about 40GB free on hard drive, roughly a third
no other apps running
happens on single, triple and seven times options.

liddle bit frustrating
 
Have you tried booting from a bootable cloned backup drive, and then used Disk Utility to erase the free space on the -internal- drive?
