    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?
