Does anyone have a recommendation of a free or very low cost product for doing secure file erasures?  Having secure free space wipe functionality would be a big plus.  Our main concern is that the software be simple to setup and use and be safe (basically, we don’t want the free space wipe to result in a bricked machine).  This is for a very short term use and management features are not desired.

 

Thanks in advance!

Have you looked at Eraser, http://eraser.heidi.ie/, for Windows?  We are happy with it and recommend it to our users, though, I have never used it to wipe free space.

I haven’t tested it, but I like the simplicity of interface for this one:  http://freeraser.en.softonic.com/

 

I liked Heidi a while back, but they seem to have taken away a lot of helpful functionality in the 6+ version.  (Plus I have stability problems with 6+ on windows 7).

I have the same reaction to version 6 of Eraser. I’ve been using very 5.88 in lieu of something better. It is still functional.

This was one I was curious about has anyone used it much?
Message from eric.lukens@uni.edu

Sdelete is good, I've used it to zero free space on VMs so they'll compact better. It's flaw is that it is only command line, but if only computer savvy people are using it or it is scripted, then it should be fine. Also for those thinking of using Eraser from http://eraser.heidi.ie/, keep in mind the installer is set by default to wipe *files* with the 35-pass Gutmann wipe. Since that is unnecessarily excessive, it may make people less likely to use it to wipe a single, larger file. If deploying it, I'd suggest changing the setting to either single or 3-pass wiping. Eraser is set by default to do just a single pass on free-space wiping. Trustworthy research seems to indicate that a single pass wipe is likely good enough for most of us for magnetic-based hard drives, and a 3-pass is more than enough. Of course, there are areas of the disk that will be bypassed even when using a full-disk wipe program like DBAN, so destruction is still considered superior to wiping. See http://csrc.nist.gov/publications/nistpubs/800-88/NISTSP800-88_with-erra... for more info. Lastly, remember wiping files or free-space on a solid-state drive (or a hybrid drive) is completely different due to the wear-leveling algorithms. Wiping using the secure erase command seems to be the only solution for a successful wipe and that is only applicable to the models that implemented the command properly. -Eric ---
Thanks all for the informative answers. As much as I'd like to use SDelete I think for what we're trying to do and who we are working with Eraser looks like a better option.
