Had a long day of work and decided to clean up my hard drives with my fav program eraser. One thing I never used is the feature of replacing erased files with another file instead of seeing zeros when deep scanning my drives to see if eraser done its job, and it does obviously. I need some suggestions on what files to use. I was thinking of just downloading a bunch of open source software, os's like ubuntu xubuntu freebsd etc. and use that. Or maybe just using one of my windows 7 folders like the inf directory or system32 directory. I dont have a real need to be paranoid about what i have stored on my HD, but I do want to know what would actually look legitimate to someone who works with comp. forensics.
