I currently have my internal HD partitioned into two chunks. One runs my OS and the other is an old Windows/storage partition. I'm running a MacBook Pro 2.2 Intel Core 2 Duo. I have a plan and I want to check if any one here thinks there will be a problem, or might have another suggestion. I want to do the "7-Pass Erase" on the second "storage" partition. Totally clean it up. Then do a complete install of the OS from DVD onto that partition. Using Boot Camp, start the Mac up on that second partition and do the "7-Pass Erase" on the "old' OS number 1 partition. Then I'll be running my OS on the second "old storage" partition. Dose any one see a problem with that? Dose it make sense? Is there another way to do a complete "7-Pass Erase" on the entire drive. I have very sensitive information I need to be sure is deleted, and I'm lending on my system for a couple months. Also, will 13 GB cover the install of the OS on my second partition? Thank-you so much.
