I got a question i was wondering about. Say i delete a couple of files from ma hard drive and then i defragment. Does that make a difference when trying to recover deleted files? Is it possible after defrag then to recover? Thanks
Doing a defrag can certainly lessen the probability of recovering the files you are talking about.
However, it depends on where the files where when you deleted them and the defrag process itself (and the logic used). The main "concern" is that you do not have a lot of control on this process, so you are left unsure.
If you want to delete a file, use tools like BCwipe, it can wipe freespace. If you are focused on recovering, a defrag is definitely bad, but it does not have to be a case-breaker.
