Hi. I have a question. I deleted some files on my hard drive. Will the information that is left over which would allow you to be able to recover be overwritten first when you get new files or shred freespace, or would you have to completely cover all the freespace. I was wondering because I shredded 10% of my free space with just one pass, it took a half hour just to do that, and also moved Gigabytes of files to the Drive. Then I went to download a program called "Restoration," which can find deleted files without scanning I believe. Nothing showed up. Does this mean they are already gone for good?It's a new hard drive that I''ve only deleted several Gigabytes of things on and still has hundreds of Gigabytes left. Does it delete the freespace with deleted information first or does it not differentiate? Also, would the files be unrecoverable with just one pass and new files being placed in the freespace? Most of them are larger files but some are smaller. For Example, I did a one pass of shredding freespace on a drive with only 15 Gigabytes of freespace, and then when I scanned it with "Recover My Files," there were still some image files that were intact from temp internet files.
