I got the idea to do this test from the System Spy Test thread started by Clone Ranger: Here This is what I did. I disabled Returnil and wiped my hard drive. It is 650 G and is empty so it took a long time. I then started virtual mode and enabled virtual mode upon restart. I double checked just to make sure that "wipe all disk changes" was checked. I checked both before and after restart just to be 100% sure. I hooked up my external hard drive and transferred a bunch of folders. I have a huge collection of animated gifs and pictures all organized by type so I had a lot to transfer. I then unhooked the external hard drive. I deleted several of the folders and I left several on the desktop. I then restated my computer. Since I had so many gifs (possible 2 or more G's), I decided to give Returnil plenty of time wipe everything. I went into the kitchen, did some dishes, took out the trash and did some cleaning etc... (20 to 30 minutes). Then I went in and restarted the computer again with virtual mode still enabled upon restart just for good measure. I did a few more chores and then went into the control panel and unchecked the "start virtual mode when I start windows" option, and restarted my computer. I then opened up Recuva, chose the picture option on C drive, and checked the "Deep Scan" option. It takes a couple of hours on this computer. The vast majority of the image slots said "no preview available". But the bottom potion of the results page showed a large number of my gifs. And they were completely recoverable. It in no way showed them all. But there were a lot. I want to be clear though that I think Returnil is a wonderful product. I absolutely love it. But one improvement that I would like to see is a better wipe option. But I don't know if that is possible. It may not be. If I had to choose one product to protect my computer it would be Returnil hands down. Nothing that I know of compares to it!. And it continues to get better and better with constant improvements.. I just want to be clear about that.
