Perhaps you would like to post if you are using XP or Vista and which version of recuva.
Also is this something that has just started happening with recuva.
I have attached another screenshot as I have continued to let it run, it is now at 578%. I am using XP Pro SP3, all of my computer details are in the new screenshot, including the version of Recuva.
I have not used Recuva before, so I am not sure if this is new or not.
Another screenshot, now at 1033%.... I need to cancel this at this point since it has been running for about 3 hours and going crazy the whole time.
I also ran Recuva without those options and it worked just fine and showed me a bunch of deleted files, so it is working, it just seems to not work with those two options enabled.
