Some of you know I tend to change cameras nearly as often as I change my sox but got to thinking today. On Monday I picked up a second hand Fufi HS10 which came with a 8GB card. Unfortunately it was a Class 2 so I ordered a Sandisk Class 10 replacement. Now Sandisk come with a card recovery program called Rescue Pro (used to be free - now it's a 12 month subscription). I decided to see what it might recover from the original card and sure enough it turned up well over 100 images despite the card having been re-formatted by me. After a quick look at a couple of images it was clear these were typical family shots. Formatting clearly does not remove all traces (it alters the marker that points to the file so the camera does not see the file(s)). Rescue Pro does come with a card wiping program that overwrites everything taking nearly an hour for an 8GB card. Now in the past I've sold cards with cameras and any recoverable images would be harmless but it makes one stop and think. Of course the same technology applies to hard disks and thumb drives.
