Example 2. Suppose that you have taken ten pictures, have deleted three, and taken another picture. In this case, the newest picture overwrites one of the deleted images. If you recover the hard disk, you will obtain 10 images, nine original images, plus the latest picture you have taken. The exact location of the overwritten deleted image can not be predetermined. The picture you deleted that was overwritten with a new image cannot be recovered.
Example 3. Suppose that you have filled the PCMCIA card with images, and erased all images. If you recover the disk with this button before you take any additional pictures you will have recovered all of the images you erased.
Example 4. Suppose you begin with a blank PCMCIA card. Over time you have taken pictures, erased the disk, taken more pictures, deleted some, taken additional pictures, and so on — never having more than 20 images on the PCMCIA card. As you take new pictures while there are still active images on the PCMCIA card, the new images are written into an empty location on the PCMCIA card; deleted images that are overwritten become unrecoverable. Suppose you now delete all images and take three new pictures; the three new images will overwrite three images on the PCMCIA card. The exact location of the overwritten images can not be predeter- mined. If you recover the PCMCIA card, you will recover 20 images; the three new images plus 17 of the most recent 20 images.
