=Concept Map=

The students will be mapping out the main concepts that are involved in recovering deleted images on a SD card. The map should begin with viewing pictures and then the picture being deleted and the rest shall be the general stages that are involved in recovering the image. There are many sites out there to create concept maps but one that you can use is [|Gliffy](this is a free website that lets you have up to 5 documents saved). Along with the creation of the concept map a brief reflection should be written up explaining the concepts that the students have come up with.

My Concept Map

 * Reflection** - At the center is what the whole process is about, digital camera pictures. From there we move out into the process, the first one being "view pictures" which is what we all want to do with our pictures. Moving in a clockwise motion the picture would be deleted somehow and we would want to get it back. From there everything is grouped up, the first is getting HxD, the user would have to open Internet Explorer, Google search for HxD, and then install it. Once the program is installed on the computer the user would remove the SD card out of the camera, input it into the computer and use HxD to open the SD card. Next they would automatically be viewing the boot sector; the user would map out the rest of the SD card from the information in the boot sector and would then find the FAT Tables and Root Directory. The user would then go to the root directory because that’s were the file information is stored; they would be able to find out how large the files were and edit the root directory entry to recover the deleted file. With now knowing how large the deleted files were they would go to the FAT tables and reconstruct them. Once they are done completing the FAT tables the revisions to the SD card would be saved and then it brings them back to the beginning and the user would be able to view the pictures.
