Sandisk Rescue Disk Question

Well I thought I had got rid of all my pictures by deleting them via the camera. WRONG, used the rescue disk and there they all were, so formatted the disc hopefully will get rid of the unwanted photos, just run erase (not wipe) and it said all settings now back to zero, so hopefuly that has got rid of them.

What I was wondering is how much memory on the card is used up after only deleting via the camera.

Don't know Bazza, but it is nice to know the rescue disk works

I don't really understand this question? do you mean something like this...

When you delete a file (which may be an image or a Word file etc.) on a computer (or camera) the actual data isn't deleted only the first letter of the file name. In effect this means it can't be seen by the indexing system and for all intents and purposes the file is no longer there. If the storage medium, card or hard disc, was never used again software like the Sandisk Rescue disc merely reinstates the first letter and consequently the file can be seen again. If however you use the storage medium again by usng the computer or taking and saving more pictures before restoring the data or indeed never restored the data the data space will either immediatly or eventually be overwritten.

If you deleted all your pictures your card would appear to have as much free space as if you freshly formatted it because simply the index would show it as empty. When you format it is like setting up the filing system and cupboard space again and technically makes it more difficult to recover anything that was previously there (but not always impossibly so). You will notice that your card never actually has as much free space as it says on the box. A 2gb card may only hold 1.86Gb. That is because effectively some space has to be created to makes lots of compartments to hold your files and also a reference index (file allocation system) to tell the camera or computer where it is within that system.

Sorry for the long reply but hope that may answer your query and help anyone else understand it.

As an aside, a perfect example of files being deleted but not really gone, only hidden from the computer index is all these people being done for child porn or fraudulant accounts. They think files are destroyed when they delete them but police using a much more sophisticated version of your Sandisk type software can still prove they are, or were there.

Thank you BC.
