How can I trick a memory to write new data in fresh locations only?

Hi, so recently I had to save data from a 3tb external memory, and along the recovery process I found files I had deleted a while back, which I expected.but some of the images were broken because new
data Was written on the deleted area. (as it should)

p.s. I understand how a hard drive works like a book with an index, and when you delete something
Usually you delete the"index" but as long as nothing new is written on top of that location, the original
Information remains intact.

So I was thinking, is there a way to "trick"the system so that even though the item has been deleted
The computer will avoid writing new data in old locations until it is absolutely necessary?

What I'm trying to do is, protect data from being deleted even after someone (intentionally or by
mistake) deletes something from the memory.

Eg. A memory contains 10 blocks. I add music to blocks 1-5, my brother comes and deletes those songs
Songs and then go on to download a video. in a normal situation I would lose those songs for ever from the memory and the only recovery would be to download then again.
But instead with this "trick" the computer writes the video my brother downloaded into blocks 6-10
Leaving 1-5 untouched for the time being, allowing me to see this and use my recovery program to save my files.

I theres anything like this possible?
what I explained was on a OS, could that be done on a memory card?

thanks for any help

There are programs out there that will 'nuke' your drive, deleting everything and writing random data on it over and over again. Not sure about it writing new data over previously used space.

That's not what he's asking for.

To the OP - I am unaware of such software to do as you ask.
 
This doesnt make sense..... so you want to be able to delete the index but keep the files? You would end up running out of space really quick if there was such a program that could do so.... but I dont think its possible.

You could always try to use recovery programs to recover deleted data that is still intact on the drive, alot of them work just fine but as you said they can become corrupted when new data is written over them but if not they will be like new.
 
Well ok so there really isn't anything. yes I understand it would use the memory up fast, but I guess this goes into security what I wanted to do goes against the safety measures placed by the system. like ext, fat, etc...

Thanks anyway

Its not a safety measure, its just how it is. When you delete something, it becomes deleted and the system is free to write over it again. But as long as it stays in the recycling bin, it wont be written over. So, hide your recycling bin and then if someone deletes something its not really gone and if the bin isnt on the desktop maybe they wont know where to find it.
 
Well yeah, but I was looking for something like that to be done on memory cards.
Maybe make everything saved in the memory automatically makes a copy in a hidden folder?

You can delete them and have the index saved, see this post: ;)

But if he is referring to a memory card, like say a flash drive, then the recycling bin will not work as the system does not take it to the recycling bin when you delete something off an external storage device because the data on the device is not linked to the operating system.

I actually do not think you can save data that has been deleted on something like a flash drive other than using a recovery tool. You can, as you say, try to hide copied folders.
 
Fair enough :)

You would hope the flash device's firmware would be smart enough to roughly even wear the cells though.
 
G80ftw is correct I'm giving examples, but my idea is about any type of memory, 4gb flash, micro, cell phone memory external memory, etc.
And to.cromwell, I'm actually going to test that, using brand new never used 4gb, I'm going to write a single 1gb file and a 1gb of a few large images. Then delete then, then copy a single 2gb file and delete that as well, then use a recovery program and see what gets record.

Any other suggestions about how to do this trial?
 
If you are afraid that something or someone might delete your data of some flash drives,put all your data in one folder and then at the beginning and at the end of the folder's name write the dots---> ":::MY FOLDER:::".

Windows operating system cannot do anything with the files/folders which contain those dots so it cannot be changed,moved,copied and deleted.

However since Windows operating system cannot work with those kind of files/folders,you will need to put those dots using Linux Ubuntu CD-ROM disk.But it's not hard...just boot to the Linux Ubuntu CD-ROM disk and put the dots.Once you need to work with those files/folders in Windows again,just boot to Linux Ubuntu CD-ROM disk again and remove the dots.

Note: even the files/folders which contain those dots CAN be deleted if the user formats the entire media using tools such as Disk Management in Windows OS.But I would not worry about that since many people do not know how to do that.
