Kid-Key-Lock and DiskDigger: Child Protect and Recover Lost Data

No matter how careful we are with the data we have stored on our machine, we cannot always keep an eye on it. If your child gets access to your system, who knows what could happen. It is thus important that you put your computer on lockdown with Kid-Key-Lock; and if your little one somehow manages to delete one of your files, you can easily recover it with DiskDigger.

Kid-Key-Lock, which is freeware and run on Windows XP only, performs a simple task: you can lock specific keyboard and mouse commands. Other, similar software applications can be easily bypassed by pressing Alt + Ctrl + Del and terminating the lockdown app – the guys behind Kid-Key-Lock realized that and consequently also blocked this command so that not even a technology oriented child could get past it. When you want to disable Kid-Key-Lock all you have to do is provide the password you set up. If you forget your password you will have to manually reset the machine.

If you insist on leaving your little one near your computer, then I suggest you make his random key pressing fun with Crazy Little Fingers.

Now, assuming you manage to give away your password and your child deletes the report you’ve been working on, you need not despair about the fact that you cannot restore it from the Recycle Bin. With DiskDigger you can recover mistakenly deleted data from any type on storage device: HDDs, USBs, memory cards (SD, memory stick). Unlike a simple undelete recovery that will simply go through your files looking for those that have been marked deleted, DiskDigger performs a brute force job of scanning the storage device and looking for any trace of recoverable files.

I think an explanation is in order: when you hit Delete, the data is not actually deleted (even though it is not in the Recycle Bin and you cannot see it any more). That disk space is simply marked as deleted, the data is still there and will not be removed until it is overwritten. That is what an “undelete” utility tool does: it recovers the files that have not been overwritten yet. DiskDigger does much more than that!
