We need data recovering when something bad happen to our computer, because data is the most important part in our computer. Data recovering can become an easy process when we know how to do it; just like when we are do not intention deleting our important files. In Windows operating system when we delete our files it is will go to the recycle bin first and we can recover it easily, but what about happen that the recycle bin has been cleared or maybe the deleting process do not go to the recycle bin. This is bad because we do not know how to recover it.
The truth is that all of the files that have been deleted from the harddisk do not exactly erased, but the thing that erased is the pointer location to those files that has been erased. Because there are no pointer to the files, so the operating system will consider that files does not exist. To get the access to the files again we need an application. This kind of application called recovery application or undelete application. This kind of application is able to recover files or undelete files by looking the files location without have to depend to the file pointer.
But there are something that we must do to make the recovery process or undelete process easier so it have great potential the files can be recover, and that are:
- Files recovery process must do quickly after the files has been deleted.
- Before the recovery process do, we must not save new files that has the same name with the file that has been deleted because this new files will have potential to rewrite the files that has been deleted.
So, if we all know all of this, it will make the data recovering process faster and easier.
