It is quite a frustrating moment when you put all their efforts for some project on your computer and then it is all lost.
It is quite unfortunate that after all the hard work, the data that was saved is all lost. One of the factors that lead to loss of data is when your hard drive crash.
However, hard disk recovery tool can come to your aid. Nowadays, most data recovery software are designed to be user-friendly and simple to operate, therefore most users should not have much problems with it.
When it comes to files that have been deleted by mistake or even deliberately they can still be retrieved. You just need to know the procedures to do it.
They are many ways to find free hard drive recovery tools online. Most download directories such as download.com offers hundreds of free data recovery tools. However, some are demo versions and usually requires you to pay a upgrade fee for all functionalities.
However, I find that most paid data recovery tools are better than free ones and the cost is quite affordable, usually under $50.
Most data recovery software have common functions such as retrieving files after a partitioning error or from RAW hard drives, an accidental format, files that have been emptied from the recycle bin, it can even recover photos music videos and emails and can also from cameras USB and so on and so forth.
However do note that, for physical HDD failure such as read/write disk head failure, hard disk platter scratched or crashed, it will require the help of a professional data recovery professional.
In most cases, recovery of the data is not guaranteed and the cost can be quite expensive. Typically, it can run into thousands of dollars.
Therefore, the logical thing to do is to backup your vital data regularly. It can save you money and problems in the long run.
