Many people asks me this question that is it possible for them to recover data from their mobile device or from their laptop’s hard drive? The answer is very simple, Yes, it is possible to recover the data once you have deleted the data even from your recycle bin (in case of using laptop). This data recovery facility from mobile devices or from hard drive can be very useful for some people while it could be dangerous as well for other people. For example if you are using your computer and have your personal important data, family pictures and videos on it. Due to some mistake or some kid accidentally deletes your data permanently from your hard drive or mobile, then definitely you want to get your data back as you can’t afford to lose your data in this case.
But in other cases, when you have some important data on your hard drive and you want to sell your hard disk to buy a new one with greater storage capacity. You will transfer your data from old hard disk to new hard disk and then dispose off or sell the old one in market, or in case of cell phone, you want to exchange a mobile with your friend, you will delete your data from mobile after transferring it to new mobile and then you hand over the mobile to your friend. In both of these cases it might be dangerous for you that data recovery is possible. Because your friend or the new user who will use your old hard disk or mobile can recover your important data, your credentials, your family pictures and videos which you don’t want to show to any other people. So we can say that data recovery facility is useful and harmful for different people.
