If your computer does not have a data recovery disk, then you will face problems once you lose a file that you desperately need to recover. Such disks guard your computer from drivers, system components, drives, and application troubles. One can differentiate two types, one where operating system files can be recovered and another where data files are stored.

The key of course is to back up your system. Once you do so, recovering data such as emails, text files, or anything else you can think of is very easy. Any old rewritable CD where data or any other recent saved files can be written and re-written on it again and again is suitable for this job.

Of course, there is another kind of data recovery disk saves things such as deleted partitions or even corrupted files. Such a disk will most likely contain data recovery, disk image, password resetting, partition management, system utilities, data erasure as well as network access tools.

Anyone can buy a data recovery disk varying on the kind of recovery that can be made. Most disks have certain specializations. You can set them to recover images only, or e-mails only or anything from your hard drive. You can even recover data from any removable disk.

The operating system disc (usually drive C) can also be used to recover data. One just needs to boot from there then you run any of the following depending on what kind of recovery you want to do. These run commands are either fdisk, chkdsk, or testdk. Just press F12 when the operating system is starting as you turn the PC on. You could also boot from a CD or your disk. That will enable you to get inside and fix the kinks out.

There are however, some special circumstances when data recovery is no longer possible. And this is funny because there are those who think that banging or dropping the computer, or even heating it can fix it. Of course most of the time, this just makes the problem worse.

Of course, a computer that has been hit or fallen will have physical damage. During this kind of circumstances, your hard drive might just be damaged. Then you will never be able to get back that lost data. The most you can try to do is to pay the guys from crime scene investigations to have a look at your data. But that is of course highly unlikely.

Therefore, as a warning, one should never do anything silly as physically banging on the PC if you are only looking for attention. Simply use disk to back up your data most of the time as well as other tools for recovering data. Remember though that some day, your pc will go bust. This is why one must be ready by backing up or having a data recovery disk.
