Which is more expensive? A computer or data inside it? In my opinion, the most expensive is the data. If the computer is damaged, we can still buy a new computer. If the data of our work gone, which was years effort we made has been lost, what can make it back again? it can possibly get back, but not as easy and as cheap to buy a new computer. And also not necessarily the data will return intact.
That’s not to underestimate the data storage medium of our work. Be helpful to have another planning before data we actually damaged or lost. The first thing we must recognize are what are the cause of damage or loss of data, namely:
1. Virus attack
2. System (OS) Crash
3. Hard disk Crash / damaged
4. Accidentally deleted
1. Virus attack
For the first cause is a virus attack, the file can be lost or damaged. File2 is nothing to return or not depends on a virus that attacked ferociously. There are viruses that only our file2 hide or change the file extension into other files. For this, we can find again. But there are malignant virus that can delete files in your computer permanently. Well, for this one, we can cry for a week 
2. System (OS) Crash
The second cause of the OS crashes. If we are using windows and had crashes, the first way is to make recovery from the windows CD. But if the recovery fails, then the other way is to reformat the hard drive and install a new OS. What about our data? Surely, if the format helped drive lost data would be formatted.
3. Hard disk Crash / damaged
The third cause lost of data is Hard disk crash. This cause by hardware problems, especially electronics. We can not guarantee an electronic device can run forever. When the disk has started out suspicious sound, that’s when the hard disk should be retired. We truly hard drive crash / corrupted, the data in it will go away automatically. Indeed there is a way to take back the data stored. Just stay to take special shop repair disk. They specialize in saving data, but does not guarantee the data also will be back in full and of course the price could be very expensive.
4. Accidentally deleted
The fourth is the cause of human error. Data accidentally erased. If only erased recycle bin and go, you live restore again. But if removed permanently, it seems difficult to go back. Similarly, the second cause, there are some techniques to get the data back but not necessarily with high paying cost of recovery.
For that we need to prepare themselves well before all this happened. You would not want his work over the years lost in an instant. For example for writers whose work has a lot of sediment on the hard disk contemplation of lost years caused by a virus. To that required some effective preventive measures, namely:
1. Make a different disk partition for the System (OS) and the data.
Suppose you have a 80GB hard drive, make it two partitions for Windows (usually drive C, 30GB) and for data (usually Drive D, 50GB). The virus usually will attack the system. So when the system crashes due to virus attack, we can easily do a full format and installation of new systems. Data stored on another partition will not have to formatted. Causes damage to the first and second could be handled well. Even My Document also can we move it to D. I will explain in the next post. Just wait yes …
2. Get used to backup data regularly to another storage medium.
For archives and important data, it helps us also make backups to CD / DVD or to another storage such as external hard drive. So when something happens to our computers, important data will not be lost because it was stored in a safe place.
3. Be careful and note that the data will be removed when doing disk cleanup.
Let us not regret it later because the deleted data is data that is still needed.
4. Complete computer protection from virus attacks, Trojans, Spyware and others.
Moreover, if the Internet connected computer. This can be done by using software-software that can be downloaded for free on the Internet, for example AVG, Spybot, etc..
Better to prevent than cure. If the behavior in using our computers correctly, guaranteed you will not regret in the future because of loss of important data. Good luck.
