Possibly the worst thing that can happen to your computer is to get your hard drive erased. As a result you could lose all your photos from vacations, your music, movies, your text files, business files, and everything else.
The hard drive can be damaged in many ways; it can be physically damaged, the software can be damaged or it can be affected by a virus. You should protect your hard drives and deal with them with care. There is a possibility of damaging the hard drive by exposing it to extreme temperature changes, for example when you are taking the hard drive out of your computer and putting it in another you may turn on the computer when the drive is still cold. This process could damage it or even erase all data on it.
Viruses can erase your hard drive so you should use some Anti-Virus protection. Have it installed on your personal computer in order to take some risks away. There are Trojan horses, which are a specific type of virus that appear in forms of downloadable games, applications or even screensavers, and when you install any of these, it erases the complete drive and destroys all the data on it.
There are some programs that can help you recover your lost data. There is a variety of software that can help you and there are many applications that are good, but these things do not always solve the problem itself.
There are people who fix damaged hard drives and recover the missing data. But those services are can be expensive. If you have some important data related to your business, precious photo's or other important files on your computer however, it can definitely be worth it to make use of such a service.
There are some things that you can do to try to get your hard drive's data back. People actually freeze their hard drives by putting them in refrigerators, this actually can help to recover the data but the possibility is low and you could destroy your hard drive permanently.
The hard drive is hardware that is surely the most important component in one's personal computer tower. People suffer most if their hard drives are erased which is logical. Imagine gathering information for months or even years and in one moment you lose all of it. You should pay attention and use the right protection to prevent this catastrophe from happening.
The worst case scenario with hard drives is when you work on your computer and store all your business data on it. Hard drives can stop working without any damage done to them. So the best and wisest thing for you to do if you work on a computer is to store all your data on another drive as a backup as well, or even transfer backups to some multimedia, like CDs, DVDs, USBs, etc.
There is a big number of cases where people lost all of their data data so try to pay attention on how you reserve it.
