Nowadays, with increased storage capacity available to everyone, data is being stored at an alarming rate. Even the average computer user has more than 1TB (terabyte) of data if they like to store home movies or family photos, like the average person does.

When this precious data is lost, it is nice to know what could have caused it and maybe next time we can avoid this problem.

1. Hardware Failure

Of course this cause for data loss is a nightmare as you have no control over it. For example if your hard drive fails from the internal ball bearings being worn out, you cannot help this. A hard drive is a mere mechanical device that has working parts. This means that things can go wrong.

2. Human error

Hey, we are all human after all and many of us delete files accidentally. In fact humans do a lot of stupid things that can cause data loss. You might spill a drink on your computer and blow up the whole thing, or maybe you might think you have saved files, when actually you haven’t.

3. Software corruption or problem

When a computer user installs software and then restarts the computer, something goes wrong, and your Windows will not start at all. You know you have done something to cause an error. The problem here is that people don’t know how to get out of this situation and prevent data loss. They actually try so many troubleshooting tasks that it sends the computer into a more serious error.

4. Computer viruses

Computer viruses can be vicious and destroy your files very quickly. They can cause data loss and sometimes, if you’re lucky, access to your files. If you have only lost access to your files then maybe you haven’t actually lost your data yet. But if the virus has infected your files, your data may be now useless and corrupted.

5. Disaster

Unfortunately we have no control over a disaster that might happen to your computer. This cannot be blamed on anyone in particular, but it is devastating to experience this data loss nevertheless.

Water damage may be repairable in some cases, as long as the computer was not operating at the time. Many computer professionals remove dust from computers by hosing the entire system out with water. Obviously there is no power connected to the computer, and when dried out correctly, the computer works as it did before.

I still recommend hiring a professional to recover your data, as sometimes it is too precious to lose.

How to Prevent Data Loss

Some things we just have no control over, so therefore we cannot prevent data loss. But we can prepare for data loss by implementing a backup data and recovery plan. You can also maintain your computer carefully and keep it running smoothly.
