Caution: your data may be stolen by other people
Now, problems of data security become more and more serious, which almost exists in every computer. At present, the main factors which threat computer data are displayed below:
1. Data loss, system crash and other results caused by users’ accidental operations.
2. Data damage caused by malicious programs such as virus.
Normally, if we pay more attention to suggestions above, we can prevent some data from being leaked or stolen. Data loss always brings inconvenience to our life, for example, leaking privacy or confidential file from resold hard disk. Users will be very upset once encountering these situations.
Great risks exist in resold hard disk data. When we resell hard disk to other people, we must be cautious. If evil people want to steal our data, they can make it even through we delete all the data or format all hard disk partitions. At this time they will use data recovery software to find data back. For instance, the professional data recovery software, MiniTool Power Data Recovery, can find data back to achieve their purpose. If we encounter this situation, privacy will be perhaps stolen by other people. What’s more worse, we may expose information of our company to competitor, so we must ensure data security.
As a matter of fact, it is very simple to ensure data security on hard disk. Before we resell hard disk, we must thoroughly wipe hard disk data. But how can we do it? There are two means, one is to use low-level formatting; the other is to thoroughly wipe data with partition administrator. The former can thoroughly wipe data in every sector of hard disk. Once the data is wiped from hard disk, it will never risk being recovered. But what is worth noticing is that this low-level formatting is wastage operation, which has negative influence on service life of hard disk, and this operation costs much time. So I don’t advise you to use this method to wipe data thoroughly. And then the second method is to thoroughly wipe data with server partition magic. MiniTool Partition Wizard is a professional partition manager. By using its Wipe Partition we can thoroughly wipe data on partition, thereby leaving no chance for data recovery software to recover data. Its powerful wiping partition method is similar to the theory of method used by US military to destroy data information. After using this method to manage hard disk, we don’t need to worry its influence on hard disk lifetime. It doesn’t cost us much time to wipe and prevents privacy and confidential files from being leaked. It can be said that data is thoroughly wiped by MiniTool Partition Wizard.
The potential data security risks from reselling hard disk are solved. But how can the hard disk data become safer? We just need to do things below to protect data in hard disk.
1. Install anti-virus software and upgrade it in time. Because virus attacks may cause data loss in hard disk, we should regularly kill virus to reduce virus threat to data to lowest.
2. Back up important data files. A storm may arise from a clear sky. Your data may be lost when power off. So regularly backing up data is a good habit.
3. Don’t frequently visit irregular websites, most of which may mount Trojan. Once we visit them, Trojan will come along to cause program files deficiency. So we’d better not open unknown website at will.
4. Too high computer temperature will lead to equipment failure, so please pay attention to computer heat dissipation when using computer. Remember to turn off the computer when it is overheated to prevent data loss due to equipment failure.
If we follow the points above, our computer data is more secure. And when you encounter the unfortunate situation, data loss, do not worry. If hardware failure gives rise to data loss, we need to turn to data recovery professional. As for data loss caused by non-hardware failure, we can use MiniTool Power Data Recovery to recover data by ourselves.
