External hard drive is a portable external memory device used for exchanging high-capacity data among computers. Main uses are as follows:
1. Add more storage space when disks are read-in.
2. Save some important but not commonly used data.
3. Do back-up for our data so as to avoid costing much time in recovering data when original files are lost. Costing much time may bring inconvenience for our life and work.
4. Can be used as medium for data transmission, with which we can take a large amount of data transmission.

From the above information, we know external hard drive is mainly related to some important data we need. It is important to protect hard disk from being damaged if we want to take good protection for these data. But how can we protect hard disk? To know how to protect hard disk, we must know what problems hard disk may emerge. The following aspects are analysis to problems hard disk may emerge:
1. External hard drive may be damaged in wet and other bad conditions, leading to big loss of data.
2. Partition in hard disk may be lost when power is suddenly off, which is also harmful to hard disk.
3. Hard disk structure may be damaged when external hard drive is in high-temperature and high-pressure conditions.

The above are just several situations where m external hard drive may emerge problems. If we pay attention to these situations when using it, we can avoid losing data. But there are some exceptions. For example, data or partitions are lost when using external hard disk drive due to virus attacks. Setting another example, data are mistakenly deleted or disk partition structure is damaged by software when using it, which can lead to partition loss or unable visiting. Under these circumstances, how can we protect our data? Now, we can recover our lost data with MiniTool Power Data Recovery. But how can we recover these lost and damaged partitions? Users can use MiniTool Partition Wizard.

Why choose MiniTool Partition Wizard

4. Can change the size of cluster better, which will not lead to losing data and can play performance better.
5. Can merge partitions safely; adjust partition size and other high-level disk managements.

All that functions are just a small part of functions of MiniTool Partition Wizard. If users want to know more functions about this software, you can visit its official website. In order to make everyone learn operation process of MiniTool Partition Wizard better, I will demonstrate how to recover external hard disk drive lost data with MiniTool Partition Wizard.
