Most users think data will disappear thoroughly once they empty the recycle bin after deleting data. Actually, they are wrong. Users who know something about the principle of data storage know the commonly used deleting and formatting can not delete data from the disk thoroughly but mark a special mark which makes the system unable to recognize these data. Therefore, some users mistakenly think data have been wiped thoroughly. As a matter of fact, for these kinds of deleted data, we can recover them easily as long as they are not overwritten or damaged, and there are many recovery methods. Later, I will introduce these methods. But before introducing them, let me introduce some methods for deleting data thoroughly. 

After knowing that deleted data can be recovered, some users may worry about the leakage of privacy included in deleted data. Well then, how to wipe data thoroughly from hard disk? To solve this problem, we need a technology called Erase with which we can erase a hard drive repeatedly and wipe original data thoroughly. Then, even high-efficiency data recovery methods can not recover these data. However, Erase was mainly used in military institution, political institution and other important institutions before. Fortunately, with the unceasing development of software industry, this technology has been applied to partition management software. For example, the "Wipe" function of MiniTool Partition Wizard is used to erase a hard drive repeatedly, ensuring the safety of deleted data. Next, let's go back to the first topic: how to recover deleted data. 

We have talked that data deleted with common deleting operations can be recovered. Well, how to recover deleted data? For these users who require extremely high computer operability or users who have a basic understanding to data storage principle, they can recover deleted data by altering file information table when facing simple deletion. User can get relevant information about this method from the internet. However, it is difficult and risky for common users to adopt this method. If users operate mistakenly, deleted data may be damaged again or other data may be lost. Therefore, this method is not recommended to common users. Today, data recovery software is advised to recover deleted data, but not every piece of data recovery software is recommended. As the current software industry is not very normative, there is much inferior software on the market. If we use inferior data recovery software carelessly, more serious data loss may happen, bringing greater losses. Therefore, users should pay much attention to safety when selecting data recovery software. Furthermore, utility is a key factor we should care about. I believe nobody is willing to download a piece of useless data recovery software with costing a large amount of time. Considering these aspects, I strongly recommend MiniTool Power Data Recovery. 

MiniTool Power Data Recovery can realize multiple kinds of data recovery (of course, if we erase a hard drive to wipe data, these data can not be recovered). For example, this data recovery software can perfectly recover lost data caused by simple deleting, formatting, virus attack, and partition loss. To recover lost data with this free data recovery software, we should visit its official websitehttp://www.powerdatarecovery.com/ to download it first. Then, install and run it: 

In the main interface, "Undelete Recovery" module is specially used to recover deleted data. Users just need to click this functional module, and then select the partition where lost data are. Then, click "Recover" to look for deleted data. Next, please check the files which need recovering. Next, click "Save Files" to accomplish deleted data recovery. 

Presently, all the disk manufacturers have produced 4K disk, and the traditional disk of 512 sector size has gradually been replaced by the new 4K disk. Compared with traditional disk, what kind of advantage 4K disk has? Next, let me introduce some details about 4K disk to you.

As its name implies, sector size of 4K disk is expanded from traditional 512B to 4096B. This change promotes disk performance and improve disk space usage rate. As we all know that sectors in disk are not adjacent. Between sectors, there are Gap, ECC, Sync, Address Mark, and data, etc. A disk with large capacity will be divided into so many sectors if the sector size is 512B, and the gaps between will become a great many, too. Therefore, much space is wasted. Employing 4096B sector size, disk space usage rate is greatly improved, because the space occupying proportion of gaps is reduced.

Even though the advantage of 4K disk is attractive, 4K disk technology is still in a transition period. We need to pay attention to that not all the operating systems can identify 4K disk. In Windows operating system, only Windows Vista Service Pack 1 and later Windows versions can identify 4K disk. 4K disk manage tools are also very few. Fortunately, now we have a perfect choice – MiniTool Partition Wizard, the magical 4K disk manage tool. This 4K disk manage tool possesses powerful partition management functions, realizing perfect traditional disk and partition management, as well as 4K disk management according to the developing tendency. Next, let me show you an operating demonstration of creating partition in 4K disk for your better understanding.

At first, we need to visit http://www.partitionwizard.com/ to download MiniTool Partition Wizard. The following picture shows the 4K disk information:

Select the 4K disk, and click on "Properties" button to check properties of this disk. We can find the sector size of 4K disk is 4096B. Next, let's create partition with 4K disk manage tool.
Select the unallocated space, and click on "Create" button:

In this interface, we can set properties of new partition, such as file system, drive letter, partition label, partition size, and set primary or logical.

Here, we can find that there is a newly created partition in 4K disk. Click "Apply" button to execute operation.
