SD card is the abbreviation of Secure Digital Memory Card. Due to its small volume, fast data transmission speed, large storage capacity and high security property, SD card is widely used in various kinds of portable mobile devices, such as digital camera, multimedia player, and mobile phones. However, in SD card use, we often need to delete files stored in SD card for some reasons, which is the situation encountered by every SD card user. It is very unfortunate that we delete some important files because of our careless operation when we are deleting files stored in SD card. Since the misfortune has happened, we have to accept it and try our best to reduce losses caused by it. And the best method is to recover deleted files from SD card. 

Users who have much experience of data recovery may know that we should connect SD card to computer first and then use data recovery software supporting SD card recovery to recover deleted files from SD card. This process seems to be easy, but it is difficult in practical operation. As different SD cards may have different file systems, we need to choose data recovery software which supports multiple kinds of common file systems to recover deleted files from SD card. Nevertheless, in this era overflowing with data recovery software, it is not easy to find some software which not only supports SD card but also supports diverse common file systems. Here, the professional free data recovery software, MiniTool Power Data Recovery, with powerful functions is recommended. This free data recovery software is in support of various storage devices including SD card as well as multiple operating systems and file systems. For detailed information, please visit its official website http://www.powerdatarecovery.com/. 

Since MiniTool Power Data Recovery has excellent compatibility with varying mobile storage devices including SD card, it is easy to recover deleted files from SD card with this free data recovery software. Run the software and its simple and utility interface will be shown. 

In the main interface, five function modules designed for different data recovery situations are provided. To recover deleted files from SD card, we should click "Undelete Recovery" and the following interface will appear. 

In this interface, select the partition standing for SD card (since the operation of SD card files recovery and hard disk partition data recovery are same, we'll take Partition H: for example), and then click "Recover". The following picture will be shown. 

In this interface, all files in the partition are listed after the free data recovery software finishes scanning the selected partition. Files marked with red crosses are deleted files. Find and check the deleted files that will be recovered and then click "Save Files" to store the recovered files to a safe location. Now, we have finished all operation of recovering deleted files from SD card. 

In different computer age, we have different disk management methods. In DOS era, all disk management and the majority operations are realized with DOS command. For common users, it is every difficult to realize all-sided disk management with DOS command. The reasons are as follows: firstly, common users are unfamiliar with DOS command; secondly, disk management of DOS command is not all-sided. However, since Microsoft released Windows 95 which is a visual operating system, disk management mode has become diversified. Originally, we can perform more completed disk management with Windows built-in disk management tool. Nowadays, with the continuous development of software technology, the third party partition magic can help us realize all-sided disk management. Among these kinds of partition magic, MiniTool Partition Wizard is an outstanding performer. 

Of course, besides DOS and Windows operating system, there is another operating system namely Unix which realizes various kinds of operations by inputting corresponding command. For those users who are familiar with Unix, it is an excellent operating system. But for these users who are unfamiliar with command, it is difficult to perform disk management under Unix.
After hearing the above introduction, some friends may ask curiously whether there is a method for managing disk partition in DOS, Windows and Linux Unix2. For this problem, MiniTool Solution Ltd. gives us a clear answer.

No matter what kind of operating system you use, a new disk management mode has appeared. MiniTool Solution Ltd., a professional Canadian software development corporation, has renewed its excellent partition magic MiniTool Partition Wizard successfully. This partition magic provides different management modes aimed at different operating systems. With it, we can manage disk partition in DOS, Windows and Linux Unix2 easily and safely. Besides, even though we can not boot the operating system, MiniTool Partition Wizard Bootable CD can manage disk partition without entering the operating system. Therefore, MiniTool Partition Wizard can help us manage disk partition completely. The following interface is the disk management interface of MiniTool Partition Wizard Bootable CD. 

When we fail to boot the operating system, we can put MiniTool Partition Wizard Bootable CD in the CD-ROM to boot the computer. Once the computer read the CD, the above interface will appear. Here, select "Boot from Partition Wizard Boot Disc" to enter the next interface: 

In the above interface, select an appropriate resolution, and then click "Enter" to go to the following management interface: 

After entering the above interface, we can manage disk partition. This interface shows us numerous partition management operations of MiniTool Partition Wizard Bootable CD. If we can not reboot the computer because of system partition loss, the function "Partition Recovery Wizard" can help us recover lost system partition. Then, set it as an active partition with "Set Active" function, and the lost system partition is recovered successfully. As a result, we can boot the computer. 

No one wants to see data loss happening to him. But it is inevitable in daily computer use, because various situations will cause data loss, such as virus attack, accidental deletion, and accidentally formatting. We should figure out a solution to reducing the losses to minimum. The only way is to recover lost data. But finding a suitable data recovery software is difficult for most computer users. At this time, Stellar Phoenix Windows Data Recover can help you a lot. It is a data recovery software that runs in Windows operating systems. With this software, users can realize recovering lost data caused by accidental deletion, disk formatting, virus attack, and so on. It is a piece of rather great data recovery software. 

Meanwhile, MiniTool Power Data Recovery, which has the same type with Stellar Phoenix Windows Data Recover, is an outstanding performer among all data recovery software, too. It is developed by famous software company – MiniTool Solution Ltd., and has more powerful data recovery capability. MiniTool Power Data Recovery can also realize data recovery operations that Stellar Phoenix Windows Data Recover does. The operation is much simpler and more convenient. You can get information about functions of MiniTool Power Data Recovery from its main interface. 

This is the main interface of MiniTool Power Data Recovery. Compared with other kinds of data recovery software, MiniTool Power Data Recovery has more user-friendly and clearer design of interfaces. Users can choose from the five functional modules according to specific situations of data loss. "Undelete Recovery" functional module is for recovering accidentally deleted data. 

"Damaged Partition Recovery" realizes recovering lost data from formatted partition or caused by virus attack. "Lost Partition Recovery" helps users recover data from lost partition. "Digital Media Recovery" recovers media files quickly. "CD/DVD Recovery" helps users access CD/DVD that can't be read by computer CD-ROM. From the interface design, we can see MiniTool Power Data Recovery has the finest design among numerous kinds of data recovery software. 

Not only the interface design of MiniTool Power Data Recovery is excellent, it still has many other features that are better than other software, especially its data recovery performance. MiniTool Power Data Recovery realizes scanning lost data fast. I believe most of you know that most kinds of data recovery software scan the whole disk for lost data. 

And users have to find out the files they want to recover among the results. It is rather troublesome. Nevertheless, MiniTool Power Data Recovery is different. It scans partition, and the scanning range is smaller. So it scans faster and more conveniently. What's more, MiniTool Power Data Recovery still has filtering function. It finds data and files which need recovering quickly among a large amount of data. That's why MiniTool Power Data Recovery can recover lost data in quickly.

RAID is short for Redundant Array of Independent Disk, and it is a technology which can provide higher storage performance and data backup competence than a single hard disk by combining multiple independent hard disks (physical hard disk) in a hard disk group (logical disk) in different ways. RAID has many advantages, such as high-speed, high-capacity, safety, and reliability. Besides, it realizes fault tolerance, and it is an intellectualized disk collection with higher fault tolerance competence, higher security, and higher reliability. As a mass memorizer in the modern network system, RAID is widely used in disk server and becomes an indispensable storage device of the solution of high reliability network system, thereby making network system save data reliably and system run normally. 

To promote the safety of system, we must ensure data security first, because every user will store personal data in computer or server. Especially for large enterprise, server data security must be ensured. However, as long as personal computer or server exists on the network, data are in potential safety hazard. Any operating system is not perfect, and it becomes safer after unceasing upgrade. Of course, antivirus program can effectively prevent virus from invading operating system to damage file, but operating system and antivirus program can not ensure data security. On the network, hacker brings more serious influence. Nowadays, hackers do not fear how safe our system or server is or how powerful the functions of antivirus program are, because they can bypass our multiple defense and enter personal computer or server directly to damage data or even system, which may make personal computer or server unable to run normally. If the server of a large enterprise is unable to run, this enterprise will bear heavy losses and serious damage. 

If the operating system is damaged, we can reinstall an operating system to solve the problem. However, can we install damaged data after data damage happens? It is of course not. Certainly, backing up data ahead of time is an effective solution to protecting data, because we can use the backup to restore original data after original data are damaged. Nevertheless, it is difficult to accomplish server data backup successfully since server stores a large number of data. Therefore, we had better use MiniTool Partition Wizard to back up server data. No matter how many data are stored on server, we also can use this partition manager to back up server partition or back up the whole server disk, saving a large amount of time and ensuring data security effectively. After running this partition manager, we will see the following interface: 

This is the main interface of this partition manager. Here, select the partition needing to be backed up. Then, click "Copy" button on the tool bar to enter the next interface: 

Next, select one unallocated space and click "Next" button. 

Then, we can resize the partition used to store data backup by dragging the right triangle in this interface. Next, click "Finish" to go back to the main interface: 

In the main interface, we can see a partition without drive letter, and this partition stores data backup. At last, we need to click "Apply" to perform needed operations. After that, we are successful to back up data.
