With the constant development of Flash chip storage technology, U disk has become the classical invention of this age. Since its birth, U disk has won much popularity because of its portability and availability. From several MB to dozens of GB, from USB1.1 port to USB3.0 port, U disk is developing towards the direction of monopoly position of mobile storage market. However, U disk is still in risk of data loss while it brings us convenience and high efficiency.

Causes and solutions to data loss in U disk:

1.       Artificially accidental operation

This is the most common cause of U disk data loss. Accidental deletion and accidental formatting are both the main causes of data loss. Encountering such a situation, we can use professional data recovery software to restore lost data. MiniTool Power Data Recovery is such a kind of excellent data recovery software. What's more, it is free.

2.       Virus attack

This cause is rather frustrating. Virus will probably cause data loss or damage. When U disk is infected with virus, we should firstly kill the virus. Common anti-virus software is able to kill the U disk virus. After killing the virus, we can also use MiniTool Power Data Recovery to recover lost data. 

3. Hardware fault

Hardware fault will lead to data being lost thoroughly. At present, there is no good solution to this situation. You can ask professional data recovery companies for help. But they still cannot guarantee 100% data recovery rate. Therefore, for this situation, we should do preventing measures firstly. Backing up important data in time is the best solution.

As U disk is portable device, preventing data loss in U disk from software and hardware is not enough. We should do good daily management.

1. Buy U disk with guaranteed quality. Because the making technology of U disk is simple, there are many U disks which are with poor quality in the market. These kinds of U disk will bring us terrible losses.

2. Use, plug, and unplug U disk in correct ways. Do not unplug U disk when the indicating light is still shining, because it means U disk is still accessing or writing data. Unplugging it at that time will lead to data or hardware damage.

3. When system prompts "The mobile storage device cannot be stopped now", do not unplug the U disk, because the U disk is still working and forcible unplugging will cause data loss. You can wait for a moment and then try to unplug it.

4. Do not put U disk in moist environment for a long time, because it will cause the surface of U disk to oxidize and the sensitivity of port will be decreased.

5. Do not keep U disk plugging to USB port for a long time, because it will cause the port ageing, and computer will be unable to identify U disk.

As the most popular file system, NTFS already becomes the standard file system under Windows, even many Mac users use NTFS file system. The reason why MTFS has such high use rate is that it provides users with higher stability, security and applicability. Data loss is always difficult to solve, NTFS data loss also frequently occurs due to various accidents or malicious attacks. Luckily, we have third-party NTFS data recovery tool. 

Choose suitable NTFS data recovery tool Lots of NTFS data recovery tool exists on the current market, but they can only perform data recovery for deleted data and seldom perform data recovery for damaged or lost partition. In order to solve various data recovery problems, the best data recovery software launched by MiniTool Solution Ltd. is highly recommended. MiniTool Solution Ltd. launches two pieces of data recovery software for us – MiniTool Power Data Recovery for Windows and MiniTool Mac Data Recovery for Mac platform. The functions of these two pieces of software are basically similar, and can solve various data recovery problems.

This is the main interface of data recovery software MiniTool Power Data Recovery, which is similar with and the main interface of data recovery software MiniTool Mac Data Recovery ( MiniTool Mac Data Recovery has no "CD/DVD Recovery" data recovery module). which contains five data recovery modules - Undelete Recovery, Damaged Partition Recovery, Lost Partition Recovery, Digital Media Recovery, CD & DVD Recovery.

For common computer users, the biggest trouble is that computer cannot start. Most users will feel frustrated about this. They mostly try to reinstall the operating system to solve the problem. But this method cannot keep the security and completeness of data in computer, so it is not the best solution to solve the problem. Here let me introduce some good solutions to you.

Firstly, we should stay calm when facing this situation. Don't panic. Otherwise, you will cause more terrible data loss. You should analyze the causes according to the prompts when booting computer. The most common one is "Operation System not Found". This means your system partition is lost, so you cannot access it.

As to this situation, most users will try to use a data recovery software to restore system partition. But actually, data recovery software cannot restore system partition directly, because we have to enter operating system. Some kinds of data recovery boot disk in the market can only recover lost data in lost partition but unable to restore partition and recover data at the same time. Even though we have recovered all system files to other partitions or storage devices, we still can't boot the system normally.

It is because we can only boot the system by visiting the system files in active partition. But data recovery software cannot help us set active partition. At this time, we can use a professional partition boot CD to create an active partition in the computer and then we can move all system files to that partition. The whole process is rather complex, and moving system files is in risk. This is not a good solution.

Now, let me introduce a fast and convenient solution. That is using a partition boot CD that has function of recovering lost partition. Thus we can recover lost partition in time when partition loss occurs. And all the data in it will also be recovered completely. As long as system files are not lost or damaged before system partition loss, we can restore them quickly. Once I have used such a partition boot CD – MiniTool Partition Wizard Boot CD. You can search on the Internet for its detailed information. But I have to remind you that you must use the function of "Set Active" to set the system partition as active partition so that you can boot the operating system successfully.

Since I bought MAC, I have given up Windows operating systems. Nobody can resist the unique and noble style of MAC. When I just came into contact with MAC, I had fallen in love with it. Since I had been using Windows operating systems, I feel rather difficult when operating MAC. Occasionally, I may make a big mistake because of accidental operations. Yesterday, I have experienced a horrible data loss disaster.

Windows users know that when we save two files with the same file name to one location, system will prompt about the duplication of file name, and ask if we want to cover the existing file. Under this situation, if we click "Yes" button, the system will cover the original file with new file while other files will remain. This situation is quite common, so we don't feel anything wrong.

But yesterday, I lost a lot of my favorite pictures as a result of my habitual choice. The accident was very simple. When I was clearing up files in MAC disk, I found that two different partitions saved the same folder saving many my favorite pictures. I tried to merge them together. When I was trying to cut one folder to another, system prompted if I would like to replace the existing files having the same names, and I clicked "Yes" button without hesitation.

However, after executing, I opened the folder to check the pictures, but only to find the original files were disappeared. There were only files in the folder I just had cut from the other partition. I rather regret. I thought it was the partition fault that leaded to this data loss disaster, so I asked for help on the Internet.

Hearing my description of the situation, some users told me it was a common situation in MAC. It is because MAC platform is very different from Windows platform. When replacing files in MAC, system will replace the whole folder and delete the original folder. After knowing about this, I began to search for a solution to recover lost data. Someone told me that I could only ask professional data recovery companies for help, because finding a suitable and powerful MAC data recovery software is very hard. I once heard that data recovery companies charges users very high fees, but the lost pictures were not worth that money, so I gave up the solution.

I continued searching on the Internet for a best solution. One article that introduced methods for recovering lost MAC data attracted my attention. It suggested a MAC data recovery software named MiniTool Mac Data Recovery. The article said that it could easily recover lost data in MAC under various situations. I decided to try it. I visited the official website of MiniTool Mac Data Recovery, and downloaded it to my MAC. The official website also showed me various kinds of recovering presentation. At last, I successfully recovered my lost pictures. MiniTool Mac Data Recovery helped me a lot.

Have you ever experienced the situation of system being unable to be accessed as a result of sudden accident (such as virus attack and system crash)?

Unfortunately, this situation is rather bad. It means your system or even your disk is damaged. Most users will try to repartition the disk or reinstall operating system to solve this problem. However, no matter repartitioning the disk or reinstalling operating system, both of them will lead to a huge amount of data loss. It is extremely dangerous.

If your computer has not stored much important data, these two methods are very well for you. But if there is some important data in your computer, these solutions are inadvisable; because nothing can make up the lost data. Therefore, we need to analyze the situation in detail when system is not accessible.

The main reason why we cannot access the operating system is system partition damage, so we should firstly consider about the damage causes of system partition. There are multiple causes: firstly, system files in system partition are damaged or lost as a result of virus attack. Secondly, file system in system partition is damaged so that the whole partition cannot be identified by computer. Thirdly, the whole system partition is faulted. Are there any differences between the second one and third one? Yes. The second one means the file system is damaged, but the partition is still there (such as DBR damage). But the third one means the whole partition is damaged or lost.

Generally, if common partition is damaged because of file system damage, we only need to format it and rebuild file system to solve the problem. But if it is system partition damage, we should use a partition boot disk like MiniTool Partition Wizard Boot CD to repair the system partition so that we can access the operating system. If this method fails, the reason must be that system partition is seriously damaged. We should use MiniTool Power Data Recovery Boot Disk to recover important data from system partition and save them to other partitions or external storage devices. Then we can reinstall the operating system.
