However, it often occurs that the data get lost in the USB flash drive. It is important to determine what causes the data loss and then uses the right way to get the data recovered.

The Situations for Data Loss on the USB Flash Drive

There are many reasons causing the data loss on the USB drive.

Situation 1. When the U disk is being read or written, the U disk is pulled out.

Situation 2. When the U disk is read or written, the computer has no power or turns blue screen or encounters abnormal shutdown.

Situation 3. Accidentally delete the files in the USB drive. The difference from the file deletion in the hard disk is that when the data from the USB drive is deleted and it can not be found in the recycle bin.

How to Prevent Data Loss on the USB Flash Drive

Those are the situations of data loss for the USB drive. We should pay attention to the above situations when using the USB drive, so as to avoid data loss many times.

First of all, for the quality problems of the USB drive itself, we can solve it by means of prevention. For example, we should first confirm whether it works and whether it is an expandable USB drive, so as to avoid data loss to the utmost extent. Especially for the expandable USB drive, the capacity is larger than the actual size so the copied data cannot be copied again as it is in the virtual capacity.

For the situation 1 and 2 as listed above, including mistakenly ejecting the USB drive or computer’s problems, we should also do something to prevent them.

a. When the USB drive is plugged into the computer, do not touch the USB device anymore, and make sure the computer will not accidentally power off. If the USB drive is being improperly used and cannot be read, you can use the system’s function to help detect and repair, by right-clicking the USB drive, then you can choose Tools in the Property option. Then you can use the error check tool to start the process.

b. If you frequently insert and pulls the USB drive improperly and it does not safely eject, it is easy to cause data loss. So, how to use and safely eject the USB drive? Just follow the methods below.

Method 1:

After the USB drive is used, you need to close the files on the USB drive. Then right click on the USB drive icon in the task bar, choose to eject it. If it does not remove, you will need to try the following.

(1) Check if there are programs in the computer that occupy the resources of the USB flash drive, such as music, video player or other software installed in the USB flash drive.

(2) Check if there is a virus in the  USB drive, which causes the system resources to be occupied. It is recommended to use anti-virus software to specify the USB drive path and perform a full scan to remove the impact of the virus on the USB drive.

Method 2:

Insert the USB flash drive, then select “My Computer” → “Properties” → “Hardware” → Device Manager → “Disk Drive”, find the USB drive project, open the “Properties” dialog box of the USB flash drive. Switch to the “Policy” tab, select the “Optimize for quick delete” button, and click “OK”. In this way, when the U disk is used next time, as long as the data operation is completed, the U disk can be directly pulled out from the computer.

After understanding the two methods of safely unmounting the USB flash drive, everyone can safely eject the USB flash drive, and the data loss can be effectively avoided.
