A USB flash drive, also known as a USB flash drive, is a portable storage device that is widely used in modern life and work. Due to its small size, large capacity, fast transfer speed and other characteristics, USB flash drive has become an important tool for us to store and transfer files in our daily life. However, the accidental deletion of USB flash drive files is a common fault that may bring us a lot of trouble. The following will analyze the causes and solutions of USB flash drive files by mistake.
Q: Can I get back the USB flash drive file if it is deleted?
A: It can be retrievedThe reason why USB flash drive files can be recovered after deletion is that the storage space of USB flash drive is composed of multiple sectors, and these sectors are small storage spaces. When we store files to a USB stick, the files take up these spaces. And when we delete a file, it's not really a complete deletion, it's just that the space is marked as free by the system. Only when we deposit new data into it again will the previously deleted part of the file be occupied and overwritten. Therefore, as long as you do it in time, you will have a chance to recover deleted files from USB flash drive. Of course, stopping the write operation in time is also a prerequisite for restoring the data of the USB flash drive.
1. There may be nine reasons for the accidental deletion of USB flash drive files:
Human misoperation: When using the USB flash drive, users may click the delete button by mistake due to negligence or unfamiliar operation, resulting in the accidental deletion of important files.
Virus infection: Malicious viruses or malware may invade the USB flash drive and maliciously delete or hide files, resulting in file loss.
File system error: The file system of the USB flash drive is incorrect or corrupted, which may cause the file to fail to be read properly or deleted by the system.
Abnormal unplugging: If a user suddenly pulls out the USB flash drive during file transfer or writing, the file may be damaged or deleted by the system.
Computer system problems: The computer system is abnormal or crashed, which may lead to the deletion of files in the USB flash drive connected to it.
Unsafe ejection: When the file transfer is not completed, the user directly performs the "safe ejection" operation, which may cause the file transfer to be interrupted, resulting in the loss or accidental deletion of the file.
Physical damage to the USB flash drive: The memory chip or circuit of the USB flash drive is physically damaged, which may cause the data stored in the USB flash drive to fail to be read normally or be deleted by the system by mistake.
Format error: If you select the wrong file system or make a mistake when formatting the USB flash drive, the data of the entire USB flash drive may be cleared or deleted by mistake.
Insufficient storage space: If you try to copy large files to the USB flash drive, some files may be deleted by the system to free up space.
All these reasons may lead to the accidental deletion of files in the USB flash drive, so users need to be vigilant and take corresponding precautions to reduce the risk of accidental deletion of files when using the USB flash drive.
2. The solution to the accidental deletion of U disk files and the need to retain the files.
1: Immediately stop using the USB flash drive: If you find that a file is deleted by mistake, you should immediately stop using the USB flash drive to prevent the data from being overwritten.
2: Find backup: Check whether there is a backup of the file, and if there is a backup, you can restore the accidentally deleted file from the backup.
3: Use data recovery software: Use professional data search software to try to retrieve the files that were deleted by mistake. The steps to recover USB flash drive files from accidental deletion are as follows:
3. If you do not need to keep the file after the USB flash drive file is deleted by mistake, you can take the following methods:
Format USB flash drive: Directly format USB flash drive to completely erase all files, including those that have been deleted by mistake.
Low-level formatting: Use a low-level formatting tool to perform a deep erasure of the USB flash drive to ensure that the files cannot be recovered.
Reset the USB flash drive: Use the built-in reset function of the USB flash drive to restore the USB flash drive to its factory state and delete all files.
Chip-level destruction: Professional equipment is used to destroy the memory chip of the USB flash drive to ensure that the data is completely erased and cannot be recovered.
Physical damage: Damage the USB flash drive by physical means, such as smashing or dismantling, so that it cannot be used again to ensure that the files will not be leaked.
Data overwriting: Write a large amount of irrelevant data to the USB flash drive to overwrite the original accidentally deleted files, making them unable to be recovered.
Please note that the above methods are destructive, so please confirm that you do not need to keep the files before proceeding. If there is important data in the USB flash drive, we recommend that you back it up before performing the operation. At the same time, for the USB flash drive that is no longer needed, you can choose to dispose of it in an environmentally friendly way to protect the environment.
4. The methods to use the USB flash drive correctly and avoid data loss caused by accidental deletion of USB flash drive files include:
Regularly back up USB flash drive files: Back up important files in USB flash drive frequently to prevent data loss caused by accidental deletion of USB flash drive files.
Pay attention to file operations: When using the USB flash drive, you should be careful to perform file operations to avoid accidentally selecting and deleting important files to prevent the USB flash drive files from being deleted by mistake.
Secure ejection of USB flash drive: Before pulling out the USB flash drive, be sure to use the "secure ejection" function provided by the system to ensure that the file transfer is completed to avoid file corruption and accidental deletion of USB flash drive files.
Prevent virus infection: Regularly scan the USB flash drive with reliable security software to detect and remove possible viruses and avoid accidental deletion of USB flash drive files caused by malware.
Avoid editing files directly on the USB flash drive: Try to copy the files to the computer for editing to reduce the risk of accidental deletion of USB flash drive files.
Pay attention to the physical protection of the USB flash drive: Avoid physical damage to the USB flash drive, such as dropping, water shower, etc., to reduce the risk of accidental deletion of USB flash drive files caused by physical damage.
Following the above suggestions, using USB flash drive correctly and strengthening data protection awareness will help reduce the risk of accidental deletion and data loss of USB flash drive files. In the event of accidental deletion, it is also important to take timely measures to recover the data.
5. Summarize the accidental deletion of USB flash drive files.
Through a detailed analysis of the reasons for the accidental deletion of USB flash drive files, we can find that in many cases, the accidental deletion of files can be avoided. Proper use of USB flash drives, regular data backup, vigilance and corresponding precautions are the keys to reducing the risk of accidental deletion of files. If you are unfortunate enough to experience accidental deletion of files, please choose an appropriate solution to try to recover data or dispose of the affected USB flash drive according to the specific situation.
