USB write protection problems: There are two common USB write protection problems, one is the USB drive itself has a write protection switch, and the other is that Windows will automatically set USB drives to read-only mode. The following solutions can help you solve these problems:
For USB drives with a write protection switch: If your USB flash restore files,usb controllers,broken usb drive file system,recover data
then the problem is the first port; if the device remains undetected, you have a faulty device. (Note that if you can’t reformat the USB drive , it will need replacing.) If there’s a problem with your new USB port, you’ll notice it thanks to either of these things: The device fails to be detected Your operating system displays an error message relating to the device (removing and replacing the device might solve this) Either way, you should investigate the state of the port. Has it been damaged in any way? The safest way to find out is to shut down your PC or laptop. Next, look at the USB device.

In the process of using USB flash drive, you will encounter various problems, such as can not read the disk, data loss, data distortion, what are the causes of these problems and how to solve them? As a professional USB flash drive manufacturer, in more than 10 years of production experience, the following questions are asked most often.
Q1： Why the U disk I bought is 16GB, But the actual capacity is not 16G when it is plugged into the computer?
Answer：
Because the bottom layer of the computer uses binary 1MB=1024KB. However, storage manufacturers use the
decimal system for convenience when making U disks, hard disks and other storage devices. So this difference is caused.
From GB to MB to KB to B to b. A total of 4 conversions are required. That is 1000/1024, which is 90.9%. In addition, the
U disk itself needs to make room for storing its own information and as a spare area, so the actual capacity of the U disk
is smaller than the nominal capacity of the U disk.
Q2： The actual capacity of the U disk should be reasonable ？
Answer：Comprehensive answer to question 1. Storage industry standard: The actual
capacity of the USB drive is not less than 90% of the nominal capacity is a qualified
product.
The actual capacity range of some common capacity USB drives is listed below.
1GB(900M-960M) 2GB(1860M-1960M) 4GB(3680M-3860M) 8GB(7680M-7800M)
16GB (14.4GB or more) 32GB (28.8GB or more) 64GB (57.6GB or more) 128GB (115.2GB or more)
The actual capacity is in brackets.
Q3： What are the file formats of U disk ？
Answer：
Generally speaking, there are three formats of USB flash drives, which are produced because of their different needs.
FAT, FAT32, exFAT.
Early USB disk capacity was small. It is in FAT16 format. Referred to as FAT format. Now USB drives of 2GB and below are in this format.
As the file size becomes larger, some individual files exceed 2GB in size. The FAT format of this type of file is not supported, sothe FAT32 format appears. Now 4GB-32GB U disks are in this format;
Subsequently, a single file with a size of more than 4GB appeared. This type of file FAT32 format is not supported. So the FAT64 format, or exFAT for short, appeared. Now 64G and above U disks are in this format;
A small-capacity USB drive can be made into a large format, such as 16GB can also be made into an exFAT format, which will not have a significant impact on the use of the USB drive. This solution can be used to store a single file of more than 4GB. Conversely, a large-capacity U disk can also be made into a small format, but when the file size exceeds the standard, the corresponding file cannot be stored.
In addition, U disk can be made into NTFS hard disk format and CDFS disc format when encountering some special situations.
Q4： I ob
viously bought a brand new empty USB drive, why is there a small amount of space in it being used, The formatting can’t be processed, is it a virus?
Answer ：FAT32 and exFAT format U disks require a small amount of space to store some information on the U disk itself.Of course, the occupied space has a certain range. If it exceeds this range, be careful about whether there is a virus, and you can perform anti-virus formatting. The standards are as follows;
2GB or less: FAT format, occupying space 0 bytes
4GB-32GB: ie FAT32 format, occupying space 4KB-32KB
64GB and above: ExFAT format, 384KB and above (no more than 1MB)
Q5： Why did I buy a 128GB U disk, It can’t be opened on my XP computer, but it can be used normally on my friend’s W7 system?
Answer ：The 128GB U disk is in exFAT format, which was developed later; and XP is an older operating system. ExFAT format is not supported in the early version and the GHOST version with reduced function that is popular on the Internet.
But it doesn’t matter, you can download an exFAT patch package for XP system online. It can be solved by installing it on the computer. The patch package is small and easy to find.
Q6： Can the USB flash drive name of the flash drive be changed at will?
The name of the U disk without write protection can be changed freely, but there are the following restrictions:
The length of the drive letter name cannot exceed 11 characters (1 Chinese character counts as 2 characters, and spaces are also counted as characters),Some characters that are too special should not appear and the computer cannot recognize them.
Q7： Will the flash drive be broken if dropped on the ground?
Answer ：
As we all know, the vibration caused by the mechanical hard disk falling on the ground can easily damage the precision parts inside and cause the hard disk to be damaged.
The U disk is different. It uses FLASH storage and has no precision parts.Therefore, under normal circumstances, dropping will not have any effect on the function of the U disk.
As for the shell of the flash drive, except for fragile shells (such as glass), the shell of the USB flash drive should not fall apart or break if it falls within one meter. It is inevitable that it will be scratched.
Packing should pay attention to the box with 4 layers, safe transportation to prevent rollover during express delivery, the flash drive should also be in the USB port, safety is good.
Q8： Is it harmful to use a flash drive without formatting?
Answer ：The question of whether or not it will damage your data when you are using an unformatted U disk has become more and more focused recently. As flash drives are becoming increasingly popular, more and more people don’t know how to use USB flash drive properly. USB is a non-volatile storage device that does not need any power supply when it is in the standby state (USB interface). When you plug out your USB Flash Drive after using, just like other similar products such as
