When a USB drive is not recognized by a computer, there are several things that could be wrong. The following are some of the most common problems and their solutions:
The usb device may be defective. Try using another USB port
Issue #2
As you see in the screenshot when people try to eject the USB drive, it says “Eject PenDrive”. It should say “Eject USB drive” or so.
I believe that it happens all of the USBs.
Issue #3
Some of the USBs have a “System Volume Information” folder besides the “KnowItAll Installation” and “Utilities” folders.
(My copy does not have this folder.)
Usb Drive Diagnosis 4
Please investigate why some of the USBs have this extra folder and what it does as well as what does it mean by “X” on the folder icon.
Answer:
To issue 1 : NTFS is a format designed for mechanical hard disks. It will record the read and write operations of the disk in detail. It is a log file system. When used on a USB drive, it will cause a great burden on the flash memory, which will affect the experience and performance of the flash drive to a certain extent. If cilents insist using NTFS format for the 23GB file ,We factory colorusb can add a QC check and make sure that all the tests finished on Win 10 systerm

To rule this out as the cause of your USB woes, just stop Windows from ‘managing’ power to your USB controllers and devices: 1) Open Device Manager (type “Device Manager” in the Windows search field) 2) Expand the Universal Serial Bus controllers branch 3) Double-click the first USB Root Hub device in the list (if you see only one USB Root Hub device, that’s fine) 4) Click the Power Management tab 5) Un-check the Allow the computer to turn off this device to save power checkbox, and click OK . 6) Repeat steps 3-5 for each USB

To issue 3: This folder is a system file automatically generated by the system after the U disk is inserted into the W10 system. On the one hand, our company selected some products for testing on W10 (to prevent W10 system compatibility issues) when shipping, and on the other hand, it may be that the customer has inserted a USB drive into the W10 computer. This type of file has no effect on the USB flash drive, but the W10 system makes a mark on the USB drive. Inserting a USB flash drive into a MAC system will also generate some temporary files. These
files will disappear after the USB is ejected.
Answer: usb device testing process before shipping , make sure all USBs work well on MAC system .
To issue #60; We can do it if they insist using NTFS format for their large file and we factory usbflashdrivesource can add a QC check and make sure that all the tests finished on USB-MAC system.

USB Flash Drive Troubleshooting: How to Repair a USB Drive
In some cases, it is possible to repair a USB drive that is not working properly. This
When these USBs were checked on the computer, all of them could not be written to.
We would like you to investigate this matter and provide a solution.
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 support
ed, 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 obviously 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.
To
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
