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.
Answer：Comprehensive answer to question 1. Storage industry standard: The actual
capacity of the USB flash drive is not less than 90% of the nominal capacity is a qualified
product.
The actual capacity range of some common capacity USB flash 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.
Answer：
Generally speaking, there are three formats of USB flash drives, which are produced because of their different needs.
FAT, FAT32, exFAT.
Early U disk capacity was small. It is in FAT16 format. Referred to as FAT format. Now USB flash 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, so
the 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 flash 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 flash 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.
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)
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.
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
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 USB 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.
