Why must a USB flash drive booted in UEFI mode use the FAT32 file system? (Recommended learning:web front-end video tutorial)
Because NTFS is a file system exclusive to Windows systems, and UEFI currently does not support NTFS.
So, if you select "UEFI boot only" in the motherboard settings, the NTFS formatted boot USB drive will not be visible in the F12 boot options;
If it is set to "UEFI boot and compatible with old mode", then although the boot USB disk can be seen in the F12 boot option, it will be a normal BIOS boot after choosing to boot.
Note: In the F12 boot options, the UEFI boot options will have a prefix "UEFI: ".
FAT32 is a type of partition format. This format uses a 32-bit file allocation table, which greatly enhances its disk management capabilities and breaks through the FAT16 limit of only 4 GB per partition.
Due to the current decline in hard disk production costs, its capacity is getting larger and larger. After using the FAT32 partition format, we can define a large hard disk into one partition instead of dividing it into several partitions, which is very convenient. Management of disks.
However, because a single file larger than 4GB cannot be stored in the FAT32 partition, and the performance is poor, disk fragmentation is prone to occur.
Currently, hard disks have been replaced by the NTFS partition format with better performance, and U disks have been replaced by the exFAT partition format that supports single files larger than 4GB.
NTFS (New Technology File System) is the file system of Windows NT environment.
The new technology file system is a restricted-level dedicated file system of the Windows NT family (such as Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10) (where the operating system is located) The file system of the drive letter must be formatted as the NTFS file system, in a 4096 cluster environment).
NTFS replaces the old FAT file system.
NTFS has made several improvements to FAT and HPFS, such as supporting metadata and using advanced data structures to improve performance, reliability and disk space utilization, and providing several additional extensions.
The detailed definition of the file system is a trade secret, and Microsoft has registered it as an intellectual property product.
In Windows Server 2012, Microsoft once again introduced the new ReFS file system to enhance some functions of NTFS. It provides complete data verification, active error correction and data salvage features and maximizes reliability. sex.
