HDD-fat32 and HDD-fat 16 are hard disk simulation modes, both of which are file allocation table systems, which can be simply understood as the difference between 32 bits and 16 bits.
Zip-fat32 and zip-fat 16 are a method to write image files in compressed form. A disk is displayed after DOS is started, and this mode is adopted by USB-ZIP startup USB flash drive made by FlashBoot. This mode is the only optional mode on some older computers, but it is not compatible with most new computers, especially large-capacity USB flash drives. ?
HDD-fat32 and HDD-fat 16 are hard disk simulation modes, and C: disk is displayed after DOS is started, which is the startup mode of U disk made by HPU disk formatting tool. This mode is very compatible, but it can't be started for some computers that only support USB-ZIP mode. HDD-FAT32 mode is suitable for new computers.
Extended data:
FAT (file allocation table) means "file allocation table". It is a table used to record the location of files, which is very important for the use of hard disks. If the file allocation table is lost, the data on the hard disk will be unusable because it cannot be located.
FAT 16 is called fat 16 because it uses16 bits to represent the situation of each sector configuration file. ?
FAT 16 is limited, so the cluster size used by FAT 16 must be expanded after each partition has a certain capacity to adapt to the larger disk space. The so-called cluster is the allocation unit of disk space, just like the bookshelf in the library. Every file to be saved to disk must be configured with a sufficient number of clusters before it can be saved to disk.
FAT32 file system?
In order to solve the problems existing in FAT 16, FAT32 system was developed. FAT32 uses 32-bit space to represent the situation of each sector configuration file. FAT32 can use a single partition up to 2TB(2048GB), and the size of clusters that can be used by partitions of various sizes is also appropriate. These two advantages make the use of hard disk more efficient.
