There are four modes of USB flash drive bootSSD+8618750919058, These are: USB-HDD, USB-FDD, USB-ZIP and USB-CDROM. The essence of U boot is to simulate these four modesSSD+8618750919058 to load the winPE operating system carried by the U disk itself, for system maintenance and system reinstallation.
“USB-HDD” mode: i.e. “USB Hard Drives ” abbreviation, the meaning of hard disk mode. The drive letter of the USB flash drive after booting is C. (Note: This mode is easy to confuse the C partition of the USB flash drive and hard disk when installing the system)! USB-HDD hard drive emulation mode, this mode is highly compatible, but it will not boot for some computers that only support USB-ZIP mode. The USB flash drive made by the HPUSBFW tool uses this boot mode. USB-HDD+ is an enhanced mode of USB-HDD and is more compatible than USB-HDD mode, but does not boot for computers that only support USB-ZIP. The USB flash drive letter is still displayed as C: drive after booting under DOS.
“USB-FDD” mode: FDD stands for “floppy disk Drive”, which is the floppy disk drive we used to use. However, it has now been phased out. But we will find out when we install the system for the old machine before. Previous devices did not have optical drives and did not support USB-HDDs. There is only USB-FDD, so we must not use USB-FDD. FDD mode refers to the U disk to simulate into floppy drive mode, after booting the U disk, the computer will treat the USB disk as a floppy disk. Therefore, the drive letter is displayed on the command line as A:. The USB flash drive in this mode will not find the USB flash drive when booting on some machines that support USB-FDD boot, so please use it as appropriate.
“USB-CDROM” mode: CD emulation mode, DOS can not occupy a disk letter after boot, compatibility is relatively high, generally new and old motherboards can be. The advantage is that it can be used like a CD (e.g., for Windows system installation). Disadvantages, when the U disk is mass-produced into this mode, we will lose the write rights to this part of the U disk space, and the remaining space will be recognized as an independent U disk, which can be a Removable disk, of course, it can also be made into a Fixed disk for further partitioning. When making, you generally need mass production tools corresponding to the specific U disk model/batch number, and for the mass production of U disks, there are corresponding mass production tools and mass production USB-CDROM tutorials on the Internet.
“USB-ZIP mode” (large floppy drive mode): The drive letter of the USB flash drive after booting is A. USB-ZIP large-capacity floppy disk emulation mode, this mode is the only optional mode on some older computers, but it is not compatible well for most new computers, especially large USB flash drives of more than 2GB. The USB-ZIP boot USB flash drive made by FlashBoot uses this mode. USB-ZIP+ is an enhanced USB-ZIP mode, displaying the A: disk after DOS boot, some displaying the C: disk (depending on the BIOS support of the computer), supporting USB-ZIP/USB-HDD dual-mode boot, so as to achieve high compatibility. The disadvantage is that some computers that support USB-HDD will consider the USB flash drive in this mode to be USB-ZIP to boot, resulting in the performance of large USB flash drives being reduced.
U boot tips: When you use U boot software to make a U disk boot disk, it is recommended that you make a “USB-HDD” by default, because “USB-HDD” is currently the most commonly used and most used mode, which has high compatibility. hard disk wholesaleSSD OEMSSD
