Do you choose USB-HDD mode or USB-ZIP mode to make USB disk startup disk?

Select USB-HDD mode when making USB disk startup disk.

USB-HDD: Hard disk emulation mode, which displays drive C after DOS is started, and the U disk made by HP U disk formatting tool adopts this startup mode. This mode is highly compatible. Some computers that only support USB-ZIP mode choose USB-ZIP mode.

U disk startup is a technology to start some backup and restore, PE operating system and other software from U disk. Most computers support USB flash drive startup. It can play a great role in system crash and rapid installation of the system.

Other USB flash drive startup modes:

1, USB hard disk+

Enhanced USB-HDD mode, showing C: disk after DOS startup, with high compatibility. Its disadvantage is that it can't be started on a computer that only supports USB-ZIP.

2、USB-ZIP+

The enhanced USB-ZIP mode supports USB-HDD/USB-ZIP dual-mode startup (depending on the computer, some BIOS may display C: disk after DOS startup, and some BIOS may display A: disk after DOS startup), thus achieving high compatibility.

The disadvantage is that some computers that support USB-HDD will start the USB flash drive in this mode as USB-ZIP, which will reduce the compatibility of large-capacity USB flash drives above 4GB.

3. USB optical drive

CD-ROM simulation mode, DOS can not occupy the drive letter after startup, and its compatibility is general. Its advantage is that XP/2003 can be installed like a CD. Generally, the production tools corresponding to the specific U disk model/batch number are needed for production. For U3 disk network, there are general tools to make it.
