USB-FDD USB-HDD usb zip difference

1. ZIP mode refers to simulating a usb flash drive into a zip drive mode. After the USB flash drive is started, the drive letter is mostly :,
2. HDD mode refers to simulating a USB flash drive into a hard drive mode. Note: If HDD mode is selected, the drive letter after starting the USB flash drive is C :, when operating on the Start partition, there are many problems.
For example, when installing the system, the installer will write the boot file to the USB flash disk instead of the boot partition on your hard disk! The system fails to be installed. Therefore, try to select the ZIP mode first.
3. FDD mode refers to the U disk simulation into A soft drive mode, after the boot U disk drive letter is A:, this mode of U disk in some support USB-FDD boot machine boot will not find U disk, therefore, use it as appropriate.
The basic dossystem only loads the three core DOS Files, IO. SYS, MSDOS. SYS, and COMMAND. COM, without loading any other drivers and programs.
Use the restart key to select the desired start mode. Press enter to confirm.
After the startup is SUCCESSFUL, the words dos loading successful are displayed.
If the USB flash drive is in ZIP or FDD mode, A prompt of A: \> appears.
If it is an HDD-mode USB flash drive, a C: \> prompt will appear.
So far, the DOS system has been started.
Note:
1. Back up the useful data on the USB flash drive before making the boot disk. It is best to format the USB flash drive completely.
2. For a hard disk or multiple hard disks with NTFS partition, the drive letter arrangement on the hard disk under DOS may be different from the order in Windows. Please find and confirm it by yourself to avoid misoperation.
If a problem occurs during use of the USB flash drive, try the following method:
Change a to another working mode (ZIP, HDD, FDD );
B. Select other options in the DOS Startup menu;
The main reasons for the problem are:
Motherboard a does not support USB Flash boot (or is not fully supported );
B. Some DOS software (especially for disk operations) may not support USB flash disks very well;
The c-USB flash drive is a new hardware that emerged after DOS and has a complicated variety. At present, the vast majority of USB devices do not have a DOS driver. Currently, they are basically compatible drivers, therefore, some problems are inevitable;
