What does USB-FDD, USB-ZIP and USB-HDD mean? Resolved

 If you want to repartition or format a USB stick, for example to make it bootable, you have to choose one of the following options in the software used for this, such as Memtool or Rufus: USB-FDD, USB-HDD, USB-ZIP.

But what do the individual SB options mean for the bootability of the stick?


What do I have to consider? We would like to give you a detailed answer to this question here:

What USB options are available for the bootable stick?

If you select this setting, the USB stick is recognized by the computer or the BIOS like a normal floppy disk drive. The partition size is a floppy drive of 1.44 MB.

Especially on older computers this setting makes sense, so that the USB stick can boot properly.

With this option, the computer recognizes the USB stick as a hard disk or a USB stick. This setting is valid for most computers

We therefore recommend to select the setting "USB-FDD" for the bootable stick.

In the past there were ZIP disk drives with memory sizes of 100 MB. If you select this setting, a ZIP disk drive is recognized when you connect the USB Sick to the PC.

Which setting is right for me?

Here it depends on which setting the bios of the computer supports. Normally USB-HDD is used. This is the highest probability with modern computers that the USB stick can be booted.

You now know the meaning of the different USB options available to you when creating a bootable USB stick.
