After years of live upgrades from one OpenSUSE version to the next, the new LEAP 15.2 version will be installed onto a new completely blank system replacing my 8 year old one.
For this purpose, I am trying to get started with the Bootable USB option. The Install Page claims the disk image requires 3.99GB but have not been able to write onto any of my USB drives which are all 4GB. The issue is that the OpenSUSE Studio Image Writer seems to think they are 3.84GB disks! This could be due to formatting overhead but I fully expect to overwrite the entire USB disk and so don’t mind losing whatever is eating up those missing 0.16GB.
Is there a way to write the Bootable USB image directly into the RAW USB disk so that it ignores any file-system overhead?
Is there a way to wipe the USB clean so that it is correctly recognized as having 4GB?
Although not entirely related to the problem, would the Bootable USB image be usable on a device indirectly? Specifically, I have tons of SD and MicroSD cards that are over 4GB and I could use those if it is possible to boot from a USB card-reader, of which I also have plenty.
I still use some USB2 8G drives for installing. They work fine. Most of the install time is in writing to the hard drive (the install destination). The time for reading the install USB is smaller. So the benefits of moving to USB3 seem minor.
