I'm experiencing something strange the two USB flash disks:
(1) an 8GB USB flash disk
(2) an 16GB USB flash disk
... both are from the same manufacturer.
I downloaded FreeBSD-13.0-RELEASE-amd64-dvd1.iso using a Mac, and executed the same command below to write to the two USB flask disks:
# dd if=FreeBSD-13.0-RELEASE-amd64-dvd1.iso of=/dev/da0 bs=1m conv=sync
The 8GB disk refuses to boot up. I've tried doing it a few times and the result is the same.
The 16GB disk always boot up fine.
However, the 8GB disk can be formatted as FAT and works really fine for copying data files between the Mac and the FreeBSD machine.
It's really puzzing what's wrong with the 8GB disk as the process to burn the FreeBSD-13.0-RELEASE-amd64-dvd1.iso is exactly the same for both 8 GB and 16 GB disks.
Why does the 8 GB disk refuses to work as a boot up disk?
If the 8 GB disk is corrupted, why does it function so well as a data transfer disk?
This is a great mystery to me. Anyone has some insights?
