After doing the “dd” to the raw device, do not do a “sync”, as this is for synchronizing filesystems. Just remove the device.
In case something tried to mount the content of the device (before it was wiped by dd) it might try to write back data to the device and by that action corrupting the freshly written image.

Well 'dd' worked without a problem to clear the PNY 64GB drive I that
was at hand and I put Fedora 33 beta on it:
[root@WS-1 /]# dd
if=/home/bobg/Downloads/Fedora-Workstation-Live-x86_64-33_Beta-1.3.iso
of=/dev/sdc bs=8M status=progress
2028060672 bytes (2.0 GB, 1.9 GiB) copied, 126 s, 16.1 MB/s
241+1 records in
241+1 records out
2028060672 bytes (2.0 GB, 1.9 GiB) copied, 126.227 s, 16.1 MB/s
[root@WS-1 /]# sync
Put the flash drive in the other computer to test, the nedia chck worked
and it started and asked if it should install to disk. That worked
simply enough once I understood the instructions. I will try it on this
box where I want to install to /dev/sdb.
My only concern is getting the standard partition scheme, I may need
media writer for that.
