I don't usually use the 'conv=fsync', but it's good practice. Instead, I got into the habit of doing an 'eject' on the device before I pull it out of the USB socket.

I've never used anything other than 'dd' for writing .iso images to flash drives. I never understood why anybody ever thought they needed to write/use an app for that task. -- Grant
