Firmware Question?

This might be a stupid question but, I am unsure where the actual firmware is stored. If I used binflash and updated my firmware for my external dvd burner, but then recently had to reformat my computer do I need to do it again?

So long as the flash is successful and the flashing program tells you the flash was completed, you don’t have to reflash. Now, if you stored the .zip/.exe file that was the f/w update and want that file just to have for some reason, you’d obviously have to redownload it and save it to a folder on your computer.
