I often use dd command for filling my USB with zeroes and then later formatting it using the style that I want. However, my USB stick is 16 GB and it takes around 40 mins for dd to fill it with zeroes. I just want to erase the partition details so that the USB appears to be non-formatted instead of actually filling it with zeroes. Is there some option that I can use with dd so to stop filling the USB after a certain amount of disk if filled with zeroes? I suppose this would not render my USB unusable.
any help will be greatly appreciated.
