I managed to UDF format my USB drive following the instructions in Using UDF on a USB flash drive. Later, I came by this post and I began to doubt...

Could anyone explain which would be the "best" way of UDF formatting a USB drive taking into account both the question and the link provided? (I'm assuming that the link is trustworthy, but could be mistaken.)

Additionally: the linked question talks about zeroing the first sectors of the USB drive, I usually just go:

cp /dev/zero > /dev/sdX

and Ctrl+C my way out of it... does anyone know exactly how many bytes should be zeroed? (a snippet would be nice too :) )

You should zero at least 2048 bytes because UDF needs the first 2K area.
