Does this occur only in 3.3-RELEASE ? Is it a problem of the wd driver only? I tested this on 4-STABLE with ad driver for atapi disks, and dd(1) works for me. With floppies, it works too. I even tried copying a floppy to a raw disk device ( Can you please provide with more information on this? I'm most interested to know a) if this bug appears only in 3.3-RELEASE or is present in newer 3.x releases too b) if this is a bug of the wd driver, or you seem to be having the same problems with ad driver too.
