bcwipe won't wipe a block device...

I don't know if this is a problem specific to CURRENT or not, but bcwipe
seems to do the right thing when wiping files.  however, when using the -b
option to wipe an entire block device, there is an "Invalid Argument"
error, and I don't understand exactly why...

fbsd52# bcwipe -bvmd /dev/da0
Wipe /dev/da0 (y/[n]/a)?a
Wiping device      /dev/da0
Writing to /dev/da0: Invalid argument
fbsd52# bcwipe -bvm3 /dev/fd0
Wipe /dev/fd0 (y/[n]/a)?a
Wiping device      /dev/fd0
Writing to /dev/fd0: Invalid argument
fbsd52#

these are examples of commands verbatim from the bcwipe man page...  The
devices exist in /dev/, and there is a floppy in the drive...  This is the
dmesg for the USB hard disk that I'm ultimately trying to wipe...
