You should draw a little picture of your JBOD cabinet and run the command for each disk to map them out. If you ID all of the good disks, the one that is left must be the bad disk. Once you ID a disk, use your interrupt character, usually cntl-c to kill the dd.
Thx for your help. This probably was the best solution.

NAME

       lvmpvg - LVM physical volume group information file

SYNOPSIS

DESCRIPTION

       is  an  ASCII file that stores the volume-group information for all of the physical volume groups in the system.  The information is stored
       in a hierarchical format.

       First, it starts with a volume group under which multiple physical volume groups can exist.  Under each physical volume group,  a  list	of
       physical  volumes  can be specified.  There must be at least one physical volume group in each volume group that appears in this file.  The
       physical-volume-group name must be unique within the corresponding volume group, although it is permissible to use a common physical volume
       group name across different volume groups.  There can be as many volume groups in this file as there are in the system.

       Instead of using the and commands, the administrator can edit this file to create and extend physical volume groups.  However, care must be
       taken to ensure that all physical volumes to be included in the file have already been defined in their respective volume groups by  previ-
       ous use of or

       The  file  format  has  the  following structure.  and are keywords that introduce the names of the volume group and physical volume group,
       respectively.

	      pv_path
		 ...
	      pv_path
		 ...
	      pv_path
		 ...

       The variables are defined as follows:

	      pv_path	     The block device path name of a physical volume within the volume group.

	      pvg_name	     The name of the physical volume group.  It must be unique within the volume group.

	      vg_name	     The path name of the volume group.

EXAMPLES

       The following example shows an file containing two volume groups: the first containing two physical volume groups, each with  two  physical
       volumes defined in it; the second containing three physical volume groups, each with one physical volume defined in it.
