If you google dd for windows there are some equivalents like http://uranus.chrysocome.net/linux/rawwrite/, but it depends on what you are trying to achieve.  If private region has become corrupt and SFW cannot delete disks, then you can use dd to overwrite private region, but I think the use case for this is pretty rare, but if you are trying to erase the data for security then better to use vxassist shred - see extract from SFW admin guide:

 

vxassist shred
vxassist [-f] [-g<DynamicDiskGroupName>] shred [shredtype=<0|1|2>]
<VolumeName | DriveLetter |VmName|DrivePath>
Overwrites the entire volume with zeroes and then deletes the volume.
SFW provides the following methods for overwriting the volume:
■ 1 Pass algorithm
   Overwrites the volume with a pattern of zeroes.
  Specified by shredtype=0.
 
■ 3 Pass algorithm
   The volume is overwritten a total of 3 times. The volume is first overwritten
  with a pre-selected digital pattern, then overwritten with the binary
 complement of the pattern. In the last pass, the volume is overwritten with a
randomly selected digital pattern. This 3 pass approach is based on the
specifications in the US Department of Defense standard 5220.22-M (3).
Specified by shredtype=1.
 
■7 Pass algorithm
The volume is overwritten a total of 7 times. Each pass consists of overwriting
the volume with a randomly selected digital pattern or with the binary
complement of the previous pattern. This 7 pass approach is based on the
specifications in the US Department of Defense standard 5200.28-STD (7).
Specified by shredtype=2.
 
SFW defaults to the 1 Pass algorihm when shredtype is not specified.
 
Examples
vxassist shred J:
The above command shreds volume J.
