I checked the source code on our Harris HCX-9, see a part of
the comments below:

   /* The BIG parameter is machine dependent.  It should be a long integer  */
   /* constant that can be used by the number parser to check the validity  */
   /* of numeric parameters.  On 16-bit machines, it should probably be     */
   /* the maximum unsigned integer, 0177777L.  On 32-bit machines where     */
   /* longs are the same size as ints, the maximum signed integer is more   */
   /* appropriate.  This value is 017777777777L.                            */
   #define BIG	017777777777L

The value 512k is checked against BIG to see if you're using a reasonable
output buffer size. Well, dd concludes you're not :-)
I guess you're on a 16-bit machine, sorry...
