Thanks for the information, everybody pretty much agreed that as long
as I use the 120M tapes the DDS3 should automatically recognize that as
a DDS2 tape and write in the proper format. The relationship between
tape length and DDS format is as follows:

     TYPE MAXIMUM TAPE NATIVE ADVERTISED CAPACITY
                   LENGTH (meters) CAPACITY (Gb) W/COMPRESSION (Gb)
     ------------------------------------------------------------------
     Single drives:

     DDS-1 60 1.3 2.6

     DDS-DC 90 2 5

     DDS-2 120 4 8

     DDS-3 125 12 24

     DDS-4 150 20 40

     ------------------------------------------------------------------

Finally, someone pointed me towards the http://www.hp.com/ and suggested
searching for DDS since they make the DDS3 and DDS4 tape drives that Sun
re-sells.
