     A DDS2 drive
will read DDS1 archives, and write a DDS1 tape in DDS1
 format.  I dunno about DDS3. Every shop I've worked with who used DDS3
 drives used DDS3 tapes exclusively.

 	DDS3 is 125m. Have one right here :) DDS3 drives work fine with DDS2
 tapes, under NT4 and VMS. That's the size combination we're using here at
 work. 
Note that DDS3 drives write DDS2 format when loaded with DDS2 media.
Likewise, DDS2 drives write DDS1 format when loaded with DDS1 media.
