 In other words, if your tape has hardware compression, you may be out
 of luck without the exact drive that wrote it.

 So far, we're able to read DDS3 tapes from a Sony drive where
 we used hardware compression in a Sony DDS4 drive, so at least
 Sony is designing some continuity in *their* product line... 
It has been my experience over several years that the only problems
with incompatible hardware compression on DDS drives was with the
original generation of DDS and DDS-DC drives, before DDS2.  The
type of drive that was retro-named DDS1.
