If you're too cheap to get a proper backplane or 1" drives, your time 
isn't worth much, and don't mind possibly ruining the backplane, you 
could just "remove" every other connector.  I did that to a Sparc 5 SCA 
backplane to fit a 1.6" drive (removed the top connector using pliers 
and a very sharp pocket knife that had to then be resharpened 
afterwards).  It "works" but I wouldn't do it to anything I valued.

However, some 1.6" drives do have the SCA connector sticking out the 
back so that they fit into backplanes for 1" drives.  4GB Seagate 
Baracudas (ST15150x) come to mind... and are the only drive I've seen 
like that.
