I have a Connor 4326RP 4mm DAT tape drive (4 Gb native capacity).  I'm 
having trouble making backups of a DECstation 5000/200 running Ultrix 
4.4.  When I attempt to do a dump, it will not use the tape density I 
specify.  The tape drive writes at 6,000,000 bpi, but dump's limit seems 
to be 61000.  If a number higher than this is specified, it uses 61000 as 
the density.  The only way to make a backup is to specify an absurdly 
long tape length (10000 feet).  When I do this, the dump seems to go ok, 
but I get errors upon restore (for example, "error while skipping inode 
225").  Any ideas?  Is anyone using this tape drive successfully with a 
DEC 5000?  Thanks.
