I think this is because your drive is not set to fixed block mode for  
restore which it was during dump.  What I do, and this has ALWAYS worked,  
is a 

localhost:4# restore i
/dev/rxt0: I/O error

Then I do a

localhost:5# restore if /dev/nrst0

and the restore works just fine.  The default device for tape is /dev/rxt0  
which, if I remember correctly, is a exabyte device which uses a fixed  
block length....

I hope this helps...
