- I will confess that we have had some problems with links in the
- past since this machine also has a 1/4" Archive Viper (150 MB QIC)
- attached and we have done a number of links between the various
- drivers and drives. What is the best driver for the Viper?
-
- BTW, this is probably a stupid question, but what is the primary
- difference between the drivers in /dev/mt/tps* and in /dev/rmt/tps* --
- when do you use "mt" and when do you use "rmt"?
-
- Thanks :)
