I've been using an Archive Viper 150 for a long time (lately been replaced by a Tandberg 3660). I never had problems with it, neither with an Adaptec AHA-1540A, nor with the BusLogic Bt-742A i'm using now. The tape usually kept streaming, resulting in 250 - 300 MB/h backup speed. I remember that the Viper 150 has an additional jumper block (the middle row) which determined some kind of a block size. The setting of these jumpers actually had an effect on the possible speed of operation, but i cannot remember the setting i've been using. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
