Since both the Adaptec 274X and the Archive Viper are known to work rather well under FreeBSD (i've been using a Viper 150 for almost two years on my BusLogic 742A [also EISA] controller before i upgraded the drive to a Tandberg 2.5 Gig one), this smells like some SCSI bus problem (cabling, termination, ambigous term power, etc.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
