I got a new scsi drive card cable and terminator. I hooked everything up and formated the drive. the drive was freezing up after the format so I rebooted reset the pram and then decided to zero the drive ... the zeroing failed and now the drive does not show up in disk utility on startup the drive spins up clicks 4 times and spins down ... the colors on the drive go from green to orange then the green flashes. everything shows up in system profiler. Also the drive does this when the ribbons are not attached and it just has power... I tried different power adapters also. Any ideas?
