I've installed a Seagate 17g 10K SCSI drive in my AGP Graphics G4 466mhz on my adaptec 39160 card...system profiler sees the drive OK but everything that I've tried fails to initialize it. started up in OS9 to run "drive setup" but get an "initialization failed" message there. "disk utility" in OS X gives me an "unknown error" message when I try to "ERASE" the drive. (?) Thanks!!
