        Hello Paul , Could you add a little more info like which scsi
        chipset you are using & what the driver version is & what kernel
        version you are running also (One more )& how you have the drive
        chained to the scsi-bus . Someplace there is a pointer on howto
        reset the scsi-bus from the /proc system , BUT the method is
        highly not recommended . Hth , JimL
