Hardware Bugs: Seagate ST3000DM001 9YN166 3TB Drives Click Noise


  • My brand new Seagate Drives running as Raid1 with two Seagate ST3000DM001-9YN166 on Debian clicks sometimes.


  • Noise is made by parking heads and spin control by the firmware, often seen on Home NAS
  • (Update 2017: The Firmware of this Generation is buggy, Fault rate 70% after 2 Years)


  • go to Manufacter Site and download the firmware update iso
  • burn it to CD
  • reboot the PC on this CD, using Freedos and the Update tool
  • update the firmware and reboot to Linux again
  • edit with sudo vi /etc/rc.conf

/sbin/hdparm -W 0 /dev/sda #Systemdrive disable Cache against Powerloss!
/sbin/hdparm -W 0 /dev/sdb #Raiddrive 1 disable Cache against Powerloss!
/sbin/hdparm -W 0 /dev/sdc #Raiddrive 2 disable Cache against Powerloss!
/sbin/hdparm -S 0 /dev/sdb #Disable Spindown/Poweroff forced!
/sbin/hdparm -S 0 /dev/sdc #Disable Spindown/Poweroff forced!

  • This Parameters should be used on Servers, Performance need running drives not sleeping drives!
  • Every Spindown/Spinup breaks the life of the drives!
