- 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!
