I couldn't change the backplane as I don't have a spare one. But there is one thing though that crossed my mind just seconds after I've hit the 'send' button! I periodically check (every minute) the drive temperature using 'smartctl -a' and I only query one drive - '/dev/sda'! So I re-checked my log files and indeed - the SATA error ALWAYS happens within one second of the 'smartctl' command (but not every time). So now I changed the scripts to query a different drive ('/dev/sdb'). In a couple of hours I should know if that was it... Thanks for the help, Danilo PS: Oh, one more thing - the 'sda' drive is a WDC, while all the others are Seagate. > Then replace the faulty components. > > Best regards, > > Wolfgang Denk > > -- Danilo Godec, sistemska podpora Predlog!
