thanks for taking an interest - I re-installed lenny from scratch and these error messages don't appear any more. Plus the clicking has gone. The brute force solution!

It still would be good to check the drive with smartmontools, unless you don't care about your data.

OK will do.

My only problem now is with the video signal powering down after 10 mins. I can't find the configuration setting anywhere and searching the internet has so far only turned up people in the same situation - it's not the BIOS, it's not X (it happens on the command line too), and I can't see any settings in /etc that might regulate it.

Check /etc/X11/xorg.conf file (look for "OffTime" in xorg.conf(5).

Check /etc/console-tools/config file:
 BLANK_TIME=0
 BLANK_DPMS=off
 POWERDOWN_TIME=0
I suggest setting them that way and see if it makes a difference, then adjusting later if necessary.

In X, what is the output of:
$ xset q | grep -i dpms

according to the man page, the default for OffTime is 40 mins, but my signal
power-down happens after 10 mins.

The xset output is:
DPMS (Energy Star):
  Standby: 1200    Suspend: 1800    Off: 2400
  DPMS is Enabled
  Monitor is On

interesting. In /etc/console-tools/config I have:

BLANK_TIME=30
POWER_DOWN=30

Again, interesting but not 10 mins. In the comments, there's a line that says:

# screen blanking timeout.  monitor remains on, but the screen is cleared to
# range: 0-60 min (0==never)  kernels I've looked at default to 10 minutes.
# (see linux/drivers/char/console.c)

So I am getting the kernel default. Presumably there's a way to get lenny to use these settings in /etc/console-tools/config - I'll have a search.


Thanks
Adam
