Can you provide the output of:
$ ps aux | grep devkit-disks
and
$ apt-cache policy devicekit-disks

Certainly, and thanks for looking at it for me:-

Thanks. I thought that perhaps devkit-disks might be polling for a floppy.

That's current.

Just to eliminate devkit-disks, can you please kill the process sr0 and
see if the flashing stops?

$ sudo kill 1765

If not then

$ sudo kill 1760

Note: if you've rebooted since your last post you'll have to check
devkit-disks again to get the correct pid.

OK, tried that. I had rebooted so found the two current process numbers and killed them in order, checking after each one. The one second pulsing of the HDD light still happens. It is once a second because I put a clock next to the computer and checked.


Certainly, if I shut down and restart after disconnecting the SATA DVD writer the pulsing stops. Last night I swapped the Samsung DVD writer for a SATA Optiarc writer but the pulsing continued. I also tried moving the DVD to a different SATA channel but the pulsing continues.


I guess the next thing is to stop the boot at the BIOS screen and see if the pulsing occurs and if so, try booting from another flavour of linux on a live disk. That will take me a few days because the computer is located in a bedroom with no monitor or keyboard/mouse and I'll not be too popular with Xmas coming up.


I also wondered if it might be something to do with the Asus motherboard. I've Googled for quite some time but not come up with anything conclusive. Most people writing about the issue are Windows users.

It's no big deal, and the computer works really well, it's just I'd be interested what is causing the pulsing.


Many thanks for you help.

Ardo.
