This thread encouraged me to do this on my laptop, but something is
still causing it to not work.
- I set noatime for all my ext3 partitions and this shows when doing
the "mount" command.
the pertinent devices:
/dev/hda6 on / type ext3 (rw,noatime,errors-remount-ro)
/dev/hda4 on /usr type ext3 (rw,noatime)
/dev/hda7 on /home type ext3 (rw,noatime)
- I set the "-m 0" for sysklogd and this shows in the process view
190 /sbin/sysklogd -m 0
- when i run noflushd -d -t 1 /dev/hda
it spins down after 1 minute, but 30 seconds later it spins back up.
How can I find out what is causing this?
thanks,
jc
