Something keeps accessing the hard drive every 10 seconds approx.
I don't believe it is hardware related as the hardware is new and it doesn't
occur when booted to winxp. (I am going to wipe xp when the warranty is
over).

Is there a way to tell what is causing the access to the drive?

Some kind on monitor?

I tried google but I couldn't figure out a good search string

.

Anyway thanks

The journalling of the filesystem (and a couple of other things) are
accessing the drive, review the /var/log/messages (as root) for the
details. Hints: smartd commit ext3

Examples;
Dec 28 11:33:52 Aspire5000 kernel: kjournald starting. Commit interval 5
seconds

Dec 28 11:34:08 Aspire5000 smartd[1738]: Device: /dev/hda, is SMART capable.
Adding to "monitor" list.

I have smartd turned off, I thought it may have been the one so I turned it
off.

Yes found that:
/var/log/messages

ec 28 18:28:19 scrat kernel: kjournald starting. Commit
interval 5 seconds

If I follow you here

It is the journalling that is hitting the drive,
correct?
If so I think I will have to demote it from ext3 to ext2 to get it to stop
is that correct?

I do not know if that is what causes the commit to disk but if you are going to
shut off the journaling you should change the fstab type to ext2 and get back
the journaling space. However this will require the disk to recover from
screw-ups at boot time which takes about 15-20 minutes for 40G drives.

I tried to convert back to ext2 by:
changing /etc/fstab entry for the filesystem.
tune2fs -O ^has_journal /dev/sda7
e2fsck /dev/sda7

upon reboot got a kernel panic - something about journal not found

so I tune2fs -j /dev/sda7
and rebooted. Now no kernel panic and the filesystem is mounted as ext2 but
I still have the hard drive access every 5 to 10 seconds.
Can I turn off kjournald?
If so how?
