HD activity in 10.04

[Arnaud G]

Hello,

How can I monitor  the HD activity at startup  in Ubuntu 10.04?
When I start up my laptop, sometimes the HD activity goes on for approximately 
2-3 minutes. 

It's not always the case.
It's often before I can login. The gdm is loaded but so much HD activity I 
cannot even move the pointer or enter my credentials.
It sometimes does the same in a non gdm environment. 
Once the HD activity is back to normal, it's OK.

I cannot see a particular pattern in this activity.

I checked my rc2.d/ > rc5.d/ and K'd all the unnecessary services. Same results. 

I disable the disk check at startup, no effect.

How can I log that HD activity to see what is happening. 
Is there any log I should review?.

The disk is ext4 and healthy. The disk model is an ata-SAMSUNG_HM160HI. I am 
running a T60 with 3G of RAM


Did anybody experience that before.

thank you in advance.

A
