>Description:
I think the following extract from pciconf -lv represents the chipset of my SATA controller:

atapci1 at pci0:0:9:0:     class=0x010185 card=0x360a103c chip=0x0ad010de rev=0xa2 hdr=0x00                                                                        
    vendor     = 'Nvidia Corp'                                                  
    device     = 'SATA Controller IDE mode (MCP78)'                             
    class      = mass storage                                                   
    subclass   = ATA             

And this appears in dmesg:
ad6: 238475MB <Seagate ST9250320AS HP07> at ata3-master UDMA33        

I noticed that my laptop becomes really slow when copying files or using the hard-drive a lot.

Laptop is a Compaq Presario cq60-213ef
>How-To-Repeat:
Copy files and try to do something else (like browsing with firefox).
