It could be that DMA mode is not turned on for the IDE channel that runs 
slow. This is enabled on a per-IDE channel basis.

To check, login as an administrator, and right click on "My Computer" and 
select "Manage".
In the "Computer Management" applet, click on "Device Manager".
In the right hand panel, look for "IDE ATA/ATAPI controllers" line and 
click on its '+' symbol (it may be named slightly differently).
You should see entries for your specific IDE controller chipset, and also 
"Primary IDE channel" as well as "Secondary IDE channel". For each of these 
"Primary" and "Secondary" IDE channels, right click and select "Properties".
In the dialog that comes up, click on the "Advanced Settings" table. You 
will see the "Transfer Mode" for each device. If any are set to "PIO only", 
then change it to be "DMA if available" and click "ok".
Once you have changed them all, you will need to reboot.
