Configure Write-Back on 80-pin SCA-2 Seagate Cheetah drives with Adaptec RAID Controller

I'm looking to enable Write-Back for my Seagate Cheetah drives and the manual says that the jumper setting are configured through 'drive to host I/O signals on the LC model', which I have.  So, how do I configure them?  Is it using that Apatec Contoller or using tools downloaded from Seagate?

If it adds to the info, the Adaptec RAID controller is ASR-2120S.

With a RAID controller, the cache type is usually handled on the controller. That's been my experience with the Adaptec brands.

If it's available it will be on the devices menu. Bit of a gamble enabling write-back on the disks though.

OK, so I've got it all up and running, just I have no idea how to set or tell if the drives are set to Write-Through.  In Adaptec System Manager, I can click on the Logical Drives and set Write-Back or Write-Through, but when I click on the Physical Drives, there is no option.  It says in the Help that I should be able to right-click on the physical drives and set them to write-through.

Also, once the drives are added to an array, there is no option for configuring anything for the physical drives...ugh.  

The options before becoming an array are:
- Hints and tips
- Create Simple Drive
- Create Dedicated Hot Spare Drive for ...
- Create hot-spare drive
- Initialize
- Verify
- Verify w/ fix
- Clear
- Blink physical drive
- Properties

Under properties, there is no mention of write-back/write-through.
