Which Win 7 32-bit USB disk drivers to use for custom recovery CD?

Hi, all...

I'm running Windows 7 64-bit, and would like to create a custom recovery CD for my laptop. Since 32-bit drivers are required (groan), which 32-bit drivers for external USB disks should I add when creating the customer recovery CD? Is there a generic Windows 7 one? I need full path, please. Thx
