"sounding stupid"? Not at all; that's an excellent question! I suggest looking at the md driver, which provides RAID functionality. To do so, it has to change "virtual" block requests into physical block requests, and in many but not all cases it has to manipulate the data as well. The md driver is in the latest 2.0 and 2.1 kernels; look at the one that matches the kernel you are using. Good luck!
