Modular Hard Disk on Laptop

Greetings, I have a modular hard drive on my Laptop and also have a modular CD ROM driver as well, and i change them out once in awhile. I currently have to turn off my laptop and then turn it back on again to install the other device and use it. Normally in windows you would have to just open a program that would deactivate the device so that you can pull it out then when you put in the other one you can reactivate the new device and it would plug and play it. How can i do this on SUSE Linux 10.0. Does this makes sense. -Cameron
