Getting Drive icons

In connection to Gus' tutorial about the tripple drive buttons I was wondering how I could add the different icons for different drive types?

right now i have the dynamic drive toolbar which gives me e.g. a floppy icon for A:. now if i set it up all manually i'd like to add that icon manually - and others for other types of drives. Now they do not exist in the DOpus icon collection but i guess they are certainly stored in a Windows system file. but in which one?

Pascal

shell32.dll

thanks jon.
