Dear experts

,
I'm using AmigaOS 3.9 BB2 with Magellan II as workbench replacement and AFAOS 4.6 on an A4k, CSMK2 060 and PIV.
My ram disk icon is always a standard HDD icon and i'm simply unable to change it to a ram disk like chip icon on something similar. The problem is the same with the FDD and CD icons - when i insert a disk a stanard hdd icon appears instead of a nice FDD icon.
Any recommendation or idea?
