How to list drives as install destination?

I need to list all Drives of the system so the user can select one drive as destination directory. The problem, only FAT and FAT32 partitions should be listed/selectable. Is there any possibility to do this (as a replacement to the select destination directory)?

if dll file would be required it's no problem, i know how to write them.

There is a page in the archive which describes how to get all avaialble drives and how to detect their type. Once you got the list then you could create a custom page with a dropdown combobox from which the user can chose which drive to install to.
