Mount and unmount hard drives

Question

How can I mount and unmount hard drives (platform independent, so no using Runtime to execute a hard-coded command) in the Java Programming Language?

Answer 1

Think about it: Java is supposed to work on platforms where no hard drives exist, so how could there be a platform independent way of doing this?
Besides, even if you restricted it to platforms where hard disks are available, how is Java supposed to abstract away the different approaches to RAIDs / partitions / slices etc?

Why do you want/need to do this?
