How to find mounted storage devices in OSX?

How can I find the mounted storage devices and get information about them ? Basically I want a similar behavior like in the finder sidebar. ***Update: Generally I need to show the devices names and types At the moment I am looking into the /Volumes/ directory and just list whats in there, but that leaves me with 2 problems: - I have unwanted items, e.g. MobileBackups - I can not identify the device The second problem is really bugging me. If I could identify the item, I could also sort out the unwanted items, but I do not even know if it is a mounted DMG, USB device, or network device. I already looked at a few examples, but not getting anywhere. The apple sample FSMegaInfo, already gives a bit information, but does I am not sure if I am able to identify the type of device. I am also not sure how I get the required information to scan the device. Also DADiskCopyDescription does not seem to give me the required information. I also use the NSWorkspace notification to get information about new mounted or unmounted devices, but the notification event does not really provide any information. Is there no easy way ? Thanks for the help. Seb
