Forcing partition table reading & disabling auto-mounting

Two semi-related questions here:

1) Is it possible to force OSX to check for the presence of a recorded
CD?  I'm using the open-source cdrtools utilities for doing CD burning
on a custom application and after a CD is burned, the only way I can
get the OS to recognize the presence of a disk in the drive is by
ejecting the tray and re-loading it.

2) How can you temporarily prevent OSX from mounting all volumes on a
newly-inserted disk?  I need this behavior for verifying the contents
of the disk.

I imagine that both of these things are possible, since I've seen this
behavior in other programs before.  I suspect both may involve the Disk
Arbitration framework, but it's a private framework with no
documentation.

Any ideas?

Thanks.
