    I installed Snow Leopard on my MacBook Air. I tried to install it via remote disc but it kept failing so I used the MacBook Air Superdrive. After the install was complete I have a disk called "Install OS X" if I try to eject the disc it will disappear. As soon as I shut down and restart my computer it reappears again on my desktop. Anyone have suggestions on how to remedy this issue?

    I'm having the same problem.

    I managed to install using remote disk. Every time I turn my Air on I have the same "Install OS X" disk, with the same icon symbol as my Macintosh HD. I can eject it, but after shutting down & turning on again, it's back. It's 2.28 GB, with 2.26 GB free.

    What is that volume? & How do we get rid of it? Any ideas anyone?

    I found a fix for this. Follow these steps:

    1. Click on Macintosh HD

    2. Click on Applications

    3. Click on Utilities

    4. Click on Disk Utility

    5. Click on your Hard Drive on the right column at the top. It should say XX GB

    6. Click on Partition

    7. Click on the Snow Leopard Partition and click "-"

    8. After you delete the partition, under Volume Scheme drag your Macintosh HD to fill the entire box. This will reclaim the hard drive space created by the partition

    9. Click Apply

    This should work if it does not let me know and I will see what the problem is.
