Yes -- on Darwin/Mac OS X you can't use the "umount" command to unmount disks. The problem is that the BSD umount command doesn't tell the other layers of the OS about the unmount.

The correct command is:

sudo diskutil unmountDisk /Volumes/Neverhood

This will dismount the specified volume, as well as any other volumes on the same physical disk.

$ sudo umount /Volumes/(...)
Here's something strange that the CD icon didn't disappear like the description? And once it finished "dd ...", I still couldn't reject the CD! It says that the device is busy, and even I couldn't mount the device?

I've tried to type "df -k /Volumes/*", but showed that the all mounted device became the same as the label of my only hard disk, like
Filesystem              1K-blocks     Used   Avail Capacity  Mounted on
/dev/disk0s3             58474008 55904412 2313596    96%    /
/dev/disk0s3             58474008 55904412 2313596    96%    /
/dev/disk0s3             58474008 55904412 2313596    96%    /
Could someone help me? Thanks.
