diskejectd

If your Mac OS X box has volumes that OS X does not recognise, e.g. Linux volumes partitioned with ext4, you will be bugged with a popup stating "The disk you inserted was not readable by this computer" on every boot.

Unfortunately, OS X doesn't read volume names of some (all?) ext4 volumes, nor does it recognise their UUIDs, which makes it impossible to use /etc/fstab to block the volumes.

This Launch Daemon resolves the problem by blocking disks by their disk name. Disk names have to be specified in <ProgramArguments> of com.diskejectd.plist. It helps you to block/get rid of "the disk you inserted was not readable by this computer" error message in Mac OS X.

Based on original code published at: superuser.com

Installation

1. Get the BSD Disk Name of the disk you want to block with diskutil list, e.g. disk2s2.
2. Put disk names you want to block in <ProgramArguments> of com.diskejectd.plist. You can put as many disks in there as you like. Here's an example for blocking two disks:

<key>ProgramArguments</key>
<array>
    <string>/usr/local/sbin/diskejectd</string>
    <string>disk2s1</string>
    <string>disk2s2</string>
</array>

Finally, compile and install:

1. make
2. sudo make install
3. sudo make start

Removal

1. sudo make stop
2. sudo make uninstall
