Disable PMBPORTABLE disk
Every time you plug a Sony camcorder into a Mac, two disks mount. One of them, called PMBPORTABLE, is unnecessary. This is how to get rid of it without making any changes to the camera.
The PMBPORTABLE disk contains some kind of Sony software. I’ve never used it, and I don’t want to, so it bugs me that I have to eject it every time I want to disconnect my camera. The solution is to tell the computer never to mount this disk. Enter this into the terminal:
echo "LABEL=PMBPORTABLE none msdos ro,noauto 0 0" | sudo tee -a /etc/fstab
Enter your password when it asks. You’re done.
We’ve told the computer to ignore all drives named PMBPORTABLE. If you want to undo this, enter this command and restart your computer.
sed '/PMBPORTABLE/d' /etc/fstab | sudo tee /etc/fstab
