I have an external 2 TB LaCie drive connected via FireWire 800 to my MacBook Pro (8,2 – early 2011 model), which runs OS X 10.8.5. It has one big partition which is a Time Machine target, and the backup is encrypted. My Macintosh HD itself is also encrypted.
Before, I could just plug in the drive and it would automatically mount all the volumes on it, but ever since I've enabled encryption and started a new Time Machine backup, the disk is not mounted automatically anymore – I have to go into Disk Utility and manually unlock it:
Sometimes I even have to enter my master password for that drive.
Of course, that's not really practical: it's a backup drive and therefore should be mounted automatically every time it's plugged in.
I have not changed my
/etc/fstab to prevent it from mounting, nor have I changed any configuration regarding mounting or Time Machine. Here's the
diskutil list output for the sake of completeness:
/dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *121.3 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_CoreStorage 120.5 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Macintosh HD *120.1 GB disk1 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *2.0 TB disk2 1: EFI 209.7 MB disk2s1 2: Apple_CoreStorage 2.0 TB disk2s2 3: Apple_Boot Boot OS X 134.2 MB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Data *2.0 TB disk3
How do I get OS X to mount my volume automatically again?
NB: I also noticed that as soon as I eject the drive, it doesn't spin down anymore. It used to do that before though – now I have to shut it down with the hardware switch.
