Ever since I encrypted my MacBook Pro I am seeing this error right after I type in my password at the initial screen.

Any ideas what this means, how serious it is or maybe even how to fix it?

Apologies for the smudginess and reflection in the pic - it's displayed for a fraction of a second and it's the best one I've managed to take.

What is really is might be a bit of a guessing game, but the next step is clear.

Boot to your Recovery HD and see what disk utility makes of the volume itself.

If you lack a Recovery HD - then it's time to make a back up of any files you can reach (attach the drive to a sled / boot in target mode / install the OS to an external drive and copy things off using another OS.)

At that point, you can re-run the installer which may fix the issue for you and will certainly get you back to having an Recovery HD or expose a hardware problem if you can't even re-instal the OS on top of the data that is there.

  • Unfortunately, for whatever reason I have no Recovery HD to choose. There's only OSX drive and that's it. I'm on the latest stable Lion.

  • I did run the Disk Utility from Lion though. There were few permissions wrong which it fixed, the volume verification went alright, but that didn't fix the issue.

  • And - without a recovery HD - it begs the question: How exactly are you encrypting your disk? I had assumed FileVault - but I might be answering what to do when FileVault fails - not what you've managed to change with some other encryption tool.

  • Yes, it is File Vault encryption. I think I've had a Recovery HD before I encrypted the drive, but I'm not entirely sure. Anyway, the OS seems stable, but any Error is not good hence my question. I do have a Time Machine backup and another Carbon Copy Cloner backup so I am "insured" for a drive fail. I think I'll look at installing the OS from scratch and restoring the files from backup. Thanks for your help.

  • Btw. I find it interesting that the error messages have typos - coundn't - that's not Apple-like.

When the system disk is filevaulted, you will not see Recovery HD in the boot menu (pressing alt during boot). Try holding Cmd-R during the boot (press the combination immediately after you hear the Apple chord if you didn't disable it).

It's just some image files that are missing, so I'd say not too serious.
