OSX Lion and encrypting WD external drive

I have been inquiring since last July about the ability to encrypt an external WD 3TB My Book Essential HD. This was a new feature in Lion using Disk Utility (different than File Vault 2 configured via System Preferences for the interal HD). I have been told by Support that this is coming, but it has been months now. Where does this stand?

Before you tell me to use the hardware based encryption in the drive itself, be aware that the WD drive locking feature is NOT compatible with Time Machine and I have also reported this previously.

My HD info:

My Book Essential 3 TB

Serial number: 

Firmware Rev: 1.016

WD Smarwware 1.3.3.8

Thanks,

Marc

This is a feature on Lion if is not available then not much can be done

The Smartware IS compatible with TM … the only thing that you need to make sure is that drive is unlocked at the time of the scheduled backup.

You can also use any other software to encrypt the drive

Hi,

You may alreayd be aware, but the latest OS X Lion update (10.7.3) recitfied this known issue.  FileVault2 can now successfully format and encrypt these drives.

Actually, I was not, nor did I see anything obvious in the description of the update, which I had installed previously.

Thanks for the heads up on this. In light of the comments over the prior months from WDC’s own support folks that this was a firmware issue, I was not looking to Apple for OS updates to resolve this.

It appears to be working now.

Thanks again!

Wizer, just following your answer - I may have the same issue.

When you say “The Smartware IS compatible with TM … the only thing that you need to make sure is that drive is unlocked at the time of the scheduled backup.” I’m confused (and I’m new so please excuss me): My understanding is that TM is automatic (every hour) - does that mean I need to Unlock the drive each time I mount it (attach it) to my Mac?

Thank you, Eric

Thank you, Eric

Yup. you’ll also need to unlock if the computer or drive goes on hibernation sometimes 

Thanks for the answer - I guess in that case it doesn’t really make sense to use the hardware encryption, does it?

Also, it doesn’t seem to take much time to envoke the ecryption - is it encrypting the data itself, or just the HD driver, i.e. access to the unencrypted data?

Thanks, Eric

That depends on what you want the drive for… the encryption comes handy when multiple people have access to the drive> The data will not be accessible unless you unlock the drive.> it has password protection and hardware base encryption.
