Encrypt Whole Disk fails

Created: 26 May 2011 • Updated: 26 May 2011 | 1 comment

I'm attempting to encrypt an external USB hard drive using PGP WDE for Mac 10.1.1. The disk has been cleanly formatted as a Mac OS X Extended volume, and passes checks in Disk Utility. Whenever I begin the process, PGP gets a few hundred megabytes in and then fails, ejecting the disk in the process.

Here's the relevant log output:

2011-05-26 20:48:20:	Switched logging level to Debug
2011-05-26 20:49:29:	-[CPGPWDEController (0x16E16730) addUser:toWholeDisk:withPassphrase:admin:] Adding user to whole disk

What would be causing this and how do I fix it?

1) Make sure that it's been partitioned as GUID (not just erased).

2) Disk utility isn't a reliable indication of drive failure - you may be hitting bad sectors.

3) If it's a pre-built unit, many of them have hidden/virtual partitions that show up as additional volumes or virtual CD's.  Those are generally incompatible with PGP, and likely cannot be removed, just hidden.
