Have also tried unsuccessfully to use Data Rescue but their instructions call for connecting to a FireWire drive and I've now discovered that there seems to be a problem with my FireWire port which I've never used before. A technician for Disk Warrior (I don't own their product) gave me some instructions for solving the problem with Terminal which have also failed so far to work.
What are the instructions they gave you?
I would be incredibly grateful for advice that will help me get my files back.
Well, it's likely to be expensive, but a disk recovery service like Drive Savers <http://www.drivesavers.com> might be able to help you here. (MIGHT, I don't know that they're any more well equipped to handle this than anyone else.)
The problem, alas, is FileVault (I like that VileFault moniker.)
I described it to another victim on another list as:
"Putting all your eggs in a nearly rotted out basket strung from a power line over a busy interstate with frayed twine, in high winds.
With hail predicted.
Baseball sized hail."
Unfortunately, the very basis of FV makes it susceptible to these issues.
This is a neat technology that requires operational perfection, and is horribly horribly fail-unsafe in practice. Flip one bit in the encrypted image and *poof* your home directory is gone.
I would only ever recommend FV if your system is backed up daily and EVERYTHING on the disk is sensitive or confidential. The NSA likes FileVault <http://tinyurl.com/3opov> but they'd rather lose the data on the computer than have it be compromised. Most users want more emphasis on data retention over security.
If you need to keep materials on your hard drive secure, I suggest creating encrypted disk images using disk utility and storing just the sensitive materials there.
This allows you to manually mount and dismount the disk images, (bear in mind, that any images still open during a crash will be unchanged, since changes to disk images aren't written until they're closed.)
