I have a filevault2 disk with two partition. One is the boot partition, the other contains data, both are encrypted.
Today, after installing the latest 10.8 update (10.8.4 I guess), the computer reboots, asks for the user password at EFI (filevault2) and starts in verbose mode as usual.
Unfortunately, the boots hangs with a line:
CoreStorageFamily::unlockVEKs() failed to unwrap the vek, status = e00002bc
I can boot in single user mode and execute
fsck_cs. The drive appears undamaged (so says fsck_cs) but again, the error message about the-said VEKs is printed on the screen. The second partition, the one that contains the data is the one causing the issue.
What can I do to get back my precious data ?
EDIT: It appears both volumes can be mounted as external disk from an other MAC computer. So, what's with the VEK preventing the system to boot ?
