I have followed a guide to set up the core storage logical volume to use one SSD and one HDD.
Since then, I have encountered multiple errors such as:
69822 Couldn’t rediscover disk after operation
69780 Unable to create a new CoreStorage Logical Volume
When created my Fusion Drive, I inverted
disk0 (HDD) and
disk1 (SSD) in the first command to create a Logical Volume Group.
If I boot normally (not in safe mode), the machine hangs at Apple logo ... even if I try to boot from an external drive or a Mountain Lion startup drive.
Could this be a problem of the EFI version (2.7)?
Hardware: Macbook Pro 15" early 2011 (8,2)
