Do you have access to a second Mac? If you do you could try starting yours in target mode and use the other to install the OS via a FireWire, USB or Ethernet back to back cable.

"Same problem except that I am a 25 year Macintosh consultant and this has me stumped, I can use Data Rescue to see and recover all the files I need.

The two drives that have the lock on, are internal macpro drives this happened four days ago.

I did not do it

I am fully aware of all of the ways to change permissions on the drives They all have a custom permission and when I try to change it to specify a user or admin as read and write they all go back to custom, and Yes I unlocked the get info before I tried.

My Data Rescue Program says that the data was changed 2/5/40 ""I say what the""

This is the message that I get after running data rescue

@@@@HFS+ Private Data 2/5/40

The previous date was 2/10 2015 before the message above

I have also used the terminal program to try and access and unlock the drives I do not have the code at hand at this moment

Just another friggin Apple problem, that probably has no solution.

sometimes I wish they would fire all of the nerds that are now in place and hire back the old ones. At least they the old ones had caring about users in mind they tried to solve problems instead of creating them. The New Yosemite and Lion and Montain Lion and Mavericks have done nothing except mess with older computer users and the programs that no longer work. Now all we have are a bunch of I phone idiots walking out into the streets with their eyes glued to their %#*@ phones.

"Just boot from the lion, use terminal window to run the unlock command of the logic volume.

Follow the procedure in this blog

After this format the drive with non encrypt format, then you good to go."
