Wave Systems Trusted Drive error when trying to login past hard drive pasword

When trying to login through my E6400, I am all the sudden getting an error saying: "Status=6a88 referenced data not found". What does this error message mean? I cannot find anything on this. I ran Seatools diagnostic both short and long and both passed. I was using the laptop, left it for a while and it went to sleep. Went to power back up and login and started getting this error. I have pulled the battery and reseated the hard drive to no avail. This is for my work and my work IT has no clue. I DO NOT want to lose data. Any help would be appreciate. This is on a seagate FDE hard drive.
