Not sure if this is the appropriate forum...
I have a dedicated drive used just for data. The entire drive is encrypted with cryptsetup & LUKS. Since the drive is 3tb in size I had to create the partition with parted. The partition is aligned for optimal performance.
| Code: | WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted.

For some reason, every time I reboot the LUKS header is no longer recognized. I checked to make sure the appropriate modules are loaded into memory. The first time I just redid it thinking maybe I did something wrong. The second time now this has happened I'm thinking something else is going on. Why does this keep happening? How do I fix it without redoing it as I have data on this drive.

Device /dev/sdb1 is not a valid LUKS device. |
