Bitlocker error 0x80070057


New Member
Initialized bitlocker on a removable drive. Completed. Rebooted.

Log on, put in password for drive. That works.

I can't access the data on it. Clicking on the drive prompts to format the drive (Do you want to format this drive?" (No, I have data on it silly!)

When I try turning off Bitlocker in the control panel, it comes up with the error "The parameter was incorrect"

Under CMD (Run as admin), manage-bde -off <drive letter> has the error:
ERROR: An error occurred (code 0x80070057):
The parameter is incorrect.

Help? I have data on this drive I need.
