On version 5.1.8, getting the above listed error. The encryption had been working for many weeks prior, and then the error started showing up. Using the Wintech CD and the .sdb file, we still cannot access the data. We can see the c: drive, but not read it. Is there anything else to be done, or is the machine toast? Also what could have caused this particular error to start appearing after functioning normally for a while?
Did you inspect disk partition table, OS boot partition sector, disk sectors encryption?
Does it prove that used SDB is valid for this HD?
