I have an encrypted 2TB Seagate external hard drive which I've been using for the past 1-2 years with no problem. A few days ago while in use, the hard drive turned off. I plugged it back in, my macbook recognised it and it asked for the password. After entering it, the window turns grey for 1-2 mins and then shakes as if the password is incorrect. I'm 100% sure I'm using the correct password, so I opened disk utility and used the repair disk function but it says it can not be repaired. Do I have any other option to recover the data?
