I encrypted my external hard drive and save the recovery key to a thumb drive. Now I cant access my external drive. I get an error message that says that the key I have entered does not match this drive. Can anyone help?

Hi harvey,

You should use password first.

If you forgot your password for decryption, you could use your recovery key for recovery. If you mean the error message says that the recovery key you entered does not match this drive. Make sure you enter the right key and txt file has not been modified before because error shows that you entered the wrong key.

If the recovery key doesnt work, bad news, Im afraid that you have to wipe it out.

Regards
