I can't unlock My Book (after reseting my computer) even though I know the password!

Yesterday I reset my Windows 10 laptop to factory settings. It was getting old and tired and now it is like new. But I have a colossal problem now. My computer refused to reset while keeping my documents intact. So I told it just to delete them and do the reset because I had all the important stuff I wanted to keep on my external drive. I was just going to put them right back on after it was done with it’s process. I plugged my drive into the computer today and it wont let me unlock it now! I know the password for certain but it wont budge! I can’t just reset it and lose all my data. I don’t have it stored any other place because the My Book was my backup. Help! Does anyone have any suggestions. I have been researching this all day and it looks pretty bleak. Please, someone tell me there is something I can do. This is maddening, the files are there and I know my password, yet everything seems hopeless.

Hello,

Did you try using lower or upper case letters for the password?

In case that you are not able to access the drive, see the following link for additional information.
