How to get to my files I already have on my WD My Book

I have an older WD My Book ( more than 5 years old ) I wanted to start using it again and I am not finding the files that I already saved on the device. From what I am reading I am not even sure my device will work any longer since the company is talking about MyCloud Storage etc. So since my machine is more than 5 years old. ( I can’t even update the software ) Is it just a paperweight now?

You may use data recovery tools to recover the important data files which are no longer showing from My Book.
However, WD Drive Utilities can be used to check the health of My Book which helps to know whether you should continue to use My Book or not.
