My Passport 750 GB External Hard Drive Not Showing Files

I’ve had this since 2010 then around August 2012, the files failed to show up whenever I would plug it into my laptop.

The capacity is about 750 GB and it says the available storage is 452 GB. So, it says the space is being used but I have no idea how to bring up my files again. I just want to transfer all of the files out of there before it dies for good. 

If anyone knows any possible free solutions, please let me know. I’m desperate.  

Hello,

It is possible that the partition is corrupted and thats why you dont have access to your files.  It may be possible to extract the data utilizing data recovery software. There are several kinds of Data Recovery software available. If you do a web search for Data Recovery it will yield plenty of data recovery software options.
