Free data recovery - lost and raw data

I’m not sure how this happened, but I went to plug in my external WD My Book hard drive and it only showed like 32 GB and it is a 1 TB. I was able to detect that there is lost and raw files and the hard drive has partitioned itself. How, when, why? That is what I would like to know, but there is a large amount of files on the lost/raw files that I can preview that I need. Is there a free data recovery software/company out there that would be able to help me?

Currently, WD does not have a data recovery software.

Online you should be able to find a data recovery software like a free trial that might show you your files.

FILERECOVERY is one such program, designed to recover on hard drives. It is available for both Windows and Mac OS’s. It does have a free evaluation, so you can install and scan the drive to see if the data you want to recover is recoverable.
