I have a "My Passport" extrenal hard drive originally formatted for use between mac and windows machines. I'm not sure but I think it was FAT32....could be a different one but it worked. Recently I only been using it in my windows 10 machine. No problems, then all of a sudden my PC will not access it giving me a message to format the drive. I know my data is still there because I can access movies files and see the folders on my smart TV via USB. I have some files on there that are important to me and don't want to format it before at least trying to get my data off the drive. Is there a way to transfer the files before formatting? Thanks in advance.
