I have a 4 TB WD my book external hard drive, I use it about once a week to save the recordings I make but recently it has stopped working. I plug it in and it takes a really long time to find the drive and then opening files takes forever too, sometime the folders won't even open and i will get an error the says "G:\Path" not accessible Device not ready even if I manage to get to a spot where I want to save a video when I try to transfer the file it transfers a bit and then it has an error where it says that the place I am trying to save to doesn't exist and then I can't explore my hard drive anymore. Is there a way to fix this or do I have to do something drastic like reformat?
