WD Passport won't retain files

I have a 1TB WD Passport. I’ve had it for about a year and it hasn’t given me any problems until the last couple months when it wouldn’t play some files on my WD TV. I figured out that those files showed Zero KB in their file size. I tried transfering those files to my Passport again and they showed the correct file size. But when I plugged my Passport into my WD TV Live, they wouldn’t play and when I checked again on my computer they showed Zero KB again.

What could be making my Passport spend the time transferring files and showing correct file size and then showing Zero KB file size later? Could the WD TV be doing something to the files?

I don’t think that the media player is deleting the files from the drive… :confounded:

Are you able to write zeros to the drive and create a new partition to see what happens?

Also just in case. please set the media player back to factory defaults.

Thanks for getting back to me. I don’t know what “writing zeros” is.
