So I have a car stereo that has the capability to play music from a portable hard drive. When I first got the hard drive it didnt work in it so i had to format it so the stereo could read it. After adding music to it everything was fine. It played all the MP3 files and a few other file types that I had on the drive. Some time later I cant really tell you how long I reset my CPU because I had installed an SSD to run my windows. After doing that for some reason a big chunk of the music I had on the portable hard drive doesnt play in the car but I can easily find it and play it on my PC. I even added newer songs to it and a chunk of those songs will not play on the stereo. Does anyone know what the problem could be and please tell me it does not consist of wiping this entire drive because there is a huge collection of files on here that I dont think would be able to copy onto my computer or somewhere else unless I buy another 2TB...
