I recently bought a new car, and the infotainment system has an onboard hard drive that I can load music files to using a usb drive. I tried doing this with my 4 year old iMac and with my one year old MacBook. I was able to get the files transferred to the cars hard drive, but when playing the songs, it skips. I tried it in multiple songs, and each one is like that. I tried using MP3’s and iTunes files, both of which the car can read. It happened the same way from each computer. I am suspecting the computer didn’t write the file onto the usb drive correctly. Any ideas of how to get the files onto the usb in whole would be helpful.
