I have been having a lot of issues with my Ford Sync giving me "bad media" error messages. I have come to find out that this is caused by SL putting a "._filename.MP3" file for every MP3 I copy over to either my ipod or my USB drive. When using a USB drive, I can plug it into my windows machine at work and delete these files off, and it works great. But how can I stop this from happening? I would like to use my ipod in the car, but I cant delete the ._ files off. I also can't see these files in SL when I show hidden files... For those of you that dont know, Ford Snyc is developed my Microsoft and allows you to hook up a USB MP3 device to the factory radio. The USB drive is formatted FAT32.
