I just bought a Kenwood KDC-X590 and a Seagate 40GB HD. Here's the rundown on specs: Windows XP FAT 32 Format on HD 40GB (37.5 actual) The instructions say that when you connect the HD via USB, and start up PPM (Phat Music Manager), PPM will recognize the HD and you can drag and drop your files. Well, PPM isn't recognizing my HD but my desktop is. Any clues?
