I have always just connected whatever hard drive - or flash drive - to the pc (windows), right mouse click on the drive and select format. You have various format options (FAT, FAT32, NTFS, etc) You can select quick or full format. "Quick" doesn't delete or format every sector on the hard drive - it merely erases the headers on whatever info is on the drive so it appears empty, making it a very quick and easy process as whatever info there was is now "lost" (with the right data recovery software you can recover the formatted information). After that I just copy and paste whatever music (or movie) files to the drive and plug that into the av system or bdp-1 on the stereo. I prefer NTFS as that format reads a single file of 4 gigs or more - perfect for storing and watching huge mkv / bluray movies off a drive.
