Taking 14secs. FORMATTING this external hard drive to 'FAT32' and then spending an additional 3mins. CLICK-N-DRAGGING 125GB of .mp3 files to the drive (usually auto-assigns itself to K:) with the 3.0USB cable (that COMES WITH IT!) and I got ALL my music to compatibly play through my truck's CD deck, and my entertainment center's audio receiver through the USB slot. NO MORE LUGGING AROUND 100'S OF CDs! Enough said. Also, you could back-up your ENTIRE computer if you fancy a COMPLETE motherboard restore in the future! (1 last thing!): WARNING WARNING!!!!!:: Be RIDICULOUSLY careful handling/transporting these around! For REAL, listen to me. Accidentally dropped my last one out of my hoodie front pocket on the RUGGED floor from only 3ft. above ground and it cracked the internal disc making it useless and me frustrated/bewildered/$50 poorer to get a new one!
