This eBay listing is for ONE Sony DRX-840A External  USB DVD/CD Rewritable Drive Burner. Used and in perfect working order, Slight cosmetic scuffs on the silver painted enclosure but nothing major. This was my own external drive from years ago, I used it only a handful of times... Other than that, It just sat in the closet. The 12V power supply is missing but they are available here on eBay for as little as $10. I did test it with my bench top power supply and it is in working order. I will give it my own 30 day No DOA warranty. Buyer pays $12 S/H via USPS priority mail. Buy with confidence from Esoteric Specialties!
