Assuming all of your regular stuff is covered ie* Drive has power and is connected. There aren't too many variables. I had the same problem but it was because my motherboard sata was not good enough by default I had to pick up a sata to pci adapter made by "via" After installing the drivers for that hardware It was able to detect. Make sure you check the flash tut first apparently some default sata drivers don't get along with the lite on's. Make sure you're getting your dvd drive turned on before turning on jungle flasher too in case jflasher is just being glitchy.
