But it works fine if I hook up USB. Some write ups say that you need an esata dongle for it to work. All the esata dongles I can find are USB to esata. My case, NZXT M59 has a front esata port. It is hooked up to one of the red sata ports on the MB. I also got a sata to esata cord to hook direct from the board to the unit, and neither of them will show the drive. Hook up USB and instantly the drive is recognized. Any ideas? TIA!! Jim.
