Q: trouble with external hard disk

Hi, I have recently purchased a new mac book pro (2,5 GHz Intel Core i7). My hard disk (Seagate SDR00F1), doesn't be recognized from the computer. In my old Mac book pro was recognized. Someone could help me to sort out this big problem? Thank you

MacBook Pro with Retina display, OS X Yosemite (10.10.5)

- Is the drive self-powered, that only powered by the USB bus? If so it could be that the USB port does not provided enough power. You can try a powered USB hub. You can also get a USB pigtail that takes power from to USB ports to the single USB port on the drive.
- Does it show in Disk Utility?
- Does it show in System Profiler under USB? You should see the chipset in the enclosure as well as the HD itself
