Q: Disk Utility not formatting new internal hard drive

Thanks Allan Eckert for the quick reply. However, that's something I did and it doesn't get past "waiting for disks to reappear" when I try to partition the hard drive into a GUID partition scheme. I've tried looking that up, however, I have yet to find an answer of how to fix or get past it.

Tried that too, still not going past "waiting for disks to reappear"

Just returned it, got the new one and same thing happened...I'm pretty confused with this right now. I used it as an external hard drive and it formatted fine. I installed Yosemite on it and ran fine as the operating system as an External Hard drive. However, as soon as I switch i put it into my laptop, it does not pick up or read. I just formatted the hard drive again and trying to install it, but now it is giving me a different error "this disk cannot be used to startup your computer yosemite". It's actually running as my internal hard drive right now and that's is what my computer is giving me.
