I have an intel Mac mini whose hard drive (60GB) appears to have failed. It would not boot and could not find boot information so I used the disc utility and every time I tried to reinstall OS X it would fail. So I went and bought a 500 Gig Toshiba drive but when it comes up in the Disc Utility it shows up as a 3.6 TB drive. It fails when I try to do a Disk erase and format, and I can't seem to get it to work. Could it be something in the hardware of the mini has failed or might I have forgotten something while putting things back together. Any assistance is highly appreciated! Thanks
