I had 4 hard drives that I put in to my new computer and wiped them individually using the cipher command in Windows 7 and then formatting in the windows explorer. They all worked prior and I could drag and drop files after.
I'm trying to install Mac OS X Leopard on to a 6 year old Mac Pro that worked prior to having its hard drives removed. I inserted the hard drive, inserted the installation CD for Leopard, and booted from CD, but it just hangs indefinitely.
It sounds like the disk is being read but the monitor never displays a picture. I tried 3 different monitors (that all work with other computers) and both the DVI ports on the Mac Pro but the monitor keeps saying there is no input data to be read from the computer.
I'm not sure why this is happening. I had just recently used the computer until I had gotten my new computer and it worked fine but now it doesn't seem like it is sending any picture data to any monitors and I can't reinstall the OS as a result. I'm not sure if I can install MAC OS X on another computer and then reinsert the hard drive because this is our only MAC.
