I got notice input, output error, when try to make a partition or try anything with disk utility

Use disk utilities from the Mac OS installer to format the new drive in a Mac format. Then install the Mac OS. New drive won’t show up in the installer until it’s Mac format.
A small pointer for any who have the same issue. I put in an entirely new 2TB WD sata drive and then preformed a fresh install of snow leopard onto it. When I got to the section to choose which drive to install to there was no drive image.
I clicked at the top on disk utility, then picked the drive, clicked erase and erased the drive. THis actually formats it into a mac format. after this I closed disk utility and voila the drive was now visible and installation could commence.
Good luck
