I have an Intel Core2 Duo iMac5,1 and I am trying to install a new hard drive. The disk I bought is a Seagate ST1000DX001 (1TB hybrid drive). I installed the disk, booted from the original install DVD and ran Disk Utility. This is where it gets weird. Disk Utility sees the 1TB disk as a 7.3TB disk. It correctly identifies the name as ST1000DC001-1CM162, however. When I select the "Partition" tab then the default size for a single partition is 7.28TB. I can't change this (I can, but it changes itself back to 7.28). Of course it also won't partition or erase it if I try (fails with input/output error). System Profiler also sees the correct model but incorrect capacity. Have you ever seen this before? Could it be a bad drive? Thanks, Dave.
