|Is it a 3TB (or larger) hard drive with GPT formatting? |
The hard drive controllers on many older computers don't know what to do with GPT disks. I ran into this problem when I installed a single-partition 4TB GPT drive in my HTPC. It froze during the hard drive detection phase of POST. I eventually got it to work by making two 2TB MBR partitions with GParted.
