Did you download and install the HDD mfr's disk utilities to install the HDD to your system? Most have a utility pack that allows you to format and install the HDD.[/quotemsg
treefrog07 Thanks for your reply!!!
Following your idea I went to the Seagate site, whilst looking for the downloads I spotted FAQ-- checking this out, I spotted a question similar.
Long and short of it was, go to computer management, I did this and found that my new 500Gb disk was there, but had a partition set at, Yes 127Gb. the rest of the space was unallocated. I reformatted the whole disc and when
completed it showed the whole disc and "Healthy" 470Gb.
