thank you, I ended up usinghttp://support.ts.fujitsu.com/IndexDown ... 2D8D718ED1
on a windows 7 machine on the LAN
was quite easy to connect.
I was advised by Fujitsu support the my server supports 24 drives, I have not checked the internal cables yet, but will order the 2 drives and hot plug them and see if all is ok or not. reasonably confident it will all be fine. thanks for your assistance.
