Yes, i did say i had drivers but after reading the posting that was provided by Submix8c, there appears to be different drivers applying to different chipsets i.e. NF4-7 or MCP73. Hence the new question about how to determine what chipset i have, i do thank you for the link to the HP site but that just lead me to the drivers for the chipset which i already have. I just need and want to make sure i have the proper SATA drivers for the chipset i have.
