I have a server that right now has a 160gb Seagate hdd "SATA" drive in it running Windows 2003 Advanced server. I want to add another identical 160gb hdd and mirror them in case one fails. I went to do this and it says must make it a dynamic drive is this correct? I do not want to loose any data on the current hdd.

How do I add this 2nd hdd on and mirror it with no issues?

Thanks for the help.

If you wish to use Windows server 2003 built-in Raid functionality then you do not need to do anything in the BIOS.

You can do this by following the steps given here: http://support.microsoft.com/kb/323432

One word of caution is that doing a mirrored set this way is completely software based and will draw on your CPU for all of the work hence it is naturally slower than doing this with a dedicated hardware controller.
Get your facts first, then you can distort them as you please.
