ERP 6.0 - Disk Partition Size for Windows Server 2003 with SQL Server 2005

Hi Experts?

What is the recommended logical/phyisical disk partition size for:

1. ERP 6.0 All-in-One (FI,CO,MM) [Windows server 2003 and MS SQL Server 2005]

How many partitions should there be for each installation?

Also is it recommended to have the database software installed on a seperate

disk to the data and log files?

I have read the installation guides and cannot find this particular information.

Much appreciated...
