I recently purchased a used Precision 370 Workstation with 1 HDD, and wish to install a 2nd HDD and activate Raid 1.  The computer has a 3 ghz. proc, 2 gb. ram, 40 Gb Hdd.  Running XP pro.  Is it possible to activate Raid 1 at this time, without losing all the data on the original drive?  If not, after adding the 2nd drive, can the OS be reinstalled with the CD I got with the system (Reinstallation CD, XP Pro SP2) ?

Thanks.
