Correct procedure to replace failed drive in Windows 2003 software RAID1 (mirror)?

I have one disk of a Windows 2003 Software RAID 1 (mirror) showing errors.  I plan to replace the drive as Disk Management reports 'Failed Redundancy' and all attempts to bring either the disk or volume back online fail.  

What is the 'best practices' or 'proper' procedure to replace the failed disk?  (i.e. - break mirror, remove drive, replace new drive, re-initialize mirror...?)

Thanks for your feedback!

Essentially, the proper procedure is what you just described:

1.  Break the mirror.
2.  Remove and replace the failed drive.  When you bring the system back up, you may still see the old (failed) drive listed, because it can leave registry entries behind.  If so, you'll need to delete the old failed drive.
3. Create a new mirror between the remaining operational drive and the new drive.

I would also first make sure that you have a good backup of all data/programs just in case of the worst case scenario where the remaining drive fails before you get your new mirror created.

I just needed confirmation from someone on this  - thanks.  Also, good info about the remnant disk entry in Disk Management which will need to be deleted.
