1: As leew said: Move data away from C:. Do not use third party tools, it rarely works.
2: Just replace the drive and activate th Raid again.
3. Use SBS backup for a full and easy BU. To restore just install server 2003 from disk1 and do a restore. Works a treat.
Hope that helps,


Yes, it has 12 GB, I did move already sharepoint, and I am planing to move exchnage.

Be carefull with software Raid. At least you can remove a drive and still have a working system with one drive only.

You can't extend/increase the size of C: without third party software or a reinstall.  I do not advise this.  Why do you think 12 GB is too little?  Most of my clients run SBS servers and of them, most have C: drives of 12 GB.  Further they all have at least 3 GB (some as much as 6 GB) free because I have them setup properly.  I've given you instructions for resolving your issue.  If you insist on resizing, you are taking a chance AND spending money unnecessarily as you will need a server compatible resizing software which is typically going to cost you $300.  And then you have to hope it supports Dynamic Disks. Since it's a RAID 1, just pick a point in time and break the RAID.  Then you'll have two identical drives with your data.  resize ONE of them and then rebuild the RAID.  


I think you are right leew, I was call to a place, and this is the set up I found, broken software Raid 1, 200 MB on C drive. Now,  where should I start, fixing  software Raid 1 or moving data from C to D?
Move Data first.
