(Windows 2003 R2 software Raid mirror 2x SATA HDD 160GB) I have a problem. I removed 
a faulty mirrored Dynamic drive in software  thinking I didn't need a "missing Disk 
0 failed redundancy HDD".
 It wasn't avaliable in "system manager" so OK it's a DUD hdd..... I  removed it 
by taking it out of the Disk management and was going to modify the "Boot.ini". (See 
Below) before rebooting the server.

***************************************************
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003, Standard" /noexecute=optout 
/fastdetect
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Boot Mirror C: - secondary plex" 
************************************************************************
What I need to know for editing the "Boot.ini" is.... Can I just delete the bottom 
line??? 
Do I need to change the rdisk(0) to rdisk(1) if the "Disk management" (in Computer 
management) says at the moment the working drive is labeled as Disk 1 or will it 
change after I reboot and become 0 so rdisk(0) is OK??

Also "AFTER" I had removed the drive in Disk management I read a Microsoft white 
paper that has warned not to break the mirror and remove the copy of the drive (See 
below below). What should I do???

Thanks!!

Missing dynamic disks
If Disk Management shows a missing dynamic disk, this means that a dynamic disk that 
was attached to the system cannot be located. Because every dynamic disk in the system 
knows about every other dynamic disk, this "missing" disk is shown in Disk Management. 
Do not delete the missing disk's volumes or select the Remove Disk option in Disk 
Management unless you intentionally removed the physical disk from the system and 
you do not intend to ever reattach it. This is important because after you delete 
the disk and volume records from the remaining dynamic disk's LDM database, you may 
not be able to import the missing disk and bring it back online on the same system 
after you reattach it. 
Text-mode setup and Recovery Console
Never delete or create a partition on a dynamic disk during Windows 2000, Windows 
XP, or Windows Server 2003 text-mode Setup or when you start the computer by using 
the Recovery Console. If you do so, permanent data loss may occur. For more information 
about this issue, click the following article number to view the article in the Microsoft 
Knowledge Base:

Dynamic Unreadable in Disk Management 
The mirrored drive
Never break a healthy system disk or boot dynamic mirrored volume and expect the 
mirrored drive to replace the original primary drive if it fails. The manually broken 
mirrored drive is assigned the next available drive letter, and this is updated to 
the permanent record in the LDM database. This means that regardless of what position 
that drive takes in the boot process, it is assigned the new (and incorrect) drive 
letter, so the operating system cannot function correctly.

Note Windows software mirroring is a fault-tolerant solution that makes sure you 
can maintain access to data if you have a hardware disk failure. Software mirroring 
is not intended to be used as an offline backup mechanism.
