Mirrored Drives - Broke Mirror - Now got problem

Hopefully someone can help me. We had our PDC at the office set up with two identical SCSI drives, set to software raid 0 (mirroring). Tonight I was going to upgrade to Windows 2000, and in preparation, I broke the mirror so we could keep the second drive as a backup in case anything went wrong.

Hopefully someone can help me. We had our PDC at the office set up with two identical SCSI drives, set to software raid 0 (mirroring). Tonight I was going to upgrade to Windows 2000, and in preparation, I broke the mirror so we could keep the second drive as a backup in case anything went wrong. Well, it went wrong. Naturally. Now I can't get the secondary drive to boot up even if I set it's scsi id to 0 (the way the other one was). I booted into Dos mode with my Windows 98 CD-Rom and ran fdisk, fdisk report partition 1 as an unknown file system, and partition 2 as FAT16. Both are supposed to be NTFS. Any ideas how to fix this?
 
Also, are there any command line editing tools that can access NTFS under a dos or similar environment?

Unfortuantely, you cannot access NTFS from a DOS command prompt.
 
FDISK will show the NTFS partition as Non-DOS, so don't worry about that bit too much.
 
It might be worth checking the SCSI termination on the drive. If it has come out of a SCSI chain, it might need changing.

Currently, I know there is a detailed procedure on the Windows NT Resource kit that tells exactly how to resolve your problem, but I have no more this book, that was lent to me by a friend and I can't remember it. Guys out there, is there anyone that has the Reskit books?
I'll search for it meanwhile, ok?

Ok Willy here is some info. It is for IDE mirrors, but you may be able to apply it to SCSI. Its a long one so hopefully no one reams me for this. Just trying to help.How to Recover Mirroring Windows NT Using IDE Devices [ntrelease]

SUMMARY
=======
 
This article provides the steps necessary to recover mirroring using IDE devices
under Windows NT. Use this article in conjunction with the following articles in
the Microsoft Knowledge Base, which explains how to create an Windows NT Fault
Tolerant Boot Disk:
 
ARTICLE-ID: Q119467
 
TITLE: Creating a Boot Disk for an NTFS or FAT Partition
 
ARTICLE-ID: Q102873
 
TITLE: BOOT.INI and ARC Path Naming Convention and Usage
 
Soft Mirroring (Windows NT) does NOT mirror MBR/PT entries, as soft mirroring is
only designed to mirror a partition's data, and cannot guarantee boot capability
of the shadow, or mirrored drive. It is important that you always have a valid
Windows NT fault tolerant startup floppy disk created in the event that the
primary drive fails.
 
ARTICLE-ID: Q117131
TITLE: Master Boot Record Not Written To Mirrored Shadow Partition
 
MORE INFORMATION
================
 
The IDE specification requires that a working master drive be available at all
times to gain access to other IDE drives on the system. The steps that follow
are the appropriate steps to mirror an IDE hard drive with another.
 
Step-by-Step Procedures
-----------------------
 
If the shadow (mirrored) hard drive is on the same channel set as an IDE slave
device, use the "Failed Primary on the Same IDE Channel" section of this article
below.
 
If the shadow (mirrored) hard drive is on the secondary channel across from the
failed primary drive then see the "Failed Primary is on the Primary IDE Channel
and the Shadow is on the Secondary" section of this article below.
 
FAILED PRIMARY ON THE SAME IDE CHANNEL (SHADOW DRIVE IS A SLAVE IDE DEVICE)
 
*** If the replacement drive has already been installed: ***
 
1. Edit the Boot.ini file in you Windows NT FT startup disk to point to:
multi(0)disk(0)rdisk(1)...
 
2. If the replacement drive is not identical to the failed IDE hard drive, you
must go into CMOS and use either the AUTO DETECT HARD DRIVE feature in your
CMOS, or manually set the new hard drive Heads/Cylinders/Sectors.
 
3. Start the Windows NT FT startup disk and load Windows NT.
 
4. Start Disk Administrator, and break the mirror.
 
5. Establish another mirror by mirroring from the slave hard drive to the master
drive.
 
*** If the replacement drive has not been installed: ***
 
1. Verify that the jumper on the shadow IDE hard drive is moved from Slave to
master or standalone.
 
2. Edit the Boot.ini file in the Windows NT FT startup disk, to point to:
multi(0)disk(0)rdisk(0)...
 
3. If the shadow drive is not identical to the failed IDE hard drive, you must
go into CMOS and use either the AUTO DETECT HARD DRIVE feature in your CMOS
or manually set the new hard drive Heads/Cylinders/Sectors.
 
4. Start the Windows NT FT startup disk, and load Windows NT.
 
5. Start Disk Administrator, and break the mirror.
 
6. Establish another mirror by mirroring from this hard drive to the new shadow
(IDE Slave) drive.
 
Failed primary is master the on the primary IDE channel and the shadow is master
on the secondary IDE Channel
 
***If the replacement drive has already been installed:***
 
1. Edit the Boot.ini file of your Windows NT FT startup disk to point to:
 
multi(1)disk(0)rdisk(0) if the shadow drive is the master device of the
secondary channel multi(0)disk(0)rdisk(2) may also work
 
multi(1)disk(0)rdisk(1) if the Shadow drive is the Slave Device of the
Secondary Channel Multi(0)disk(0)rdisk(3) may also work.
 
2. If the replacement drive is not identical to the failed IDE hard drive, you
must go into CMOS and use either the AUTO DETECT HARD DRIVE feature in your CMOS
or manually set the new hard drive Heads/Cylinders/Sectors. 3. Start the Windows
NT FT startup disk and load Windows NT. 4. Start Disk Administrator, and break
the mirror. 5. Establish another mirror by mirroring from the this hard drive to
the new Shadow drive.
 
***If the replacement drive has not been installed:***
 
1. Move the shadow drive to the primary channel as the master device and ensure
it is jumpered in the same manner as the failed primary drive.
 
2. Edit the Boot.ini file in your Windows NT FT startup disk to point to:
 
multi(0)disk(0)rdisk(0)
 
if the shadow drive is the master device of the primary channel.
 
multi(0)disk(0)rdisk(1)
 
if the shadow drive is the slave device of the primary channel.
 
1. If the shadow drive is not identical to the failed primary IDE hard drive,
you must go into CMOS and use either the AUTO DETECT HARD DRIVE feature in
your CMOS or manually set the new hard drive Heads/Cylinders/Sectors.
 
2. Start the Windows NT FT startup disk and load Windows NT.
 
3. Start Disk Administrator, and break the mirror.
 
4. Establish another mirror by mirroring from this hard drive to the new shadow
drive.
