SlickWilly 0 Posted September 14, 2000 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? Share this post Link to post
Bursar 0 Posted September 14, 2000 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. Share this post Link to post
gramaglia 0 Posted September 19, 2000 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? Share this post Link to post
MoreLight 0 Posted September 20, 2000 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] ID: Q141702 CREATED: 21-DEC-1995 MODIFIED: 20-JAN-2000 WINDOWS:2000; winnt:3.5,3.51,4.0 WINDOWS winnt PUBLIC | ntsetup ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 - Microsoft Windows 2000 Server - Microsoft Windows 2000 Advanced Server ------------------------------------------------------------------------------- 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.
