Then, I tried to create a volume of type "Mirror" on the D drive. It would finally allow me to choose the mirror option in the create volume window whereas that option was grayed out before.
Interestingly, while it would let me create a mirror volume, it would only let me create one 7MB in size. I'm guessing that since the mirror was broken on the original two drives when a replacement drive was added to the system after the crash of the original C drive D became C and the replacement drive became the current D drive that there is some remanant mirror information on the current C drive that is preventing me from creating a mirror volume on D that is the same size as the volume currently taking up the entirety of the C drive.
In simple terms, since I low-level formatted the D drive the "add mirror Also, the option to create a mirror volume on D is no longer grayed out since the low-level formatting of the D drive. But, I can only create a mirror volume on D that is 7MB in size. Is there some way to fix this so I can create a mirror volume on D that is the same size as the volume on C there is only one volume on C which is about Confused yet?
Thanks, in advance. Most definitely, yes. I did a low-level format of the D Drive that wrote zeros to every sector on the hard drive. Completely wiped it. Then I went into the Disk Manager and re-actived that disk. I right-clicked on the unallocated space and chose "New Volume" and got a new window prompting me to choose which kind of volume I wanted. I chose mirror. I then takes me to a series of screen that is asking me to choose which two disks to mirror. I chose C, as D is already listed as one of the disks.
At that point the it only allows me to create a 7MB mirror volume. It's like it's looking at the C drive, seeing that it has a volume that already has a mirror associated with it the broken mirror from when the original drive failed and then it says "Well, you can't use that volume on C. I'll just give you an arbitrary 7MB that happens be left at the end of the C drive to mirror onto the D drive.
The C drive only had one volume on it that took up the whole disk. It was being mirrored onto the D drive. The C drive crashed and a Dell tech came out and moved the D drive into the primary master disk position C dirve and then intalled a new drive as the D drive. He then "broke the mirror" and packed up his gear and split. Dell does not support software raid.
So, that is what I'm left with. A C drive that was the old D drive, and a new D drive that won't allow me to create a mirror volume of more than 7MB. Does that make sense? Take the D: Drive back to an "unallocated space" state and use the following instructions to create the mirror I followed the instructions to the letter a few times.
One thing: I ran the diagnostic software that the hard drive manufacturer puts out and it said that Disk0 is failing. So, I got a brand new drive sent to me from Dell. That's my day, today I'm going to try and clone the C drive to the D drive, move the D drive into Disk0 position, hope that it boots correctly, install the brand new drive into D position, and see if I can mirror it then.
The resulting Add Mirror dialog will list the disk drives available on the system. Select the desired disk in this case disk 1 as shown below:. With a suitable mirror disk selected, click on Add Mirror to begin the resynching process. During this phase the operating system will copy all the files from the original system volume including System, Boot, PageFile and Crash Dump to the mirror disk. It will also create the master boot record MBR. Finally, Windows will add the mirror as a secondary boot option in the Boot Manager such that it can be selected when the system is rebooted.
The system and boot volumes on an MBR disk may also be mirrored from the command prompt using the diskpart tool. Begin by listing the disks attached to the system using the diskpart list disk command:. In the above output disk 0 is the current system disk and disk 1 is the disk to be used as the shadow system disk. If the disks are not yet dynamic they need to be converted before the remainder of the mirroring set up and can be completed:.
Next, we need to select the system volume on disk 0. To obtain a list of volumes, select the disk and use the list volume command:. In the above example the system volume is listed as Volume 0.
This will initiate the resynching process which may take some time depending on the size of the system volume. When a list volume command is run during this process, the volume status will be listed as Rebuild until the resynching is complete:. When the Status changes to Healthy the mirroring is complete. Next time the system is rebooted the mirror will be listed in the boot menu as Microsoft Windows Server - secondary plex. Here is an example from forum. I want to buy a second hard drive and mirror the entire system drive over including all partitions.
Is this possible or is it impossible to mirror the system drive? Also, I know I need to convert both discs to dynamic volumes before this could possibly happen. Will I lose any data converting my basic disc to dynamic? Thank you. Here you will learn two methods to mirror hard drive in Windows Server The first one is to use "Add Mirror" feature in the Disk Management to configure mirroring in Windows Server step by step. To make this task run smoothly, you need to conver the system disk to dynamic disk first.
It allows you to clone disk to larger disk and clone larger HDD to smaller SSD as long as the use space on old disk is equal to or smaller to the target disk. To mirror disk to disk, you need to prepare a second hard drive and initialize it with Disk Management.

This step-by-step article describes how to mirror the system and boot partition in Windows Server This scenario is based on the assumption that the system and boot files are located on disk 0 and that disk 1 is unallocated space. The memory dump file is written only to the boot hard disk. Windows Server can continue to work with a mirrored system disk configuration even if one of the disks in the mirror is removed.
However, the memory dump file cannot be written to the remaining system disk in the mirror.
