Restore Master Boot Record on Raid Drive

Posted on 2014-02-25

Hi,  I would like to use Raid stripped array drives as Windows 7 64 bit volumes.  Is there a way to restore the Master Boot Record to the stripped array drives?
The formatting  of the Raid Array system deletes the MBR and installs a Raid Array file system.   Would you comment on using the Windows 7 install disc to activate the Recovery Console?

Is this software or hardware RAID?

The two sata raptor hard drives where originally a stripped array system.  I want to convert them to a standard NTFS file system and install a Windows7 64 bit OS.   I need to restore the Master Boot Record so that I can reinitialize and format the hard drives.

Ah, you want to clean up the drives simply to use them as standalone drives. Ok, clear now.
MBR is written to the HDD when you initialize it. To reinitialize the drives and remove the RAID info from them you need simply wipe the drives.
Use DBAN to wipe the drives. After the wipe is done as soon as you get to Windows disk management or run installation to the drive from Windows DVD it will initialize the drive and write the new MBR.
Or the simplest way for you is to do Update MBR from Windows 7 DVD:

Windows 7 disk management does list the raid drive on which I want to install the Win7 MBR.  It is listed as not initialized.  Disk management in not able to initialize the drive

I booted the Windows7 64 bit installation disk and tried to install the MBR using the recovery tools available using  the command prompt selection.

The tried the  commands "bootsect /nt60 SYS /mbr" and "bootsect /nt60 SYS ALL /mbr" .

I got this error:  "the selected device cannot be found".

I tried the command "bootrec /fix mbr"

I got this error: " the device attached to system in not functioning".

When the System Recovery Option window opened, the Operating System box was blank.

Also, Windows7 disk management listed the drive as 138 GB, which is the Raid 0 combined disk size.   The drive is a 74 GB drive.

I think your RAID controller has problems. Disk Management during initialization writes the MBR. If you are not able to initialize it then you could hardly configure the MBR through any other program.

I'm sorry, I'm not using my raid controller to install the Win 7 64 bit OS.   I removed the drive I'm trying to initialize from the raid sata port on the secondary channel and installed it in port 0 of the primary channel.  The raid is installed on the secondary channel.  Two years ago I installed two new drives in port 1 and port 0 of the sata secondary channel.  And my Raid 0 has been functioning without error for two years.  Since I now have two spare drives, that were previously part of my raid system,  I would like to reinitialize them to NTFS Win 7 drives.   I must have confused the issue when I referred to the spare unused drive as my raid drive.

When trying to reconfigured this spare drive, I have disconnected all other drives.

I hope my explanation has helped clear up the confusion I created.

Ok, this is something new. Have you tested these spare drives as standalone using the test tools made by these drives' vendor? Are they from Seagate or WD?
