RAID-Free: Changing from RAID1 to non-RAID

  • I checked the forum on this one, but still looking for some clarification re DOs and DONTS!
     
    My 9200 machine will arrive configured with Windows VISTA in a RAID1 mirrored configuration. I am looking for the correct instructions to change both disks from that configuration to a non-RAID configuration without losing any data in the main drive (drive 0). I want to be  RAID-Free !  In doing so, I want to avoid some of the pitfalls of:
     
     a) seemingly being successful, only to find the system rebuilding the RAID configuration on reboot
     b) getting a blue screen on reboot
     c) losing the data on BOTH drives ....specifically the Ctrl I warnings in the manual that  say "If your computer currently boots to RAID and you delete the RAID volume in the
    Intel RAID Option ROM, utility, your computer will become unbootable."

    Is the following correct: ??
     
    0) (Is this neceesary ? ) Take a full image copy of Drive C before you start.
    1) Boot the system
    2) As it boots, press  press CTRL+i to go into the RAID BIOS setup
    3) You will see 4 options : 1 create RAID volume / 2 delete RAID volume / 3 Reset disks to Non-RAID / 4 Exit
    4) Select Option 3- Reset Disks to Non-Raid
    5) The above will give a warning about data loss, but that is a generic warning because resetting a RAID0 volume *would* cause data loss, but with RAID1 will be result in no data loss on either drive. ( << Really???)
    6) After breaking a RAID-1, windows should show two separate hard drives that are exactly the same and will assign a letter to the second drive.
    7) Rebbot the system to confirm the above.
    8) (Is this a must??) : Format the second hard drive.
     
    ....but when an XP user tried the above, it did not go so smooth ..." when I rebooted I got the Blue screen Stop message # 0x0000007b with instructions to check the drive for viruses and do a chkdsk. I did a chkdsk and everything seemed to be ok except the chkdsk message stated that that one or more errors had been corrected, but I still can't get past the Blue Screen Stop 7b message."
     
     
    Many thanks

    During boot up of your system, at the Intel Matix ROM Utility screen press CTRL-I (that's an eye) to enter the ROM utility. Select "Delete RAID volume". You will be warned that you will lose all your data which will not happen for a RAID 1 setup. Confirm the delete and exit the ROM utility. Your system will reboot and you will see at the ROM utility that you now have non-RAID drives. Let your system boot into Vista. In Vista you will see two identical drives with identical partitions. You can then do whatever you want to the 2nd hard drive. For example, you can reformat the entire drive, partition it the way you want, etc. I've done this many times without issues.

  • Thanks.

    So what then is the diff between  "2 delete RAID volume" and "3 Reset disks to Non-RAID " ??
  • I have only used the " Delete RAID Volume" option for a RAID 1 volume. So, I don't know what the difference is. You may want to research this via the Web or simply know that the Delete option will always delete a RAID 1 volume without losing data.

  • I went with Delete Raid Volume - but even ignoring the warnings, it gave me no options to select, and impliedI was selecting two drives....so I whimped out.
     
    Went for Option 3 - Reset to Non Raid  - it allowed be to select the mirrored drive... but it really just did a rebuild and brought me back to square one.
     
    So I went back to what you said, Delete Raid Volume, ignore the warnings, selected the only option there, and closed my eyes, and spoke the words "hope he is right' . Worked fine. Two independant drives. Both in tact. No RAID. Yay!  I am RAID FREE !!! .
     
    Thanks!!
     
     
     
  • I don't suppose you then decided to re-migrate back to RAID1 and did this successfully without losing data or having to rebuild everything?
  • Nope, I am still RAID free and after almost two years like this, its perfect.

     

    I have automated daily file backups to the second hard drive PLUS another independant set of automated daily file backups (staggered 12 hours) to an external drive PLUS a weekly full image backup to the external drive, PLUS those images are staggered on a 3 week cycle.

     

    In this way, for 99.9999% of the time, I enjoy full use of all the storage I own, and have full confidence that my data is secure and I can easily recover data that may have become corrupt or was accidentally overeritten or erased, by going back to a copy saved 12 hours ago, 24 hours aga, 1 week, or two weeks or 3 weeks ago (or DVD backups before that).

     

    For that .00001% of the time when I need to deal with a hard drive failure, sure I will be inconvienced and need to manaully recover from my image and file backups, but thats no big deal. I can essily recover, and besides, I have four other machines in the house if I need to do something in a hurry, and each can access the backup drive.

     

    RAID-free is a perfect arrangement for me.

     

    Re your post, I gather you want to go back to (or first establish) a RAID1 configuration. Is there an issue you are facing in doing this??

  • Thanks for asking ..... Rather than cut and paste the other thread in here, could you do a search for "Unable to stop RAID1" - this is my current issue.

     

    That being said, I am very tempted to follow your line and give myself access to all my available storage and manage backups, disk copy etc myself. While obviously providing a level of resilience, RAID1 may be overkill for me at the moment.

     

    But if you have any ideas on how to resolve my problem, they would be gratefully received.

     

    Thanks. 

  • Finally got around to it. Followed your instructions and, hey presto, have loads of space and no RAID - not a great loss as I have a "disk copy" on my second drive as well as backups so if my first disk fails, I'll simply boot from the second.  Thanks for the advice.
