    I had 2 drives in a RAID 1 config (uses Intel Matrix Storage) that are 250gb, and replaced with 2 drives that are 1TB which have been running for a month as smaller

    drives because the array doesn't repartition. Vista Business 32bit.

    Installed the new version of Intel Matrix Storage and ran it, which allowed me to extend the drive to use the unused area of the drive. Rebooted fine. Used it for

    a while yesterday with no problems.

    Installed Acronis DD 10 (just purchased) and was able to see the partitions. I wanted a larger contiguous "C" drive, rather than adding a new separate partition,

    so I went through the process on DD to do the following:

    My drive originally had 3 partitions (Dell did this... 10gb recovery, 167gb main c drive, 55gb backup)
    I instructed it to:
    shorten the backup from 55gb to 10gb because I don't use it.
    move that partition to the end
    combine the original C drive partition with the new unused space, plus recovered space from the "backup" area.

    I committed the changes and it asked to reboot, which I did.

    Boot process started and DD intercepted before windows booted and I watched as it gave me status on a black screen with white letters.

    It performed steps 1/2/3 without any problems.

    On step 4, it failed with this message:

    Operation Error: Reqblocks Miscalculated

    Now the drive won't boot. It asks for my windows CD and I should repair windows. I have not done this step.

    I still have the old drives that I can put in and run (although they are out of date), so at least I can boot, but what exact steps do I need to do to restore my

    new drives and data? Are there any other utilities I need to be able to recover my drives intact?

    I have an external USB enclosure that I can use to attach one of the drives if that will help... I presume I can attempt to format that way if needed.


    Thank you!

    I chatted with Adnan and he instructed me to do the following:

    Adnan: 1. Put the Windows Vista installation disc in the CD\DVD disc
    drive, and then (re)start the computer

    Adnan: 2. Press a key when you are prompted

    Adnan: 3. Select language, time, currency, keyboard or input method, and
    then click “Next”.

    Adnan: 4. Click Repair your computer

    Adnan: 5. Click the operating system that you want to repair, and then
    click “Next”.

    Adnan: 6. In the System Recovery Options dialog box click Command Prompt.

    Adnan: 7. Type the following:

    Adnan: Bootrec.exe /FixMbr

    Adnan: Bootrec.exe /FixBoot

    Adnan: Bootrec.exe /RebuildBcd

    Adnan: This command scans all disks for installations that are compatible
    with Windows Vista. Additionally, this option lets you select the
    installations that you want to add to the Boot Configuration Data store.

    I started to follow his advice and did these steps:
    put in win cd
    pressed enter to continue
    selected defaults of lang/time/curr/kb and pressed next
    clicked repair
    it says: win found prob w startup options, repair & restart? details shows:
    startup will be deleted: ms win vista partition not found
    startup will be added: win vista bus recovered (C: 886701mb)
    part e: 10240mb
    copy of current boot config will be put here:

    clicked repair and restart. it restarted
    did not click any key to start from cd (win CD still in drive)
    acronis started up in blk/white 100% flashed quickly
    it restarted again quickly without asking
    again not clikcing to boot from cd
    now showing "win error recovery", launch startup repair recom OR start win

    Note: it did NOT show me the " System Recovery Options dialog box " so I
    was not able to enter those commands.

    So the question is: What do I do now? Launch startup repair (recommended)
    OR Start windows normally OR redo the repair process?

    Thank you.

    Welcome to the forum.

    Assuming the partitions are actually not corrupted, DD probably didn't "unhook" itself from the Windows booting process because it failed.

    When you boot to the DD CD and look at the drive, do your partitions look correct?

    Normally, it's best to do the type of changes you did when booted to the DD CD instead of from Windows. It's also best to do them one at a time instead of telling DD to do them all automatically. This allows you to have control over the process and also know if one step fails or doesn't complete properly before the next one starts.

    If you boot to the Vista DVD and enter the Repair mode and start the Command Prompt, does chkdsk report that there are errors on the Vista partition? At this point, I wouldn't use either the /f or /r options to fix any errors, just check to see if there are any.

    Do you have a backup of the drive (an image backup, for example)?
