RAID0 Help!

System was built 7 months ago and has never worked right. With intensions of purchasing Vista with Windows 7 upgrade, I was never able to perform a Windows update or Windows disk defragmenter. Update would have an error and defragmenter would hang for 8+ hours.

I have been having blue screen errors related to the memory after extended use. When my PC was working last, I had my cell phone connected to the USB drive to charge and not thinking, I rerstarted the PC. Usually I have to unplug the USB and restart, which I did.

During post, all hard drives and storage devices are present.

When the Intel Matrix Storage Manager appears, RAID Volume has a Status of Normal and Bootable is Yes. Under Physical Disks, Port 1 displays the Type/Status(Vol ID) as "Error Occurred (0)" and Port 3 appears as "Member Disk (0)".

What has been tried:
Boot Normally to Windows: System hangs for 1+ hours.
F8 to Safe Mode (all options tried): System hangs for 1+ hours.
Last known working configuration: System hangs for 1+ hours.
Inserted Windows Vista 64 disk to attempt recovery console: "Windows failed to start. A recent hardware or software change might be the cause." has a Status: 0x0000225 and Info states: "An unexpected Error Occurred."

Unfortunately, I just moved the data from another PC a few months ago and do not have a full backup of the data. For this reason I have not tried to delete the RAID volume and create another simply because I don't know if this will delete the data.

I purchased 2 more WD1001FALS today as well as 2 copies of Windows 7 Ultimate 64. If I setup 7 on the 2 new drives in a RAID0 configuration, can I go back later and connect my original 2 drives to add to the array without loosing my data?

One other option I thought of was to install 7 on the 2 new drives and connect my original 2 as regular hard drives and then run chkdsk on them.

I'm really stressing out here! Any help is much appreciated.

  1. Fix the PC?

    First get a stable system:
    - memtest without problems
    - check SMART output on HDDs

    If you need to recover the contents on the RAID, try this:
    http://www.tomshardware.co.uk/forum/252965-14-transfer-raid-array#t1781278
  2. Your story has conflicting facts. You say the Intel Matrix Storage Manager says you have a RAID volume that is Normal and Bootable. Yet it also tells you that, of the two disks you have, one is good and one has an error condition. Your title says this is a RAID0 array, and your machine apparently cannot even get started on loading Windows from the HDD system. So is all is consistent in indicating a corrupted member disk in a RAID0 array, EXCEPT that you are being told that array is OK and bootable!!

    You CAN install two new drives in a new RAID0 array and install Win 7 to them. This will NOT do anything to solve the problem on your old array, however. It only will give you a machine that can run fine on the new array.

    Once you have errors on one disk of a RAID0 array, your hopes of recovering ANYTHING from that system are about zero. Does not matter whether you have hardware trouble or just corrupted data in a VERY limited section of the one disk. Since all of that system's files are interleaved between the two drives you need BOTH to be error-free to get anything from them. In some cases you might have trouble only with one or two files corrupted, but that obviously is not your case.

    Having a fully functioning new RAID0 array working still won't make recovery of your old array any easier. If you break up the old array back down to individual independent drives, neither will have any meaningful data you can recover. Running Chkdsk or any other utility on them will only make it even more impossible, (if that's possible). IF you want to simply say goodbye to all your old data and try to fix the two old drives so they can be re-used again, the simple process might be to break the array and treat each old drive like any other - repair what you can, use if possible - and forget their former roles as array members.

    You CAN look around for utilities that will try to recover as much or your old data as possible from a degraded RAID0 array. That might even be easier once you have the new array installed and working under Win 7. In that scenario at least you'd have a place to copy any recovered data to. If you want to try that, stop trying to do anything further with your old array. Install the new drives and Win 7. Make SURE you don't do anything with the old array as you do this. Don't try to use the old array at all until you have done what you can to try data recovery from them.

    You may want to post your SMART info here. You get the SMART information from your HDD by using a small application that can read SMART info. If using Ubuntu, simply open a terminal (Applications->Accessories->Terminal) and type:

    # this installs smartmontools - a program that reads SMART info
    sudo apt-get install smartmontools
    # now use smartctl to retrieve info from your HDD:
    sudo smartctl -a /dev/sda

    You may have to turn on SMART first, "man smartctl" gives you more options. If you execute the smartctl command as above and it displays a long list of data, then you're good. Copy&Paste the data over here for us to look at.

    Also, try reading from your disk:
    sudo dd if=/dev/sda of=/dev/null bs=1M
    (warning: do not make mistakes with this command or it may lead to data-loss!)
    (currently, this command reads from disk /dev/sda from begin to end, and does nothing with the data (gets written to /dev/null which means this command only reads and does not write anything)
  4. I added a few photos of the known issue. The only other thing I noticed was when I reset my BIOS and reconfigured, No drives show in BIOS with RAID enabled.

    Thanks again for the help.

    BTW, my system specs are listed in my public profile under system specs.
  5. Just a broken RAID0 setup - your data is still recoverable!
  6. Wow Sub mesa I love this utility!

    The following was copied from the terminal. I think I need a bit of help with turning the SMART on though.

  7. Hey there! You're almost done, you made a slight typo with the second last command:

    sudo smartctl -a/dev/sda
    should be:
    sudo smartctl -a /dev/sda
    (the space after -a)

    Also, your last command indicates a bad sector at 327MiB/343MB location. The smart log should have more info on this. Please retry the command as above and post the information here, and we can have a look. :)
  8. If I use the command as you state above, I get "Command not found" returned.

    On another headache side note, when I look at Palimpsest Disk Utility under Administration, 1st disk shows as 2000GB RAID Component and second shows as 18446743074 GB Free Unallocated Space.

    Please tell me my data may still be there...
  9. Did you try the command after rebooting the livecd? Remember, while using the livecd anything you install is gone after you reboot. So you would need to:

    sudo apt-get install smartmontools
    sudo smartctl -a /dev/sda

    you can try /dev/sdb for second hdd etc. To get a list of your drives:
    dmesg | grep sd

    Also look in GParted (Partition Editor) under System->Administration to help you determine what drives get which names.
  10. OK, I understand that ubuntu is loaded each time I reboot and that the settings are not saved.

    To run a command as administrator (user "root"), use "sudo <command>".
    See "man sudo_root" for details.

    Gparted shows /dev/sda (931.51 GiB) and /dev/sdb (931.51 GiB) both show Unallocated under partition and File System.

    Please let me know what the next step is Sub Mesa.

    Thanks
  11. The SMART info on the /dev/sdb device looks good, no apparent errors here. However, i did not get the full output of the smartctl -a /dev/sda command; it appears data is missing after:

    General SMART Values:
    Offline data collection status: (0x84) Offline data collection activity
    ..
    (more data should be here)
    ..
    ubuntu@ubuntu:~$ sudo smartctl -a /dev/sdb

    Could you maybe try again? It might be worthwhile to check for disk damage prior to trying to recover. Probably the /dev/sda disk has some bad sectors as the surface check you performed (the sudo dd command) indicates a failure at some point.
  12. Perhaps this forum doesn't allow you to post messages this big. In that case, please only paste the output for the "sudo smartctl -a /dev/sda" command.
  13. Yeah, that's the case, must have been too big. Returned:

    ubuntu@ubuntu:~$ sudo smartctl -a /dev/sda
