    RAID1 problems

    Nicoven72

      Hello,

      I have a RAID1 system.

      Windows 7 says me that there is a problem with the disk (this means with one of the two disks that make the array).

      If one of the two hdd was damaged (but not eliminated from the array), can this affect the performance of the entire RAID system (for example during windows updates)?

      The option "Reset disks to non-RAID" during RAID BIOS, could be the solution to find the faulty disk? (I do this excluding from array disk1 and then disk2 randomly)

      Choosing "Create RAID volume" after have been chosen "Reset disks to non-RAID" (leaving BIOS hd configuration as RAID), will it do a full entire new copy from disk1 to disk2 or only an incremental copy?

      Anyway, if you have understood my problem, can you suggest me a solution?

      Thank you.

          Hello :
           
          In regard to the first question, no, it will not affect the performance on the PC because the RAID 1 gets the information from one hard drive.
           
          Also, in order to replace the defective hard drive, the option to "Reset disks to non-RAID" will be needed, so you can disconnect the defective hard drive and connect the new one and rebuild the RAID without losing the information on it.
           
          Once you do that if you choose "Create RAID volume", it will create the RAID 1 from scratch and all the information will be lost, so depending on the chipset the PC has, there will be different options to rebuild the RAID 1 from an existing hard drive.
           
          Based on that, what is the model of the chipset?
           
          What is the model of the motherboard?
           
          If this is a laptop, what is the model of the laptop?
           
          Any further questions or if you need more information, please let me know.
           
          Regards

            Here is the chipset of the RAId controller (is not a laptop)

            Is that enough?

            Thank you.

                Hello :
                 
                Thank you very much for providing that information.
                 
                The following will be the IRST version that you need to install:
                 
                https://downloadcenter.intel.com/download/22676/Intel-Rapid-Storage-Technology-Intel-RST-RAID-Driver?product=55005
                 
                And then from the following guide please check step 5 on page 31, that is the option you need to rebuild the RAID without losing the information and getting it from the disk that is still working properly.

                  Thank you very much.

                  I have done what you said and now I can get useful informations about the RAID status.

                  I post you this screenshot: seems that one disk has some problems.

                  Hope you understand italian: it talks about event SMART risk...

                    The disk that seems to have problems is that the new one, or is the one that you have been using all this time?

                      It is the one that I have been using all this time.

                        In order to make sure about the status of that hard drive, please access the control + I menu, to do that just restart the PC and as soon as it is starting up, press and hold “control” and tab” I” several times until you get to that menu, and then please if it is possible to provide a screen shot or a picture of it so we can verify the information showing there.

                            What that error means is that the hard drive is about to failed, so the chip inside of it sends the alert to the SATA controller and that is why you get the SMART event error, you can use the option: “sopprimere evento SMART” that will set the RAID back to how it was, but by using this option you will be ignoring the message, but the problem is still there and the hard drive will failed at any moment, best thing to do, replace the hard drive as soon as possible.
                             
                            Any questions, please let me know.

                              This is exactly what I thought.

                              Thank you very much Alberto.

                                  Alberto,

                                  I would like to know if it suitable cloning the NOT failed disk before rebuild the RAID1 system.

                                  Is it possible that something goes wrong and I lose all the data in the NOT failed disk during the operation?

                                  The NOT failed disk is in a particular format related to RAID1 or is an absolutely normal disk (as if it was alone and NOT in a RAID system)?

                                  Thank you.

                                    In regard to your question, yes, it is suitable to clone the not failed disk, however one of the best things to do if you have the option, will be to get another disk with the same size as the one that is currently working, connect it to the PC and rebuild the RAID 1.
                                     
                                    About your second question, nothing should happen or go wrong if you try to clone the disk, the information will not get lost.
                                     
                                    At this point, the disk is within the RAID structure, that is why the option to rebuild the RAID is better, but even though it is still under RAID 1 structure you can still clone it, the only way to lost the information will be if you delete the partition on the disk or if the disk gets defective.
                                     
                                    Any questions, please let me know.
