    Intel Rapid Storage Technology detects Raid5 but Win7 can't see partitions.

    ichbinder

      Hello people!

       

      I have an Intel ICH9R controller on an Asus Maximus Extreme (first edition, see http://www.asus.com/Motherboards/Intel_Socket_775/Maximus_Extreme/ ). As disk configuration I have four 1TB Samsung HD103UJ, three of them combined to a Raid5 array. In Windows 7 SP1, I installed the Intel Rapid Storage Technology, 9.6.0.1014, abbrv. IRST. It detects the Raid5 array as one big array, just fine. It does not tell any information about the filesystems that exist on that Raid5.

      It has already been used in Linux before, where I created one EXT3 and one NTFS parition on the array. I'm not even sure if the partitions should even be detected by IRST or not. The main problem is, that I can't access the NTFS partition on the Raid5 in my Win7.

      Am I doing something wrong in the IRST control center or do I need further drivers or what is the problem? :-/

      If you need anymore information, let me know.

       

      First post, so please be gracious and give me a warm welcome. And excuse my English, non-native speaker.

       

      Thanks for taking a look at my issue and have a nice day,

          It sounds like the new volume hasn't been partitioned yet (as a RAID volume)? What is Disk Management showing the status of the drive as... Control Panel (using classic menu) -> Administrative Tools -> Computer Management -> Storage -> Disk Management? That's the area in Windows 7 where you can configure away with partitions and formatting etc to suit your needs.

           

          I assume you backed up your data on the volume from within linux when that was installed so as long as there's nothing on there you need to keep just partition and/or format away!

            Hey Flying_Kiwi, thanks for your reply!

             

            It has been  partitioned, using gparted in linux, or something similar, years ago.  One partition is ext3, the other one is ntfs. I can mount and access  both perfectly in linux.

            So, here a screenshot of my disk management in Win7:

            It detects the two partitions, just not that one of them is a NTFS... :-/ But why? And what can I do? In linux, it says ntfs-3g and like I said, I partitioned it in linux to NTFS... I've done that before with non-Raid disks, partitioned them in linux and windows detected them just fine... so, where's the problem here?

            And repartition it using windows is no option as I couldn't backup the data since I didn't have a spare 2GB anywhere...

             

            Thanks again,

            ichbinder

              I'm aware that Win 7 uses a new type of NTFS and that's why it's not possible to perform a direct upgrade installation over some earlier NTFS using OSs. I'm unsure of the specifics but I strongly suspect that's why your partitions contents aren't showing up in Win 7.

               

              Time to buy a 2 TB External drive for backups then I think (that's what I use - I assume you meant TB rather than GB otherwise you could just burn a DVD to back it all up). I use RAID 0+1 over 4 identical HDDs but still have my backup drive (which I can connect through my eSATA port).

                and after i remove "IRST" the problem is fix, i tried with kingston ssd at first(sorry don't take screenshot that time) and found out that my ssd somewhat is missing. and then i change to my old hdd and found out the same case.
