    Help in KEEPING RAID systems after format!


    Hello,
    I have 3 RAID systems;
    1. 2x HDD's Internals, in Simple Mode.
    2. 4x HDD's Externals, in Spanned Mode.
    3. 3x HDD's Externals, in Spanned Mode.
    ( 2 & 3; In MediaSonic enclosure, eSata Cable with PCI-Express )

    I want to format my PC with clean install,
    the problem is that all these RAID's are
    SoftWare & the HDD's are DYNAMIC.

    Sorry for my lack of knowledge, but will i be able to use this RAID's normally after the format?
    Or i need to break all RAID's, then make it again with the newly installed windows? & HOW?!

    PS: my windows 8.1 Pro is on separate SSD.

    You will not be able to, after you do the format on the drives. You have to set your RAID back up afterwards. There are some motherboards, that you can specify in the bios, the Raid format. There are also some PCIe Boards, that will allow you to do the same thing.

    You may be better in finding a motherboard that allows you to decide which RAID format you want (ie 1, 5, 10, 0 or JBOD). Even better would just go with a RAID enclosure, vs having one computer do it, unless that computer is being used as a server, then see above.

    As I mentioned, two of the RAIDs are inside the Enclosure, and this is my motherboard:-

    I have simple and spanned raids, how to know 1, 5, 10, 0 or JBOD types?

    Yes you can break the system if you change the RAID setup. As for data loss, it depends on what you used for your RAID profile. As for knowing which RAID type you are using, Windows would tell you, the bios would tell you, software like HDInfo would also tell you. Even a Linux Live CD like Xubuntu 12.04 LTS, would tell you, if you used something like GPartd.

    Great to know that,

    I don't know a lot about raid, but as you say you have software raid ,but they are not really a raid setup, from what I just read ,so in my opinion ,it looks like you would have to recreate software ones after the fresh install ,and It say to back up data on the drives before creating a new spanned mode raid

    from what i gather;
    I should copy all the data from the internal raid, and then break it.
    As for the External ( Enclosure HDD's ), it's hard to copy; it's more than
    20 TeraBytes of data, so i am not even remotely able to copy it anywhere!

    Is it possible to break these Raids without potential data loss?

    as I said I don't know a lot about raid ,but just reading around a bit it seems if the raid is broken data might be lost ,haven't found a site yet that gives full details ,still looking.

    edit :just found this ,so im making an assumption that by reinstalling windows will break the spanned disk, but not 100% sure ,and not sure if that will cause data loss.
    --------------------

    Unlike RAID, spanned volumes have no fault-tolerance, so if any disk fails, the data on the whole volume could be lost.

    It's good that none of my disks are failing, I want to break the spanning officially if it's possible!

    Also a correction; if one disk fails; only the data on this disk is lost,
    but i have to break the span if i want to use the data which on another disks!
