    Quick question about SSD's Disk Management, and Pretend Raid


    I was running out of space on my 500Gb SSD, I purchased another and went about trying to create a stripe using my motherboard, it wasnt happening too well, so I joined the two SSD's using Disk Management, now I have 1TB using the two drives.
    Now, on to my question. Does anyone know if the info is stored on the drives for the "stripe" so if I have to reinstall Windows will the "stripe" show back up or will I have to rebuild it and loose everything on the drives???

    Sounds like a RAID 0 configuration which simply adds the storage of one drive to another. The "stripe" is redundant data coped from one member of a RAID array to one or more other members. In your current setup, there is no stripe, period. With RAID 0 you MUST backup the array before you can break it into individual, distinct and discrete drives. If you attempt otherwise, you will lose everything stored in that array.

    It looks like you're talking about a "spanned volume" in Windows parlance - I don't believe Windows can do actual striping. With RAID-0 striping disk blocks are evenly spread across drives at the hardware or driver level; with spanning you're literally just sticking the space of the 2nd disk to the end of the 1st disk.

    Spanned disks are a type of Dynamic Disk - metadata for these are stored in a hidden partition on the drive. If you reinstall Windows the Dynamic Disk information will be maintained as long as you don't clear out the hidden partition.

    For instance: I created a spanned volume ("New Volume") across 2 drives and then booted into Windows setup. It detected the spanned volume and after I reinstalled Windows to partition 4, all the stuff in the spanned volume was still there.

    Just saw this item on SuperUser, which (briefly) describes a successful data recovery strategy from a broken pair of spanned volumes. could be just the ticket to helping you fix your problem: Mirrored Drives both failed after windows reinstall - Super User.
