    Storage spaces query...


    Hi all,

    Been trying to find an answer on this to no avail..

    I am thinking of switching over to Win 8 to take advantage of the storage spaces feature it offers.

    My question is tho, is the main OS drive able to be included in the pool ? Or is it only the extra drives you have attached ? Kinda seems stupid if you have a 1TB+ drive as the main OS just sitting there not able to be used in the pool...

    Thx guys..

    No, the main OS partition cannot be a part of the pool. It's not stupid at all, because I ask you this. How could it be part of the pool when the OS has to already be installed in order to set it up?

    You can partition your drive to create a second partition, and that partition can be a part of the pool.

    Thx for the reply Mystere,

    I am alsmost certain that you cannot add a partition to the pool.. AFAIK, you must add the entire drive or not at all.

    Well, it's a good thing you are "almost" certain. It's not true.

    You have to leave the free space unpartitioned for Storage Space to recognize it.

    Storage Spaces requires a separate drive as it's meant to be used for data redundancy/backup. Instead of using your OS drive that could die and ultimately lose everything on it, Windows forces you to use a separate drive so theoretically, you could at least still have a copy of a your data on a working drive.

    I'll find you a thread I made where I asked about Storage Spaces and it got answered REAL GOOD...if you need it.

    No, Coke.. It doesn't. It can and does work on your primary drive, you just have to have unpartitioned free space on it.

    Oh wait, I must be thinking of File History..THAT does require a separate disk.

    I was looking at the comments, and even I did not know for sure, I did some research. It seems strange that the Spaces utility notes "physical drives" in the pool, so I tested.

    I used two drives for the pool and place a small partition on one of them and added a file. I then created the pool using those two drives. A warning was given about any files being in the recycled bin if a drive was already formatted.

    Of course, after the space was created, the original partition or file was not accessible. When I deleted the pool later, the original drive had one partition the used all the space....the file was nowhere.

    So I will have to conclude it is referring to the entire drive, and not just unallocated space on the drive, since it seems to reconfigure the drive.

    My OS drive was not offered as a possibility for the pool, but there is no unallocated space on it. My Windows 7 drive, which also has no unallocated space, was offered.

    Trust me, I've done this. It does offer you unallocated space on the OS drive.
