    Can't add drive to Storage Space


    I'm creating a new Storage Space with two internal drives, a Toshiba 2TB and a Toshiba 3TB. The 2TB drive was successfully added to the storage space. However, adding the 3TB drive results in the following error:

    "Can't add drives. Check the drive connectionis and then try again. Incorrect function. (0x00000001)"

    Does Storage Space have a known issue with 3TB drives? I ask because I've run into this problem with Windows Server Backup in Windows Server 2008. I thought Microsoft would have rectified this issue with their latest OS release...

    Any help / advice will be appreciated.

    I've seen similar reports, but the issues were caused by the disk controller. The drives had the same Unique ID, and that's what had Storage Spaces confused.

    Check it in PowerShell and post results:
    Code:
    Get-PhysicalDisk | ft FriendlyName, UniqueId -auto

    Following is the output from the powershell command:

    FriendlyName Unique ID
    ___________ _________
    PhysicalDisk0 50014EE25D814916
    PhysicalDisk2 5000C50045516214
    PhysicalDisk3 5000039FF4C40B1C
    TOSHIBA DT01ACA200 5000039FF3C914B6

    The Toshiba drive is the only drive in my current storage space. PhysicalDisk3 is the 2nd drive I'm trying to add to it and, as you can see, both drives have different unique ID's. What else could be causing this issue? Should I replace the drive with another 2TB drive?

    Make sure both drives were partitioned using the GPT partitioning scheme - it's required for the 3TB drive to have a partition larger than 2TB (and Windows would have defaulted to doing so when presenting the option to partition/format it when first attached), but it's *not* required for the 2TB drive and Windows may have defaulted to MBR partitioning for it. It's technically possible to mix and match such drives in storage spaces, but I find in my experience that doing so can cause issues (especially in a mirror configuration). Just a suggestion to make sure both drives are GPT partitioned before continuing to avoid any issues there.

    Thanks for the suggestion, cluberti. However, the drive in question (3TB) is partitioned using the GPT partitioning scheme.

    The 2TB drive is also a GPT disk.

    As a side note, even if you manage to add 3TB, you'll have just 4TB of space. The way it works is: (the size of the smallest drive) multiplied by (the number of drives). Here's a good blog post highlighting SS shortcomings.

    So it's a good idea to consider advantages of losing 1TB

    Thanks for the info, Vadikan. I replaced the 3TB drive with a 2TB drive and was able to successfully create a new storage space that includes both drives.

    I have the same issue. I have the OS on a small 160GB HD on the motherboard controller and a 2TB drive on a StarTech 2 Port PCI Express Internal SATA II Controller Card. The drive works fine when it's not in a pool, but as soon as I add it to a pool I get the error reportable above and the drive becomes unformatted.

    I must add that natively, the motherboard only supports 500GB drives (thats why I bought the controller card)


    Help is needed please.
