  2. Problem with External Disk management.

    Hi,

    Was the Simple Volume greyed out?

    The reason behind that is because Windows operating system supports both
    MBR
    (Master Boot Record) and GPT (GUID Partition Table) disk, and the two disk types have their own characteristics on their performance.

    MBR (Master Boot Record)

    • Can only support up to 2T capacity.
    • Can only create up to 4 primary partitions.
    • Once you want to create more partitions for different files, you have to convert one primary partition to extended partition.

    GPT (GUID Partition Table) breaks out the limitations of MBR

    • Supports more than 2 TB capacity
    • You can create 128 partitions on GPT disk

    It seems that your hard drive is MBR that can only use up to 2 TB. That’s why the
    New Simple Volume greyed out beyond 2 TB in Windows Disk Management. To resolve it, you should change the MBR into GPT disk so that the part beyond 2 TB can be available.

    Here's how to do it from the Disk Management:

    • Right-click This PC -> Manage -> Disk Management
    • Right-click your hard drive and select “Convert to GPT Disk
    • Then, follow the guidance to finish this conversion.
    NOTE: When you use Disk Management to convert disk from MBR to GPT and there are some files on the 3TB hard drive, you have to delete all the data on the disk. Because Disk Management can only
    convert an empty MBR into GPT. Otherwise, the Convert to GPT Disk would be grayed out.

    Let us know how that turned out for you.
