I have two identical drives which are 2TB's each. What I would like to do is setup RAID 0, now the issue is I have converted both disks to dynamic disks, when I right click on the "unallocated" drive "New Striped Volume" is grayed out. UAC is turned off btw.
Can it be the size of the disks that is the issue?
Thank you for time, any comments or suggestions are much appreciated.
You're running into a couple of limitations here. First, MBR partitions (the kind that a BIOS can boot from and Windows can be installed to) must be under 2TB in size.
Since creating this RAID 0 array would require the volume to be set up as a GPT partition (GPT = GUID Partition Table), you would have to delete the volume and re-format the drive, which obviously you cannot do while you have an active copy of Windows running from that volume. Doing this offline would work, but you would not be able to boot from the GPT volume once you created it. Only EFI - or UEFI - based systems can do this (which is the second limitation).
