What OS are you using?are you using MBR or GPT?
Thanks for your question, but this is not a matter of Operating System. before any Operating System you have to prepare the BIOS and RAID if necessary...Then install one OS (Win, Linux or Solaris). This is the question: How Intel is managing bigger HDD on the market today with a buggy BIOS?
although there may be a limitation with the matrix storage (not sure), but i do believe it possible to have a raid with more than 2tb using GPT.
yes it is possible to have RAID with more than 2 TB but not bootable..
I think I didn't make myself clear...sorry. Before installing one OS, you have to prepare the place to install that OS. I mean you chose MB, processor, memory, HDD...video and other stuff. In may case I did choose Intel board DX58SO with the RAID capabilities and "UEFI enable" option in BIOS setup.
So power on, CTRL+I to enter RAID setup. Choose disks, create volume .... and at the end under "Bootable" label is written a big "No". Why?
After several tests it's proved that is a limitation between volume size and the ability to boot from that volume. This shouldn't be for the EFI (UEFI) enabled computers, or I'm wrong? On EFI computers you must be able to boot from GPT partitions bigger than 2TB.
