The disks size aren't being misreported. And it's also a UEFI [1] computer, not BIOS [2], therefore again there shouldn't be any concern about firmware induced disk size misinterpretation. But then, I'd also not expect a UEFI computer to offer a GPT incompatible RAID implementation either – I'm still hoping I've got this wrong somehow. Chris Murphy [1] UEFI has no bugs. Not a single one. [2] I can't be the only one who finds it irritating that even the manufacturers persist in conflating UEFI and BIOS: All of Intel's firmware downloads for Günther's/OP's motherboard are referred to as BIOS. I really wish they wouldn't do that.-- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
