Kext For Intel SATA Controller in RAID Mode

[TonyTech]

There is no support for actual Intel RAID...
If you want RAID, use macOS software RAID.

If you have at least one "normal" partition (eg. a small FAT32, NTFS, or HFS+J partition) on a disk, the annoying message will go away.

How would I add a normal partition to the other disk? Windows sees the two disks as one disk...

You would need to add it outside of Windows and outside the RAID0 setup.

Hi. First sorry for my poor english. I have 2xSSD set RAID mode in BIOS. I dual boot with Windows 10.
1. So can I install macOS 10.12 on it ?
2. If can't. I will set to AHCI in BIOS and install macOS in software RAID.
But have a problem, Windows can't install in software RAID, it will identify as AHCI. But I want to install both 2 operating system in RAID.
Do you have any solutions?
Thank you.

1. You cannot install macOS to the RAID volume. You must install to something that is AHCI (or looks like AHCI..eg. single non-striped device).
2. Yes.
Windows can be installed via AHCI.
Or you could install Windows to a BIOS RAID0 stripe, but still install macOS to another set of devices not in the same RAID grouping (via AHCI, software RAID if you want).
Point is, macOS under no conditions will see the RAID grouping... it will only see individual devices...

I did not understand "another set of devices not in the same RAID grouping". Is it a third drive or one of two drive which set in BIOS RAID ?
(My laptop has only 2 drive)

I thought you had three drives for some reason.
With only 2 drives, not possible.
You need 2 drives for a RAID set on Windows.
And you need at least one not in that set for macOS.
With only two, you can't use RAID.

I understood everything.
Thank you very much

Is there any hope that one day there will be support for Intel RAID? I have 2 x 8TB in RAID 1 encrypted with VeraCrypt, and this is only thing keeping me going between Windows and Hackintosh.

Hi Rehabman,

In a similar situation here - hoping you can help!

I have a RAID set up on my integrated Intel SATA controller ( Hardware ID: PCI\VEN_8086&DEV_2822&SUBSYS_B0051458&REV_31 ) and since my macOS boot drive is on that controller - but not part of the array - naturally, will not boot.

I am considering an additional pci-e controller hoping to be able to boot macOS off of that one, or else to put the PCI-e one in RAID mode so I can boot macOS off the Intel one in AHCI.

Naturally, the following questions occur:

1. If I get a SATA3 PCI-e controller and put it in AHCI mode and (hopefully) boot macOS off of that - would it be able to read/write to an exFAT-formatted RAID on the Intel controller?
2. Else, is it possible to boot macOS off of my current Intel controller in RAID mode? Furthermore - would it be able to read/write to that ex-FAT-formatted RAID on the same Intel controller if it can boot?

Thanks!

That controller setup can work with SATA-RAID-unsupported.kext.

Any volumes/partitions in RAID will not be recognized by macOS.
