How to extend the iMac Pro to X99 [Successful Build/Extended Guide]

[geteng666]

Hi KGP,

Followed your guide, thanks!
One major issue: my SATA hard drive is not recognizable.
If I put the hdd into a usb adapter, they can be correctly mounted. But as long as using SATA, they are "uninitialized".

Do you know why?

Update:
During the boot output, there's some traces:

How did you format your HDD?

How did you format your HDD?

I didn't format the HDDs. They are storage drives.
The system is on NVMe drive, which was formatted to APFS.

But if they are storage drives the should have some formatting, isn't it? Otherwise how do you store your data on them?
Did you use the HDDs before under Windows or Linux? Or do the HDDs still have factory formatting?

I guess your HDDs are not recognised due to a formatting not accepted by OS X! Do you see the HDDs at least in Apple's Disk Utility?

I have been using those HDDs in mac. It was 10.12.6 before today.
The format scheme is HFS+.

The system can recognize them when the HDD inside USB enclosure.
They are not recognizable as internal drive connected by SATA.

I've never seen this issue before. I'm guessing related to ahci?

Are they compound within a RAID? Did you try to mount the RAID manually in Apple's disk utility?

They are just standalone disks. No RAID..

 

[kgp]

They are just standalone disks. No RAID..

Anyway, did you try to manually mount one of them in Apple's Disk Utility or via terminal command?

Not mountable via Disk Utility app.

Under /dev, there're only disk2 and dis3, no partition file(disk2s0, etc).
I tried:

diskutil repairDisk /dev/disk2

Nonexistent, unknown, or damaged partition map scheme
If you are sure this disk contains a (damaged) APM, MBR, or GPT partition map,
you can hereby try to repair it enough to be recognized as a map; another
"diskutil repairDisk /dev/disk2" might then be necessary for further repairs
Proceed? (y/N) y
Error repairing map: Input/output error (5)

But it must not be corrupted data, as they are good when connecting by USB

Can you format one of them? Or do they all contain important data?
