[SOLVED] High Sierra doesn't recognize additional HD's on GIGABYTE Z97X-UD3H

[Troy.Blackburn]

I did a clean install of High Sierra exactly as per the guide posted on this site:

https://www.tonymacx86.com/threads/...any-supported-intel-based-pc.235474/#download

So far everything seems to work fine, except that I can't mount drives other than the boot drive. High Sierra recognizes that the drives exist; however, sees them as not being initialized. If I attempt to initialize a drive, it states that it can't write to the last block.

Any help would be greatly appreciated!

Thank You

If you are having trouble I would just do it using terminal.
You can just google instructions "format disk using terminal" or some variation and find instructions on how to do so

I appreciate the suggestion; however, I think it's going to require something more than that. It's recognizing the existence of, but not allowing me to mount exFAT & NTFS drives that are already formatted and have data on them. These drives were previously accessible when running macOS Sierra. There have been no hardware changes.

In your initial post #1 you stated

• That suggests there are bad sectors in those disks.
• See if you can connect the disks to Windows and recover your data ASAP.

I don't think it's that. I think it's something in either my selection of kexts or Clover settings. If I move the drive to a system with exactly the same hardware, but running macOS Sierra, it recognizes the drives, mounts them and I have access to the data without any problems. The drives are HGST 3 & 4 TB drives and I've tested several of them.

By no means am I dismissing any suggestions, I'm checking even that which I would otherwise assume to be obvious.

Thank You

I've done some more testing and it's definitely something relating to my new Clover/High Sierra install. I've moved the inaccessible drives to a different system running macOS Sierra and also moved a boot drive running macOS Sierra to this system and am able to access the drives without any issues.

I'm thinking it's got to either be a kext issue or a Clover config issue, any suggestions?

I had MB BIOS settings with SATA HD Hot Swap Enabled, which worked fine with previous Clover/macOS Sierra install, but doesn't seem to work with new Clover/macOS High Sierra install. I'll have to do more testing, but initially looks like the issue is with Clover. Under previous install I would see other drives in Clover Boot Menu with Hot Swap enabled, under new install I only see other drives with Hot Swap Disabled.
