stefano.85 Posted September 16, 2017 Share Posted September 16, 2017 Goodmorning, I have just did a clean USB installation of Mac OS 10.13 GM on my SSD in APFS, it seems that is working quite fine apart the fact that I can't see my 2 internal HDD formatted in HFS+ (I also have the backup in one of those). when Mac OS boot up it tells me that 3 drives are illegible and need to be formatted (like when you connect a wrong partitioned drive in the past). Even in Disk utility I can't see them. In system report I can see the two HDs... (I have attached a screenshot below) EDIT: clover r4207 installed on the EFI of the main SSD and did a clean configuration apart from my DSDT.aml installed in the right folder My system is the first one in the rig, tell me if you need something else for troubleshooting. Thank you for your help Link to comment Share on other sites More sharing options...
Vinicius P. Miranda Posted September 17, 2017 Share Posted September 17, 2017 I also have the same problem. I would like to know how to solve it. Also I wanted to know a way to make the disk not be mounted at startup, because 1 of the disks that is in Raid0 with Windows 10 always gives this error even using third-party software. If it does not try to mount it at startup, this error would not appear. Link to comment Share on other sites More sharing options...
fusion71au Posted September 17, 2017 Share Posted September 17, 2017 @stefano.85, I see the same error (for certain disks but not others) on my 5 series desktop since DB3: "The disk you inserted was not readable on this computer". The fix is to replace AppleAHCIPort.kext v329 with v328 from DB2/PB1_17A291m. The v328 kext in that link has a higher bundle version that will give it priority loading over v329 in /System/Library/Extensions if you install it in /Library/Extensions (so doesn't get over-written during updates). Good Luck! Link to comment Share on other sites More sharing options...

stefano.85 Posted September 20, 2017 Author Share Posted September 20, 2017 Fusion, I ask you one more thing... is it possible to install AppleAHCIPort.kext to clover kexts folder instead of S/L/E one? did you try it? I mean in case of future updates.... Link to comment Share on other sites More sharing options...
enlaid Posted September 26, 2017 Share Posted September 26, 2017 I found better solution! Disable hot plug for HDD in bios (if you can) and problem solved! Works with vanilla AppleAHCIPort v329. 2 Link to comment Share on other sites More sharing options...
