Hello

I have dual boot (MacOS X 10.5.8 and MorphOS 3.13) PowerMac. When i boot to MacOS X don't recognise MorphOS file system and annoying requester of initialization of disk with MoorphOS partitions popup (and after this USB device failure information and to check if it's plugged to auxiliary power supply). I must manually give "ignore" option (and close USB power information) every time when MacOS X boot.

Is there possibility to add always ignoring this disk?

I remember such issue, where solutions were given:

https://morph.zone/modules/newbb_plus/viewtopic.php?topic_id=9129&forum=3

Is this the issue you are experiencing?

No, i have two different disks. First is with Boot partition (for MorphOS) and MacOS X partitions. Second is from my old Pegasos II and only have MorphOS partitions. I have not any error with Boot partition. MacOS X doesn't recognise second disk (with MorphOS partitions only) and every time when i boot MacOS X i have requester with "eject" "initialize" and "ignore" options.

On Mac this behaviour normaly accours, if 2nd HD has a RDB instead of a Mac-rootblock. RDB-HDs cannot be recognized by OSX....

I know that it's not recognized. I'm asking how to "teach" MacOS to ignore this disk.

You could probably modify OSX’s startup/login scripts to eject it. Or format the drive.

Hello

So there is no option in system settings in MacOS X to do this more comfortable way?
I'm rather for first option.
How to do such script, because about MacOS X i'm completely green.

Edit:

I found script editor and type

tell finder
eject

and i don't know what argument should be after eject

First you go to the terminal and type
Code:
this will show all drives and partitions.

then you type
Code:
where diskXY is the identifier of the drive you want to unmount.

Edit
You can probably create an Automator action and add this to the startup-objects of your account(s).

Problem is that unmount doesn't work - disk is still visible. Moreover disk number is switched, sometimes it's /dev/disk0, sometimes dev/disk1. Also automator does not give me option to eject disk - i cannot select/write/do any action after chose eject disk (or i don't unerstand how it works).

How to put this to startup?

Ok, I tried it this way. I made text file without any extension and put it to StartupItems directory in system with

diskutil unmount /dev/disk1

and also tried

diskutil eject /dev/disk1

Neither first nor second version doesn't work. I have still annoying requester with initialize/eject/ignore option on start of system.

I found something on stackexchange:
Code:

Of course eject might not work for internal harddrives.

Quote:

i tried it myself. The dev/ part is wrong.
if you just write
Code:
It should work. Strange that you don't get an error.

Here i get one, and the hint to try
Code:
instead

Neither first nor second method doesn't work. Still asking about not recognised disk.

I didn't try script yet, but i have similar suspicion that it might not work with internal drives.

BTW: USB part was about USB joypad which is wrongly recognised as not powered device. After pull out it message didn't occur.

Probably i found solution, but my case is more complicated.

There is DiskEject utility, but in my case MorphOS disk is sometimes disk0 and sometimes disk1

From what it depends which number have disk? It rather looks random to me...

Ok, i found similar question on this page and it looks that it is "feature" of MacOS X.
It's really disappointing, because similar mess is not possible neither on AmigaOS nor (of course) MorphOS (or is it?). Even DOS/Windows can handle it and other systems which i know, this is first system which i used with similar problem.

But i don't understand if there is a method or it's not possible, maybe someone with proper knowledge could tell me? I'm confused with these answers...

It would have taken you less time to backup and re-format said drive in the mac layout...

Problem is that disk have 500GB (0,5TB). So there's no other way than next disk with at least 0,5TB free space... which i haven't.

Moreover similar case with partitions will appear?
