[SOLVED] Access OSX Home folder with Ubuntu Live CD

[Ricardobrusd]

Hi,
I am trying to backup to DVD some files in a problematic OSX partition using a Ubuntu Live CD (7.10 Gutsy Gibbon), however I cannot access my home folder.

My OSX partition is HFS+ Journaled, and I can`t modify any files. Also, I cannot access OSX or install Ubuntu.

I saw some threads about creating a UID that matches the OSX`s User ID , but I don`t know if it`s possible using a Live CD and is not clear to me how it should be done.

If it`s not possible to access this files, can Gparted copy my entire partition to a external hard drive? Will those files be accessible in OSX ?

Thanks for the attention (and sorry for any grammatical error )

the files in your home folder are "owned" by a different user than the Ubuntu LiveCD user. Therefore, the permissions on the files do not allow that other users access.

You can start a root nautilus window to access the files:

sudo nautilus

I've alredy tried the "sudo nautilus", but I can't access my OSX partition within it. The partition is mounted on my desktop, but doesn't apear on nautilus.

Am I supposed to mount the partition again?

Let me clarify what I meant.

I am able to mount my Macintosh HD, my iPod and my external dvd drive on my desktop and on the file browser.

But when I use the command "sudo nautilus", I cannot "see" or mount any of those volumes within the file browser window, even if they are mounted on the desktop.

I'm not very experienced with Ubuntu, so I might be misunderstanding something.

Help would be greatly appreciated ( and is urgently needed :lolflag: )

The ubuntu can not access the HFS+ volume.For the HFS+ you need a ubuntu package named as HFS plus.

The HFS+ package shoul be already present in the LiveCD.
Your MacOSX HD should be mounted in /media
It should be /media/disk or /media/disk1 according to your partition map
Just check if you see it with
ls /media/disk
What do you want to do? Do you want to back up some files?

Mounted drives are mounted in /media so you have to navigate to /media in your root nautilus window. Also, note that you will likely need to open two root nautilus windows one for the source and one for the destination.

hfs+ access is enabled by default in Ubuntu.

In a live CD environment, it may not matter much, but you should get in the habit of using gksudo (and not sudo) for graphical applications. The proper command is
gksudo nautilus Even if you mount the drive and locate it in /media, you will not be able to modify files, even as root. Linux is not, as far as I know (and I've done extensive Googling on this topic) able to write successfully to HFS+.

You will, however, be able to deal with the files on a read-only basis and should be able to copy them to an external drive and then burn them to DVD on another computer.

+1, but it is that it cannot write to journaled hfs+ partitions which this poster is likely dealing with.

Actually Linux can write on HFS+ but not on HFS+ Journaled. You can disable Journaling from inside MacOSX.
In Linux (with parted) you are able to shrink a HFS+ Volume, but you can't generate a HFS+ File System.

I ckecked and found that for unjournalled hfsplus, I had to manually mount it on /mnt then it was writeable, but not when automounted on /media.

This is strange. I can do it, from a Terminal and starting Nautilus as root.

I finally could access my files ! I`m so relieved. :cool:

Thank you so much for the help.
