Get rid of "The disk you inserted was not readable"?

[SS01]

I have OS X tri-booted with Windows and Linux. It is on the same drive as Linux's /home, with Windows being on a seperate 160GB drive and Linux applications on a 60GB SSD. Whenever I boot up, I get "The disk you inserted was not readable by this computer" twice, once for each of the two Linux disks. Is there a way to make OS X stop "seeing" these disks? Thanks

or choose the hide option in chameleon setup

or choose the hide option in chameleon setup

If I'm not mistaken (then apology), "Hide" option hides a disk from Chameleon's own boot disk selection menu. While the question was about OS X trying to mount disk with filesystem it can't read (when OS X is already booted and running).

I'm sorry that I'm bringing back this old 'thread', anyway my situation is that.

I do have two volumes, one with Lion and one with an ext4 partition.

Unfortunately I cannot get the UUID through 'diskutil' (same story for 'disk utility'):

Do you have any hint on how I can prevent 'disk1' to be automatically mounted?

diskutil info $(df / | tail -1 | cut -d' ' -f 1)

 

from terminal

This is the result:

I can get the UUID of the HFS+ partition even with "disk utility", but I need to prevent the other disk from mounting (ext4) or I'll get the "disk you inserted is not readable by this computer" message anytime I boot on Lion. Thanks tho.

[aphex6b]

one option is to install a third party filesystem-driver that has Linux filesystem support so you'r able to r/w disks in Mac OS, then you'r able to get the UUID and put that inside /etc/fstab so it doesn't auto mount on each boot. There is a better option when using MBR / Fdisk scheme type disks with linux installed onto them and this involves creating a additional FAT32 partition just before the linux 'slice' so OSX will not complain on every boot, but I'm unsure about how to do this with hybrid type disks layouts  

[Innopeor]

A tool called "Paragon ExtFS" did the trick. I have now read/write permissions on my ext4 partition and error message is gone.

A very gentle guy sent me a PM and he let me know that there is an open source alternative too:
