I'm not sure if this is an issue or not, but I thought I would post here just in case :)

Here are my disks:

The bug:

This works fine:

address@hidden:~# parted /dev/sdc
GNU Parted 1.8.8
Using /dev/sdc
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print

(parted) quit

This appears to fail:

address@hidden:~# parted /dev/sda

I have no idea what is actually failing.

The odd thing is, I could create the partion map: mklabel gpt and mkpart provided the result I was after, but there were more errors at every step similar to the above error.

This is on Ubuntu 9.04 PowerPC.

Let me know if there is any other information I can provide.

Kind regards,
