Hi, Tim.

I got the same corruption problems using the Ubuntu Startup Disk Creator
with a 4GiB persistent casper-rw. The Ubuntu USB creator already limits
the size of the casper-rw container file to 4GiB.

I created a FAT32 partition 10% larger than the iso and used the rest of
the 8GiB stick for the second ext3 partition. We had conversations about
ext2 vs. ext3 before when I was doing this for NuGO: I had lots of
problems getting filesystems to sync from NuGO-Linux USB-sticks. In the
end, I used ext3 because it will redo ext3 journal transactions.

Bye,

  Tony.
