    You can make a separate ext3 partition and label it casper-rw.
    You then need to delete the existing casper-rw file.
    You can also create a second ext3 partition and label it home-rw.

    This is what I did on a 4 GB flash drive:

    Booted Live CD.
    Plugged in flash drive.
    Started Partition Editor
    Created 1 GB FAT32 partition, (on the left side of the bar).
    Created a 1.5 GB ext3 partition to the right of this, labeled it "casper-rw".
    Created a partition in the remaining space and labeled it "home-rw".
    Closed Partition Editor.
    Un-mounted and re-mounted flash drive.
    Started "Create a live usb startup disk", (usb-creator).
    Selected minimum Stored in reserved extra space, (128 MB).
    Pressed "Make Startup Disk.
    When usb-creator finished, ran "gksu nautilus"
    Selected disk and deleted the casper-rw file.
    Shutdown, removed CD, rebooted.
    Changes are persistent.

    I have found that sometimes they start out being slow to boot but after a few uses they speed up.
    For a while it must have taken about 5 minutes to boot after installing ATI drivers.
    Mine seems fast enough once it's running.

    Re: Increase size of persistence file?

    Hi All,

    I see this thread is quite old, so I know I'm taking my chances on getting any answers back...

    I followed the instructions to create an Ubuntu 9.04 LiveUSB stick. I used NetBootin to create it and worked as expected.

    I do have problems with persistence. I am not able to find the 'casper-rw' file to replace it with a bigger file or to erase it to use the created the ext3 'casper-rw' partition.

    I modified the syslinux.cfg file and added ' persistence' but still no luck.

    Am I missing something? Can you tell me where the famous 'casper-rw' file is located so I can erase it?

    Thanks in advance for your help!

    Marcelo.

    It's been a while since I've used Unetbootin, but I don't think you get a casper-rw file out of the box with it, only with usb-creator. With unetbootin I think it is best to create casper-rw and home-rw partitions.
    I am just now upgrading a flash drive to 9.04 and all my stuff is still there after the upgrade.
