Can somebody explain the mysteries of IT to me

Thanks Jack for posting the link. I think I am familiar with the file. My problem is to find out how to change it from 4GB to e.g. 10GB. There are commands like

cd /media/mint/casper-rw

dd if=/dev/zero bs=1M count=10240 >> casper-rw
　
resize2fs casper-rw

Problem is, they don't work. And another method where you use Gparted to extend the file destroys the Grub and I have been unable to fix that bugger.

Maybe some Linux geek can have a look at those commands and tell me what's wrong with them.

I will leave you alone.
Please post back when you got it figured out.

I will Jack. I may just abandon the project. It is just a fun project that serves no particular purpose. I will make a last attempt and ask my buddies at the Mint forum for help.

How I fix stuff in IT:

The voodoo part I'm still working on

Well, the good news is that I finally got a Casper-rw file that covers the remainder of my stick. But it only works on the 16GB stick. The installer allocated it there automatically. I would have loved to get it on my 120GB stick too, but not yet. Maybe some more experimenting will do it.

Probably a dumb question because I don't fully understand your setup...
You are running Mint plus other programs on the USB flash drive so what boot manager are you using?

I know with grub4dos, programs need to be contiguous and sometimes need to be preloaded into RAM if they are stored on the USB in a non contiguous fashion.

Michael, I use the Universal USB Installer. That installs the system automatically (from an iso) with 3 clicks. Runs great and is very fast - especially for the internet.

Sorry I've never played with the Universal USB Installer. I wonder if you get the same problems with YUMI.
IT's a mystery to me as well.

There is really no problem with the universal installer. The only mystery was that it did not use the whole stick for the casper-rw file - at least not on sticks larger than 16GBs. That restricts you in the amount of data you can put on the stick. But now I managed to get 12GBs and that is enough for the purpose.

I'm surly confused. I have heard of a storage device being to small but never being to big to install things.
