Comment 3 for bug 572611

I'll just add that I have the same issue - I have tried usb-creator on two different ISOs (one for FreeBSD 8.1 LiveCD, the other for Ubuntu 10.10 netbook), both onto a 16 GB Corsair. This flash drive has had other OS on it before, notably Backtrack 4.

I set the Persistence file to 4 GB in the options the first time, I think 3GB the second time.

The program took 8 or 10 minutes to build the persistence file. I was off doing other things at the time that ended, so it may be that it crashed right at the end of that portion of the process.

This line showed up in my .xsessions-errors - perhaps it is indicative of something. The lines around it were not relevant.

And this is the end of .usb-creator.log:

Looking at the mounted flash drive, it appears to have a complete system on it. I will take it home and see if it actually boots my netbook, and report back.
