Hi,
The workaround asks you to disable persistence completely right?

I wanted persistence and found a solution to the problem. To use a later version of 'usb-creator' v0.2.12 which has no problems with persistence.

If you want persistence, try using that version of 'usb-creator'.

Thanks,
Praveen
