Hi there!
Got the same problem with my scandisk pen drive.
i needed to create a bootable image of ubuntu, and when i did PowerIso asked to format the pendrive. I said yes, installed ubuntus. All great.
Now one problem: my scandisk went from having a 8gb capacity to 700 mb capacity. Also, it no longer has the exe and the capacity to add password protection.
So how can i format both pendrive to restore the 8gb capacity, and also restore its password protection property???
thanks in advance
