|Do you get an Extend Volume option? If so, then this should work as well.|
The drive you copied may have had protections built into the firmware of the drive and you copied those over when you completely copied the drive.
If that does not work, you may need to use the same software to copy another 8GB USB drive onto it in order to correct the problem, preferably the same model and size.
By the way, if that software was a free download, I may have some use for it and a link would be very much appreciated. Thank you and good luck.
You have to be a little bit crazy to keep you from going insane.
