Faulty Flash USB?

It depends on the specific version of DiskDirector that you have.
For V10, you just right click on the disk and there's a Copy MBR
item. Then on the target disk you can rwrite that MBR. For
DiskDirector 11 they seem to have removed this nice
feature and instead you have to "edit" the disk and copy
the right number of bytes representing the MBR. What a crock!!
That's the sort of UI regression that's a firing offense. But I digress :-)
Check the on-line help for the version you have and the procedure
should be documented. I had both V10 and V11 and used V10
to do it since it was dead easy. There are free trial versions
of DiskDirector. I'm not sure if this feature is enabled in the trial
version.
