I don't know what you mean by no luck so far, it isn't an active tool, more one of inoculation, read the information I posted and that on the page where you got the tool, it outlines what it does.
I don't know what it is that you hope it was going to do ?
The fake systemvolumeinformation folder was created by malware and that won't have changed and it isn't something covered by flash disenfector as the information in the link you got the too from, that is why I said you will have to remove it.
So I would suggest that you remove this J:\System Volume Information\ folder and its contents. Look for an autorun.inf file (most likely hidden) and remove that also, they shouldn't be on hard disks.
Did you check for a hidden autorun.inf file before and after running flash disinfector on your external drive ?
The file should be gone and a folder called autorun.inf created and that prevents the future creation of an autorun.inf 'file'
