http://www.nybma.com/faq/question3.htm This link is a good link and may raise another problem with your lock that you might not suspect.
A mini-ulock is a mini-ulock. A disk lock refers to the type of core the lock has (what you stick the key into). On the newer kryptonite locks (and the older fuggedaboudits) they used a disk lock core which consists of a series (7-8) of disks stacked on top of each other.
