You probably have a "universal" cleaning cartridge.  The algorithms that
the drive uses is different.  

HP guarantees that their manufactured UCCs will last at least 15
cleanings on an LTO-1 drive and at least 50 cleanings on later models.
(But they'll probably last 52 or 53 cleanings).  Some libraries can
detect when a cleaning cartridge is done, but I don't know any backup
programs (like Networker) that can do the same.

Yes.  You can change the cleaning count at any time.
