Hello,yes it spins-up,the first hdd is hitachi 12mm the second is 9.5 ibm tsar.
you cannot run the 9.5 ibm in a t20 so on.But the 12mm will work in the t20 so on. if you jumper it nothing!!!!take jumper off,shows on screen>no hdd attached! Is this standard with IBM?IT seems 12mm is the only hdd for t20,23.
