i think this is the last disk manager fujitsu created, licensed from ontrack systems. now fujitsu no longer provide support for 8.4gb hard drive barrier. if this doesnt work then try www.ontrack.com/fujitsu. you can buy the licensed version for $14.
this was tested on ibm 2600-B0A w/ 8.4gb hd capacity limitation and 40gb fujitsu hd (2-12-2006).
