The way I remember is that the Fujitsu Eagle is the 2351 and the Super eagle is the 2361. Fujitsu did make 8" drives but the were not called Eagles around the Northwest. The 23XX (2316, 2333 etc.)series were nice 8 inch drives. I have also had some 14 inch Fujitsus but I cannot remember the series numbers but they predated the Eagles. Paxton Astoria, OR
