Try using the HDToolbox program of release 2 or release 3 of AmigaOS (on the Install disk), have a look at what partitions show up and where abouts on the graph they show up. I've definitely used the 2.0 release of HDToolbox on 1.3 so I know it works, and probably the 3.0/3.1 version works too. Is it presently setup as just a single partition utilising the whole drive?
EDIT: INSTALL DISK doh!
