Also after rebooting the system I have two new icons :-
CDH0: ####
CDH1: ####
This means you (or the previous owner of the HDD) successfully created two partitions.
however if I double click either I just get the response from WB :-
icons have no default tool
This means the partitions are not formatted. Click a partition once and choose "Initialise" from the menu to format it.
is there other hard drive prep softwre available?
Try HDInstTool from Aminet. It works on Kick 1.3. You might need to adjust its tooltypes to match the name of the A590's SCSI driver. The default is scsi.device. I don't know if there are different names for the XT and the SCSI part of the A590.
Bye,
