The install disk did not come as standard with workbench 3.0 unless you bought the machine with a hard-drive already installed. I had this problem when i first put a 356mb 3.5 HDD in my A1200. It cost me £220 at the time, which was a bout the going rate. Still got the drive. So u will need to get a copy of the disk or HDtoolbox off Aminet
