Ah sorry I didn't know it was included on the software disk. In that case I would opt for Taj's idea. 
@ Cammy, Chances are he/she is running a KS 2.05 or something inside that A600 so the maximum drive that will work on that Kickstart is 40Mb.
Just to bust this myth, I have an A600 with Kickstart 37.300 (2.05) and run a CF 4 gig card just fine in it, partitioned into two 2gig drives, works flawlessly.
Also Workbench 2.1 is worth putting on, most of the advantages of WB 3 without a ROM change.
Install disks for 2.1 can be found on Amiga forever.
