Hi,
@iMacMiga
Sorry that I cannot help ypou with your problem, but if you own the original WB 2.05 disk set, there should be a disk called "Install" containing the required harddisk-tools.
But BTW are every A600 computers equiped with an IDE interface, so you could add an IDE disk to every A600?
I try to get an A600 via eBay, because it is such a nice little machine and I could sell my ugly A500 if I could get an A600. It would be cool to add a HD to that Amiga, makes it much more usefull.
