Message-ID: <12683@skye.cs.ed.ac.uk> Date: 17 Jun 91 13:58:27 GMT Sender: nnews@cs.ed.ac.uk Reply-To: nick@lfcs.ed.ac.uk Organization: Sally Fowler Rat Pack Lines: 26 Just for kicks, I attached a 160Mb disk from a Hewlett-Packard HP9000 workstation to the back of my Mac Plus, to see if Silverlining would recognise it. Lo and behold.... Nothing. So, I thought I'd try it on an SE/30, since the Mac Plus's SCSI implementation is known to have problems. And, after a false start or two, I had a 160Mb Mac disk running on an SE/30 (the false starts relating to SCSI tests which seem to prefer a formatted, initialised disk). One puzzling thing: I can't make the disk bootable. Copying a System Folder to it doesn't work. Running the Installer on it doesn't work. Is there something special about HD's for Macs which this alien doesn't have? I altered the SCSI numbers and startup device, no joy. The disk goes active for a second at startup, but the SE/30 always chooses its internal disk. Just curious - for now. If I could make the thing bootable, does this open the door for nice cheap hard disks which aren't intended for Macintoshes?
