HD went bad on an old LCIII (system 7). I have a replacement drive but it isnt apple, so it isn't recognized by any disk tools (drive setup, etc). What I think I need is a boot disk that has a patched version of drive setup. I have found some floppy images including the Network Access 7.5, and a few others, and I have found patched versions of drive setup util. Most of these were compressed,encoded files so I have the latest Stuffit Expander for both XP and OSX. I have tried several different utils both on XP and on OSX for creating mac floppies from those image files, and they have all failed for one reason or another. Many of those old utils don't work on XP, sometimes the imaging process fails (insufficient space), and if it doesn't, the resulting disk won't boot the system. I have even tried copying my original, working disk tools floppy to another floppy using OSX without success. Disk Utility seems to create images from a system 7 floppy OK, but I can't get it to put than image back onto a floppy successfully. What am I missing here? I think I need a step-by-step of how this is done, preferrably on OSX. |

Mac OS X can not create, copy or reproduce 800K format Mac floppies. It can create 1.4MB format floppies for older systems. So make sure you are working with 1.4MB floppy images and copying them to a 1.4MB floppy disk. If your OS X machine has built in SCSI or an added SCSI card, you can format your hard drive in the OS X machine, making sure you format it as HSF and not HFS+. If your LCIII has a CD drive you can create a bootable CD in OS X and boot the LCIII from that. Creating boot floppies for older Macs from Windows and Mac OS X machines has never been easy or reliable. I am not aware of any fool proof step by step instructions that lead to success. It is more a case of patience and persistance. If possible begin with new floppies formatted for Mac. Do a fresh format on any floppies that were PC formatted floppies before starting the copy process. Mount the floppy image and try and slim it down. Readme files etc can be discarded. Mac copy routines are very fussy and ensuring there is enough extra space on the floppy to allow for a bad block or two can be helpful. bill

I just have the LCIII and a wrongly formatted HD. The macbook I have access to is a new laptop. No way I am going to try hooking a whiney old scsi drive to that. Other than that I have six or so PCs, all with XP or linux. No way to talk to the old drive. I have an iomega usb floppy that works great on either PC or macbook. I have the original system 7 disk set including the Disk Tools disk. They look to be 1.2M format. I have mac disk images that claim to be 1.4M, and some that look to be 1.2M. I have a bunch of PC floppies, formatted 1.4M. I don't have a lot of experience with mac, so I may be missing simple things, but there has to be a way to get from A to B with the materials I have on hand. If I could just duplicate one of my existing mac floppies I'd at least have a clue as to what works. As a start, can an LCIII boot disk be created on a PC formatted 1.44M floppy or does it need to be in another format first? The Disk Utility on OSX does not have any feature that says format a floppy. It does have erase. If I erase and specify standard OSX format, is the result the same HFX format that the LCIII wants?

You will not be able to create a bootable Mac floppy on a PC formatted floppy. Although copying a floppy disk image to a floppy should correctly format the floppy, it often fails. You should format the floppy before you make a copy from the image. You are running newer hardware than I have and are also probably running a newer MacOS than I. I will dig out my external floppy this evening and see what options I have available and which would be of use in your case. bill

Everything I have tried to duplicate or manipulate LCIII floppys using OSX 10.5.8 has been a pathetic failure. But hey, it looks good doing it... I have been able to image copy those HD mac floppies onto PC formatted 1.4M floppys using the RawWrite for Windows utility. I did get several failures doing this so the process isn't perfect, but my floppys and the PC I was using are pretty old the floppy drive has had problems even with PC files. Once I find a floppy that works though, I can re-image it over and over. Now that I have working copies of the Disk Tools floppy and Network Access floppy, how do I get the patched version of Apple HD SC Setup onto one of those disks? I tried using stuffit to expand hd_sc_setup_735-patched.sea.bin and drag & drop it onto my already working floppy. Once again OSX pretends to know what it is doing, but it proves to be a charade. The disk boots on the LC OK, but the icons are messed up. It seems the file and/or its resources have not been copied correctly. Rather frustrating.

The resident geniuses down at the apple store offered their sympathies since they had no training in archaeology, grampa. The only way I see this happening is if some kindly soul is willing to use a working LC to put the patched Apple HD SC Setup onto a bootable floppy for me. Or I could email an image of my Disk Tools disk and the patched version of that util. It would then have to be put onto a floppy using the same rawritewin tool on a PC, booted on a mac to add the patched util, re-imaged with rawritewin, and emailed back to me. A lot to ask, I know.

I was able to copy and delete individual files on a Mac 1.4M floppy using the abandonware tool Executor running on XP. The Executor emulator does not need any Mac ROM, and it already includes Stuffit 4. First I duplicated my Disk Tools disk using RawWrite (rawritewin.exe) on XP, then I added the patched version of Apple HD SC Setup. Bad news is the hard drive is still unrecognized. Lido7 also says there is no disk out there. Funny thing is every time I hit the button to scan I can hear the disk stepper.
