Currently my old LC III is running 7.1 and I want to update it to 7.5.5. I downloaded all of the necessary disk images to my iMac and want to transfer them onto floppy disks via my USB diskette drive. However, every time I try to format a disk on my LC III it only formats it to where 1.1mb is available. Is this common with 7.1 or do I need to do something to change the amount of available space when formatting? Thanks! |

How are you *formatting* it?

Sorry for not being specific. I just popped in a new 1.44mb disk and went through the standard "initialize" sequence that came up. when first inserted. Every time I erase the disk it keeps coming out to 1.1mb of free space. I apologize for my ignorance on the subject, but it really has been a good ten years since I've used System 7 in any form. I really appreciate the help.

I haven't used 7.1 in a few years but in 7.6.1 I get 1.3mb of free space on my floppies. If I remember correctly you could change the disk formats between ProDOS, MS-DOS, and Macintosh - are you selecting something other than Macintosh?

Nope, just trying to format as Macintosh. All I want to do is move the OS 7.5.3 files from one computer to my LC III. It doesn't have an ethernet card and I don't have an SCSI CD-Rom drive or anything, so I'm assuming disks are the only way to go. Maybe I'll go buy a different brand of disk and see if that does anything different.

I've had this same issue formating on a usb floppy drive. I've found that whenever possible format any drive to be used, whether it's an hard drive, zip, floppy whatever, on a system to be used on. For example, 1400 pb running 7.6, I will format the disks using that machine (the performa works as well). Anytime I try off of osx for instance, it puts all of the osx info on the disk as well which makes less space availible. Hope this makes sense and is helpful. niki

That's actually what I'm trying. I want the data to eventually go on the LC III, so I'm trying to format the disk on that machine. I don't even know how to format a disk through OSX, but if anybody here does then that might help me out. It's not the biggest deal if I can't upgrade the thing right now, but my inner nerd doesn't want to admit defeat yet =)

Just thought I'd post and update to let everybody know I solved the problem. Apparently the disks I had were just old and crappy. I picked up a brand new box of disks today and everything worked flawlessly. Now I'm sporting a fresh 7.5.5 install.

I am having exactly the same trouble with an attempt at upgrading a Mac Classic. All of the disks I try seem to be formatted fine on the Classic until I pop them into my USB drive on OS X - it then seems to shred them. I'll try a completely new set of disks to see if that helps as the ones I've been using so far are ancient.

I have a Macintosh Classic running 7.1 at present. Using any of many floppy disks I have (all of which are pretty old, but seem to work otherwise), I initialize the disk on the Classic. Everything works fine. I copy a file, e.g. Notepad File onto the disk and then eject. I pop the disk into my USB floppy drive attached to my MacBook and find: 1. There is a bit of grinding of the head back and forward across the disk, but after a few seconds the disk mounts correctly. 2. I see the Notepad File and can copy it off no problem at all. 3. I can add a new file, e.g. one created in OSX TextEdit to the disk. No grinding or other untoward sounds, although I would say that it seems to take longer to copy a 4K file onto a disk than I expected. 4. I eject the disk from the MacBook - again everything seems fine. 5. I then pop the disk back into the Classic only to get the "this disk is damaged - do you want to initialize it?" message. 6. If I eject the disk from the Classic and put it back into my USB floppy, OS X does its grinding thing again and then doesn't mount it! Doh! Is it my USB floppy at fault, the disks? I am really struggling with this. I was about to go out and buy some new disks (beginning to get hard to find in our local PC store) but wanted to see if I was going in the right direction by doing so. Any help gratefully appreciated.

Quote from: "saaber1970" I have a Macintosh Classic running 7.1 at present. The MacBook is pretty new and the new intel Macs do not run the classic Mac OS even in "Classic". My guess is that it does not handle writing to the disk in a manner that is expected by 7.1 on the Classic. A new file created on the Mac will have attributes etc that would be alien to 7.1. It also probably does not do a correct job of updating the the Mac "desktop" file that System 7.1 requires. All is not necessarily lost. You might try running "disk first aid" on the Mac Classic to see if it can correct any of the problems. Norton also repairs damaged floppy disks. If you have the proper extensions installed in System 7.1 it can read PC formatted floppies and you might find less problems copying files using PC formatted floppies to make data transfers. bill

Thanks for your help. I have recently got a Blueberry iMac running OS9 so will see if I can hook up the USB floppy to it and see if I get anywhere. BTW which extensions do I need to be able to read PC-formatted floppies on OS7?

Any standard install of OS 7 will already have the capabilities to do this installed, called PC Exchange.
