First time in the world of the classic Macintosh, I have a Macintosh Classic with the SuperDrive (1.44mb).
I did a lot of work to make the auto eject mechanism functional again, but I have somehow managed to cause more problems. Previously, I was able to read and write to floppies that were initlialised on the Classic in a USB floppy drive attached to my iMac (also tried with PC software WinImage). Now, they are completely unreadable, except when used on the Classic, where they work fine.
I have been using brand new disks, so am ruling them out. If I format a brand new disk on WinImage with System 7 software, the Classic won't read it. If I use a disk I initialised on the Classic, and reformat it in WinImage, the Classic only sees the previous volume label of the disk - still works, as if it were never reformatted! Reformatting old disks on WinImage results in a track/head error, unless I also specify an image to write to it (System 7 software).
I assumed this was a head alignment issue, but I've tried everything (without having an oscilloscope) to get it readable again outside the Classic, with no luck. Is there something I am missing? By physically manipulating the head and disk, I was able to force the Mac Classic to read the correct volume label just once - and got an error message straight away. I have cleaned the heads repeatedly, again they work fine with disks initialised on the Classic.
I'm willing to buy a new used drive at this point, pulling my hair out. Unless there is something I am missing.
