Hey guys. I have spent two days working with an 800k floppy drive and I can't seem to get it to behave properly. I won't bore you with a detailed play by play but I'll summarize what I have done:
1. Disassembled, cleaned (99 IPA) and relubed ejection mechanism
2. Cleaned heads with 99 IPA
3. Per the Dead Mac Scrolls, I repositioned the 00 Track sensor
4. When that didn't work, I replaced the 00 Track sensor and lined up with hash mark on floppy frame
5. Got the drive to initialize disks and read/write those, but will still not read disks initialized in another drive
6. Did the realignment procedure outlined in Dead Mac Scrolls, loosening, turning, and tightening the stator motor housing and trying again. Tried this many times.
I worked on realigning the drive for over an hour last night and I could still not get it to work right. When I initialize a disk in the drive, the drive will read it. The drive will also write to the disk so that means the heads are fine. However, it will not read any other known-good disks initialized in a different drive. When I put foreign disks in, the head doesn't even seek. The drive spins and it asks me if I want to initialize. At this point I am out of ideas. I don't own an oscilloscope, I'm doing everything by hand. Does anyone have a suggestion to get this thing to work right?
