Now I'm on the fence Plus vs SE/30
fantastic, yep sounds like you need to get out the schematics and meter and go pin to pin figure out what lines are dead… then post your results.
its probably only like one or 2 lines out. - ya got bit by the cap goo bug.

i'd say you got that quite swiftly, I mailed that out saturday afternoon.
It wouldn't be the mechanism, would it? Maybe a stuck 1.4MB/800k sensor...

yeah when i had it here, i could read 800k/1.4k, just not format or read.
write. oops.
I'm sure its gummed up really good. acted like it was, and I got a nice hunk of fluff on the disk when I ejected it. |)
It was quite dusty inside. it spent years inside a dusty closet running as a mail server I bet that floppy drive hadn't been used since the early 90's it was just a dust catcher.

Ok, so it reads and writes 800k floppies just fine.. Does not recognize any 1.44 meg floppy... This was an upgraded SE, wondering if it's an oddball 800k only SE/30?
Well, that's easy to tell - if you can see a micro switch on both the left and right side, it's a SuperDrive. If there's only one, it's an 800k.
Checkable through the floppy slot? When uni had the board for recapping he got bus errors trying to write to floppies, using a 1.44meg drive, mine is reading and writing 800k fine.
You'll need a flashlight, but, if you look inside the slot on the right side, just below the front edge of the floppy carrier, you'll see two white pins that stick up. Those are what senses if the floppies are 800K/400K or 1.4MB. If you don't have them, then someone forgot to do the SuperDrive upgrade when they put the new board in.

well i was getting the bus errors when i tried to format 1.44 disks.
but i could read them fine,
it was funny when i put in a formatted known good 1.44 it would show up, i could even make a folder.
but when i tried to go into the folder it would lock up and say file/folder does not exist.
i think i tried to format an 800k disk and it would not do it successfully but it would try.
have you tried to format an 800k disk?
i am still super confident the issue is with a trace or 2 on the main board that has suffered from cap goo and rot.
i washed it, so there is no cap goo residue anymore.

I have not tried a known good 800k, I did try a dud, it failed as expected. Than a 1.44meg unknown I tried to format as 800k, it made it 3/4 of the way before it failed. Some point I'll try some other 800k floppies. I was able to copy data to an 800k disk...
Bourns? IWM?
