Macintosh Classic Floppy The drive ejects every floppy disk

[Moltobene]

Hey Guys,
my Macintosh Classic ejects every floppy disk, on boot the finder logo appears briefly for a half second, then is ejects.
The Mac is fully working. When I start it from the hard drive and insert a diskette it wants to initialize or eject it. When I initialize, the Mac says formatting is incorrect.
All capacitors on the analog board were replaced.
Any Ideas?

Hi Moltobene,

Have you checked the eject gears for any damage, has the drive been serviced (old grease removed and replaced and drive heads cleaned with a cotton tip)

 

[Moltobene]

Its all clean, an the head ist moving on formatting disk.

Probably a dirty disk used once.
Old units can be contaminated and dirt is left on the head.

Cleaning the head again should make it work again (look at the head for black spots)

 

[Moltobene]

I cleaned it again, same result.

Can i replace ist with a Macintosh SE drive FDHD ? or will i Damage the logic board?

Any 3.5" floppy of this model should work fine in the Classic

Sounds like the zero track sensor is out of alignment.

If you ever get a new one and don't need the old, I'd gladly take it. Best of luck here.

Ok the Se drive works.

 

[Moltobene]

But i got a new error

Not sure what that says in German.

My German is very, very rusty, but I think it is saying that Appletalk software cannot be found, so Localtalk will be used instead - then it compares this action with Germany’s annexation of Austria (Anschluss)…but I could be wrong. As I said, my German is very, very rusty.

 

[Moltobene]

Is there any driver or software i can install?

There may be some sort of preference set on there in the Network or AppleTalk control panels for some non-existent interface, perhaps Ethernet. Trashing Ethernet extensions or using those control panels to select “Built-In LocalTalk” will likely solve the issue.
