Internal floopy on Mac SE eject motor doesn't function

Hi All, The disk on my Mac SE could not eject disks. It makes a humming noise, sort of
like trying to pass something, but nothing comes out. It Would read the floppy and load
the system. I removed both the HD and the floppy drive, separated the cage and then
tried them both alone. The HD is dead doesn't spin up or anything. After I cleaned the
floppy and then tried it, the ejector is still no go but now the drive won't even read the disk...
Just gives an X of the icon. I have another 68K mac and it can read the disk, so now I am al
a loss. Does the floppy get it's power from the drive cable? Does it need some other aspect
of the system to power it up. Obviously I need a new drive, but concerned about power.
Thanks for the help.

Getting an icon with a "X" means it cannot find a bootable OS. Are you trying to use a boot disk with a System file on it, such as an Install disk 1 or a Disk Tools disk?

Is the SE floppy drive 800k only?

If you are using a boot floppy, then I don't think the problem is power, but can't offer much else in the way of suggestion, right now.

I can't remember if the floppy drive had a separate power cable - I have a very vague recollection that it did, but may be wrong. You should be able to tell from the back of the drive itself if there is more than one socket.

The floppy drive head may need a clean, and the drive may need to be re-aligned ... which unfortunately is not an easy process and requires specific equipment. It's probably easier to buy a replacement floppy drive (and hard drive) from somewhere like eBay. You could try , but I haven't ever bought anything there so cannot vouch for the reliability / trustworthiness of Herb.

It's too late now, but you may have been better off leaving the floppy drive in the SE and using a straightened paperclip to eject disks (after ejecting them in the Finder of course) before they re-mounted.

I was assuming an existing power cable too, but according to ccadams there is none. Wink

I can't remember and no longer have my dead beige G3 or its floppy drive to check. I just seem to recall a smaller-than-normal power plug on one of the drives in there. I have just checked the old hard drives and Zip drive from the G3, and they all have normal size separate power plugs.

Of course, it is possible that the G3 drive being newer (higher capacity?) did have separate power while the SE drive didn't.

No, I do still have a working beige G3 and the floppy drive has only the one ribbon cable to connect to the motherboard. Its the same cable type as used in my SE (FDHD) 1.4MB floppy disk drive. I don't think there was any difference between 1.4MB and the earlier SE 800k floppy ribbon cable connectors either.

Must have been something else with the smaller power cable.

No damage done and the hint with the straightened paper clip is still valid with jammed CD/DVD drives and such.
Mac users always had an emergency eject paper clip on their desktops, but it may be "new" to others. Smile

At one point I always kept a paperclip hooked onto my keyring. Smile

Thinking about it, it was probably when I had a 3.5" laptop hard drive plugged into my beige G3 as a second drive - the adapter for that was probably what had the smaller power plug.
