The trouble are not the diskettes. I will try to explain better, even if my english is not so good.

The drive is a real external 800K disk drive, I used it since some month ago. I kept the Mac Plus safe without using for some month. When I turned it on today, the system tried to boot from hard disk and gave an error. So I disconnected the external drive, and I see the hard disk systems normally boot. So, I thought, the drive has a trouble.

I checked the external floppy by watching thru the floppy hole: and I noticed: I forgot a floppy in the drive!. But the floppy should be eject by the system, and was not ejected. Maybe - I guessed - the disk was blocked by something.

Anyway, I opened the drive and ejected the floppy manually (to the right, there's a way to pull on an iron block and eject the floppy). I closed the drive again, connected to Mac and booted the system. Then I put another floppy and formatted it. But when I put my floppy icon in the trashcan the drive made a short engine noise, doesn't eject the disk and the icon floppy appears again on the desktop.
