An Amiga 4000 HD disk drive, in Amiga 1200 ?

[Astral]

I know it is electrical and software compatible. Is it a DIRECT swap job with everything fitting correctly, including allowing the case to close properly? If not, what modifications are involved?

If you have a Commodore A1200 it will be electronically compatible.

However most A4000 drives are 1,5" high, thus the case will not fit together properly.

If you find a 1" high Amiga HD drive, you can get the case on, but the eject button will not fit properly and you must do something about that.

Hi, are you talking about a high density floppy drive, or a hard drive ?

Modification that need to be done is: remove the front plastic, bend away aprox 4mm of the top metal (bend it 180degree over itself, in case you need to reverse the mod this will allow for that contrar to cutting the metal). If you can live with it the eject button usually doesn't have to be changed.

What I found out was that the HD diskdrive draw a bit more power that the DD... in my case it resulted in disk being read just fine but delete/edit/copy or format a floppy and it would go NDOS.
