A4000: df0:??? on desktop, how can I solve it?

Hi guys.

I got this A4000 last week chock full of problems! The latest problem I was going to fix is that no floppy drives work on the computer. DF0: shows up on the desktop as "df0:" even if the floppy drive is removed or connected. Any external drives do not work at all as they do not show up on the desktop.

I was told the 8520 chips where burnt and I got replacements from Vesalia today which clipped in the sockets easily however the problem is the same! So is there any other chip that needs to be replaced or can the floppy drive be disabled completely to remove the annoying df0: on the desktop?

Thanks!

No the floppy cable is connected the right way, very weird. Whats the point of having an Amiga if you can not add four floppy drives?  :lol:

I am using a straight cable without twist and it is jumpered as df0.

Strange.

Aha, that may be the problem since I do not have the original floppy cable, I am using a PC one as a substitute.

No the floppy is completely dead with or without HD connected. And it shows up as "" on the desktop if it is connected or not.

I am going to try new cable tomorrow, I have had so much problem with this Amiga, I think it is a good idea if people do not store expensive A4000 towers with PPC cards in a moist cellar :cry:  :-)

Cool!

Thanks I am going to post my results here when I am finished testing!

[cv643d]

I am definitely going to try that later today! :-)

(busy with a clients website at 23.32 in the night :-(   )

OK now I tried it!

J351 is open
J352 is external

Disconnected internal floppy.
And got an external drive in the floppy port on the backside.

And I still get the same problem! "df0:" on the desktop.

Maybe the sockets for the 8520 are having some contact issues with the chips?

[cv643d]

Yes exactly like that in the boot options.... Going to take a closer look at my system tonight!

[cv643d]

No that is the problem :-) .. I mean the floppy is completely dead. Ok it gets power but the drive light never reacts and nothing happens. Amiga appear as if no floppy is connected whatsoever.
