Strange A1200 floppy disc problem

[acharris05]

Hi all, I need some advice.  I have an Amiga 1200 with a 8 Mb Ram expansion board and 240 Gb HDD.  The amiga works fine from the HDD, but I can't get the 1200 to read any floppy I put in the machine from either DF0: or my 2 external floppy drives.

I tried putting a floppy disc game in the drive to start the Amiga, so that it will bypass the HDD and load from floppy, but after a few seconds it will switch to HDD and load WB up.  

I can format the floppy discs in any of DF:0, DF:1 and DF:2, but I can't seem to read or open a disc to viewthe contents in any of the floppy drives.  Also I am getting like a fishy smell from my A1200, which I would assume means that something is burning.

So what part of the motherboard controls the floppy read access, and what is the fix, as I am not fully up on the internal workings of a A1200 only know basic, though I do know PC's. Any help is appreciated.

Thanks for the advice.  Good thing I got a few A1200 knocking around all working.  I will have to swap one over.  Thanks again.

Hi, and thanks for the replies.  Yes I will use another 1200 and transfer the HDD and Ram expansion, but I was looking to see if there was a simple solution to this problem, and also to learn a little more about the A1200 and what chips control what, as oppsose to just swap amiga's and never learn nothing about the working of the Amigas.
