Floppy Drive Specs.

[X-ray]

On a related note, I would like to know if I can use an A4000D floppy drive in my A4000T.
I want a spare A4000T floppy drive. Any advice /suggestions / horror stories?

What is the difference between the 357A and 354? Tried to Google it but got no joy.
And why do we have these little PCBs in our A4KTs?

@ PaSha

But what I don't understand is if we have these PCBs why can't I just plug in any old PC drive? And if I took the PCB out, would I then have a machine that behaves exactly like an A4000D...would the floppy header be the same?

Back in 1996 I bought a plain floppy drive from a PC fair and tried to use it on my A4KT and it didn't work.

I just did some experiments again. I took the floppy drive out of my PC and put it in the A4KT: no joy. The access light doesn't even come on and I get the 'unreadable df0' icon in Workbench 3.9.
Just for giggles I put the A4KT floppy on the PC and the same thing happened...no access at all. Whether there is a disk in or not, Winblows says please insert a disk in a:

The A4KT drive is a MITSUMI model D359T5 (Newtronics Co. LTD).
The PC drive is an ALPS ELECTRIC (made in Malaysia). The only number on it that could be a model number is DF354H090F.

So...what gives?

Edit: I didn't change any jumpers on the Amiga side, just changed one drive for the other. Same with the PC. And the cables are keyed so I can't connect them wrong even if I want to.

My PC drive has just solder blobs, very small, on a very small gap. This isn't one I can jerk around with, but next time I'm at the fair I'll pick up a drive for £5 and test it.

It annoys me that even though we have these adapter PCBs there must still be all this fiddling under the cover.

Chaps...

I am still looking for a working spare floppy drive for my A4KT. If anyone is selling one, I am interested. (it would be a bonus if it is a HD drive). I am having no luck with PC drives.
