Floppy drive (again...)

scaf · 20 March 2003, 13:30

I finally found a floppy drive that works in my a2000.
it's a mitsubishi MF355F (1.44Mo)
It works with ks1.3 and wb1.3
It works with ks3.1 and wb1.3
But, with ks 3.1 and wb3.1, even if a disk is inserted, the system says "No disk in drive".
I don't think it's a hardware failure, 'cause the drive works with wb1.3.

Does any1 know where it comes from ? And how to solve the problem ?
(it should be a system problem?)

Perhaps the Diskchange-Signal is not correct. What is happening if you execute the diskchange-command from shell? If the drive recognizes the disk, you have to swap line 2 against line 34 of the floppy cable or check for a jumper at the drive saying "rdy/dc".

I tested many drives with my A4000 but none of them worked 100% for me so I got myself a Kylwalda-Controller. After installing this together with a Teac-Floppy I encountered no problems yet.

The DC signal is correct : the drive works very well under workbench 1.3 (yes : workbench, and not kickstart - it is 3.1- )
Under workbench 3.1, the drive is found, but never detects any disk.
The diskchange command does nothing.

The jumpering of the drive is correct.

Hmmm. Sorry. I´m out. No idea why this doesn´t work under 3.1! :eek

Hmm, have you checked some game, yet ? Do they work ? Especially some NDOS game disks ?
Maybe your drive has diskchange signal correct, but is missing the ready signal ?
WB 1.3 isn't dependent on the ready signal, but maybe for some reason 3.1 is ?
Also, are you sure you have Kick 3.1 and not 3.0 ? Maybe you try to run WB 3.1 und Kick 3.0, which could give problems ?
Also, no further ideas - sorry...

new : the floppy drive works under wb3.1 !

Configuration i used :
kick 1.3 and wb1.3 : drive ok

now, the machine is softkicked
kick 3.1 (40.63) and wb1.3 : drive ok
kick 3.1 (40.63) and wb 3.1 (40.42) : no drive
kick 3.1 (40.68) and wb 3.1 (40.42) : drive ok

Well... do the kick 3.1 40.68 exists as chip for A2000 rev 6.2 ?
