My Trump card has arrived and I've successfully attached and used my GoTek (setup as FLP1_), so seems like the Trump card is operational (shows correct expanded memory too)
But when I attach my 1.4mb floppy drive (GoTek removed for now as I only have a single ended cable until tomorrow) as FLP2_ and try and format a floppy disk (format flp2_test) I get a format failed (not sure it sounds correct either, but as I haven't used a 3/5" floppy for many years I may be wrong)
Is there any knack to formatting a 1.4mb disk or is it likely to just be a faulty drive please? (I'm sure the media disk I tried is good, but did try another just in case). I assume if the ground was the wrong one it wouldn't work at all.
I bought the floppy drive (Samsung SFD-321B) earlier this year but unfortunately I have no way to test it on any other machine
I was wondering if anyone had any thoughts please?
Many thanks
Tony
EDIT: Tried both grounds but no change

Re: 3.5" Floppy Disk Issues
What version is the Trump Card's ROM? I know that older versions work only with DD drives and have problems with HD/ED drives.
Re: 3.5" Floppy Disk Issues
On a Trump Card that is connected to a HD (1.44M) drive and with a HD disk, make sure you tape off the HD signature hole opposite the write protect flap on the disk (or use a DD disk without such a hole). Otherwise the drive will think it's 1.44M, and the FD controller will think it's 720k. But the controller can only format 720k.

I have a confession, I'm a total d*ck
You got me thinking and I realised, I had the media write protected...
(In my defence, if there is any, it's been many many years since I used 3.5" media and I got it the wrong way around)
All seems to be working now, thanks all
Sorry for wasting peoples time!
Thanks

Re: 3.5" Floppy Disk Issues
Hi,
I thought the Trump Card could handle Double Density Disk Drives (720K or 1440 Sectors)
The Gold Card can do HD drives.

Re: 3.5" Floppy Disk Issues
This is correct as far as I remember it too Derek. I only ever had 1.44 Mb drives, and I used them and 1.44 Mb discs with my Trump card.Derek_Stewart wrote: ↑Fri Dec 08, 2023 9:54 am I thought the Trump Card could handle Double Density Disk Drives (720K or 1440 Sectors)

Re: 3.5" Floppy Disk Issues
Well, you can do HD drives and make them think they're DD (that's important because DD drives become more and more impossible to obtain, while second-hand PC HD drives are still relatively plenty). What you obviously cannot do is use them in HD mode on a Trump card. Thus my hint above.
