Isit possible to use my KRYOFLUX to write BBC disks?

Post by spiny » Fri May 01, 2020 11:25 am

Hi All,

I'm about to add a 3.5 floppy drive to my BBC Master, so ideally I need some disks to check it's OK (I know the drive hardware is good as it works flawlessly on my Atari ST)

I have a KRYOFLUX and plenty of disks, but the DTC software doesn't seem to 'know' how to write the common *.ssd / dsd images I can find.

any tips ?

cheers!

I've not managed to get Kryoflux to write BBC discs either.

Best way for 3.5" disc is to use OmniFlop on an XP PC with an on-board floppy disk interface. You will need DD discs (with one hole) rather than HD discs (with 2 holes).

Ah, didn't realise that would also work :)

I'm not short of disks:

and have an XP machine specifically for writing disks too, so all good :)

Well, that did the trick, many thanks :)

Got Exile running on real hardware, nice!

This is how I write floppy discs, but one thing you need to know is that formatting them on Omniflop doesn't usually work properly. I find I have to format them on the BBC first, then write them using Omniflop.

However, you don't seem to have had that problem! =D>

If you do want to get the kryoflux to attempt to write them, the way to do it is to use the HxC floppy Emulator Software to convert the SSD/DSD into a kryoflux stream, then it'll write that to the disk. It's a bit hit-and-miss in experience!

I was at one point compiling an Excel sheet of PC motherboards that would read/write/format single density floppy disks.

It's interesting to note that there seemed to be some that would read and write but not format which was odd, but you could of course get round that by formatting on the beeb first.

If people want I can post it here.

Though I haven't updated it in a while as greaseweazel can pretty much do the same job on a modern Windows / Linux PC or Mac.

Cheers.

Phill.
