Yes, they're installed and I have no problems mounting FAT16 images. It's something more low-level, since I can't even read the device (/dev/sde) when the floppy has been formatted by the MSX. And the other way around, if I copy a formatted image directly into the device, it works on Linux, but not on the MSX. On Linux it says it can't read sector 0. So I suspect it's very low-level, but I don't know what exactly.
It's not really a problem for me, since if they work on the MSX it's fine. It's only that it'd be easier for me to use the USB unit in my PC to copy files. I guess this modern USB unit is quite picky with the physical encoding, ouch...

Maybe the head on the floppy drive of either your MSX or PC is misaligned.

Thanks for the tip, Grauw! I'll have a look, but I'm not really confident about my mechanical skills Big smile

Hi Guys,
I think my question fits in here about copying .dsk images to a real disk

I am able to copy most .dsk images to disk but i run into an error when i try to copy full 720kb disk images.
For instance if i download a pre-patched sd-snatcher (SD Snatcher [T-En by Project Melancholia 0.92]) there are 4x 720kb disk images.
When i try to put a disk image into disk-manager it says "not a valid ms(x) disk image"
I tried to ignore and write to disk anyway but it doesnt seem to do anything.

Does anyone know howto copy full 720kb disk images? Murdoch

Disk manager is a tool for dsk files to a real floppy and vica verca.
With fdload is for sector based files it is a msx file
https://www.msx.org/wiki/FDLOAD.
I use the mega Flash rom for this fdload is installed on the mfr, i don't know if there are emulators on pc that use a real floppy drive mfr is emulated. Fdload operates as follows with the mega Flash rom
Go to command.com (msx dos) type b:
Then Type fdload
Type the the following command:
B: fdload (name of the disk example ds1.dsk) c:
B:fdload ds1.dsk c:
Enter and the dsk file copies to a real disk in the msx.

Note
A: is mfr strorage
B: is sd cart
C: floppy drive

I've din't try sofarun, but with sofarun you can put dsk images to a real msx floppy disk. this is done on a msx and flash strorage like mfr carnove2 e.c.

Hi Andre,
Thanks for the answer.

I do use disk manager to copy a msx .dsk image to a msx formatted floppy on pc and that works on all .dsk images i have done so far.
For some reason when i try to do that with an already patched .dsk image like the english translation disk of SD Snatcher it says "this does not seem to be a valid ms(x)-dos image!"

I cannot try it (yet) with a mega flashrom because i don't have one at the moment LOL!

disk manager does't work with sector based games, maybe if there is an msx emulator thats use a real floppy drive, u can try to use msx on the emulator as a msx and save the sector based files like that to real floppy,
cos mfr is emutated maybe a bit of a detour perhaps it works.
( i use bluemsx that does'nt support real floppy)

I can put dsk files on a real disk if you live near zwolle

Hi Andre,

Thanks once again.
I did find an old topic with the same problem here

I will try to use other methods to get the image on floppy first. :)
