Hi all,
I installed a GOTEK SFRM72-TU100K in my Philips NMS 8250. I didn't understand how to use the software, that came with it, so I downloaded software from the IPCAS website (Batch Manage Tool V1.40). After that I succeeded in formatting an USB-drive, copy disk-images and files to it and even reading these virtual disks with my MSX computer. But still I'm encountering some problems:
- on my MSX I can only read one of three disk images. When I select disk 00, 03, 06, etc. using the two front buttons, I can read and write to the virtual disks with, according to the IPCAS software, serial numbers 000, 002, 004, etc.. This means I am able to use only 33 of the promised 100 virtual disks on one USB drive. When I select any other number on the emulator (01,02,04,etc.) I will get a "Disk i/o error" when I type "FILES". The diskimages with odd numbers, as well as the diskimages above number 066 (as viewed with the IPCAS software) can't be adressed with the fdd emulator in my MSX.
- I can't copy files from the real disk drive (in fact an old PC drive that I have put in my MSX as b: drive) to the emulated disk drive. Well, I can copy one file (using copy "a:example.ext" to "b:"), but after that I receive a "Disk offline" when I try to access the drive. When I reselect the same virtual disk (by pushing the right button ten times) I can see that the file has actually been copied.
- Is it usual that I hear the b-drive humming when I acces the a-drive, or may I have connected the drives wrongly to the main board?

Does anybody have similar experiences with this gotek device? Or am I doing something wrong?

regards, Theo

The best way for use the gotek, is install the HxC firmware, but is not free, costs 12€

Somebody already tried with the keirf FlashFloppy firmware on a Gotek with MSX?

I guess you have to rename your .dsk images to .img (raw sector formats).
Although the latest version of the firmware also supports (Amstrad) .dsk, it looks to me this is a different .dsk disk format with a 256 byte header. Our MSX .dsk format does not have a header.

I have one with HxC firmware in a 8250 and another just arrived for my 8245.
I was also planning to try the FlashFloppy firmware. Whilst reading about it I came to the same conclusion, img is what we call dsk on msx. What they call dsk is something else indeed.
It should also support HFE images. With the HxC tool one can convert dmk images to HFE.
With the HxC firmware this way you can use protected disks. Hopefully this also works with FlashFloppy....

It works great with Flash Floppy, you don't have to rename the .DSK file
it works even with Folders i've got a Folder Demo,games and magazines
I would say Flash that gotek into FLASH FLOPPY

@ JohanMSX, if the DSK image is a 720kb image don't rename anything. A 360kb DSK image gives some problems. I think renaming it to IMG works for a 360kb disk. It's lots of fun to experiment with.

Thanks @roadfighter! I received the GOTEK last week and just flashed flashfloppy 0.9.7.a
Works perfect with both 360 and 720 KB disk images (just use the normal MSX .dsk format).

Great firmware.

Flashed GOTEK with FlashFloppy firmware, loading seems to be working fine. However if I try to write something, for example save a Basic program into the selected image, I get no errors, however the file doesn't appear there. Anyone has the same problem?
