Yes this was expected.

About the the standard sector length, I had a look at the motherboard while verifying the pinout, the FDC is a standard VL1772-02 and the same model word processors were fitted with 720kb 3.5" FDDs later years. So maybe it is about that.
Roland firmware seems ok to me.
This is time this is better : the track is now complete !
Still the write sector issue. I have manually fixed the formatted image in the attached DSKA0000_ToRead.QD.
Can you just try to read it (without writing anything) ? (Think to remove the old DSKA0000.QD from the stick before the read attempt).
Then update to the new attached firmware (HxCUSBFE.UPD).
After the update try again to read DSKA0000_ToRead.QD and then try to format DSKA0001_ToFormat.QD. Share again the formatted file here.
Firmware update procedure :
Code: Select all
To update the firmware on your device with a FAT32/FAT16/FAT12 USB flash stick/key: -> Remove any older *.upd file from the stick (if present). -> Copy the attached new firmware file (*.upd) to the stick/key. -> Insert the USB stick/key into the emulator and press both buttons. -> Power up the device and keep the buttons pressed during at least 2 seconds. -> Wait some seconds... its done !
