![]() ![]() You can only write these on PC using a tool like CPCDiskXP.ĮDIT: If you use a different DOS on CPC like ParaDOS you have more disc formats available. It is 40 tracks, 1 side, 9 sectors per track, numbered &c1-&c9. My advice is save yourself loads of time, get a Gotek or HxC if you can afford one.ĮDIT: The 178KB disc format is AMSDOS's "DATA" format. So I guess it's a later version of windows with a USB drive and it doesn't know how to access it. On early versions of windows (95 and perhaps 98) didn't stop you accessing the floppy hardware so you could read of discs, later ones blocked this. Also, it depends on the version of windows. ![]() I think Winape assumes a floppy controller in the PC. It depends on how the emulator is accessing the drive, and also it depends on whether it is assuming a floppy controller inside the PC or a USB PC drive. On the CPC you need a 3.5" drive and preferably a way to configure it as drive A because many games boot from drive A - although this has improved a lot in the last few years. ![]() Later versions of windows are unlikely to support drives and also control access to the floppy controller hardware directly. If you are writing disks on the PC the tool you need to use is CPCDiskXP, but you need a PC with an on-board floppy controller (because this is the most powerful and the tool targets that) and most likely an older version of windows such as Windows XP. So they are limited in what you can do with them. So another issue is that the PC USB drives, the ones that plug into the PC, assume they are using PC disc formats and I expect FAT filesystem. Nowadays, Gotek's and HxC are used because you can put dsk directly onto a memory stick and put that into the Gotek and plug that like a drive into the CPC. You ideally want to be able to put a DSK on a PC 720K disc and then on the CPC (using a 3.5" drive on the CPC) re-build it.This is possible, unfortunately I can't remember the name of the tool. To read PC based disc format on the CPC you need a program called "DOSCopy". AMSDOS is also a single sided DOS because it assumes you take the disc out and turn it over. IBM disc format is something around 160KB a side. This is why you are seeing a low capacity. So what is happening here is that the CPC is not detecting the PC format correctly and assuming it's one of it's formats. Based on this it chooses one of it's formats and configures AMSDOS to read this. The CPC detects the disc format by reading track 0 and reading a sector ID from the track. If you're using AMSDOS then the filesystem is based on CP/M, it's different to FAT they are not compatible. I don't know which filesystem this format had on the PC. This is based on an early (late 1970's) disc format on the PC. This is 40 track, 1 side, 8 sectors per track numbered 1-8, 512 bytes per sector. The CPC has many disc formats including DATA, SYSTEM and the one of interest here called "IBM". The PC 720KB format is 80 track, two sides, 9 sectors per track numbered 1-9, 512 bytes for each sector. ![]()
